2 Issues with Galaxy Nexus: Wifi + Multitouch, temporary fixes inside!

Issue 1: Multitouch issue
- As far as I'm aware of, there is no fix yet and a lot of people are experiencing the issue. What happens is whilst in landscape mode, sometimes, if one finger is placed at the bottom left of the screen, and another is placed on the bottom right, it'll fail to recognize the second touch (bottom right). This doesn't always occur, but does happen at times.
Simple fix: Lock the screen, then unlock it
Issue 2: Wifi consistently dropping
While downloading files, or sometimes even watching youtube videos, the wifi icon will disappear for a split second, then come back and an error will appear along the lines of " File could not be downloaded due to an error" or in the case of the market, it'll just stop downloading and give an error.
Fix: Sadly, the only fix that I have found so far for this issue is to get a new router. See my post here I used a Linksys WRT300N
EDIT: Another potential fix is to change some settings with the router but I'm not sure exactly what settings are needed to be changed.
EDIT2: I've created an issue about the wifi issue over here and according to [email protected]:
Im assuming you are downloading huge files using WiFi... there is a notorious bug still unresolved on DHCP leasing time. If your route is settled to infinite (0 or ffffffff) a local timeout of few minutes is applied, thus the download broke and resume time by time because dhcp renewal. To fix this try to adjust your route settings indicating a discrete leasing time (i.e. 24 hours or 2 days) and thi should fix this specific issue (also noticeble when watching youtube videos, that may freeze after few minutes).
Hope this helps.

Hey everyone,
I have had my Galaxy Nexus from Bell for a few days now, and it is a beast Everything runs smoothly, no lag (even with live wallpaper) and helps me accomplish everything I need from a mobile device ( a hell of a lot better than the milestone - international version of the Droid)
However, there are some prominent issues throughout the device.
1.) The wifi constantly times out, it will stop working at random times even if im 1-2 ft away from the router. Also, when I was downloading SD files for a game (asphalt 6 - 524mb file i think), i had to restart the download at least 10-15 times to finally get it to download. Is this a hardware issue? Can this be fixed through a software update
2.) The multitouch doesn't work at random times. For me, whether its plugged into the charger or not, at random times, when you touch the left side of the device in landscape mode, the device will not recognize touch inputs on the right side. HOWEVER, if you lock the screen, then unlock it, it works flawlessly. I am determined this is a software bug (may not be though) and if it isn't could someone please tell me? Thanks. And a lot of people also have this issue : http://forum.xda-developers.com/showthread.php?t=1385587

I have two question for you awesome people at XDA.
1.) Could someone please either post an issue to Google regarding these two issues or direct me to a website where I can post them?
2.) Could any of these be a hardware issue? Do you think I should return it and get another one?
Thanks so much guys,
Mosh

Would also like to know if the second problem is software related or not :/
EDIT: noticed now that my screen gets really hot at the top. Really hot! Does your get warm aswell?

Don't know. The easy fix is to swap it.

Both my touchscreen and WiFi have been working flawlessly.
I did have some initial hiccups with the WiFi until I power cycled my router.

Make sure 'Avoid poor connections" is ticked off in the advanced WiFi settings.

I've been having WiFi trouble with the Nexus too - the phone generally seems to get poorer signal in comparison to my other devices. I've unticked this box, but it still keeps avoiding connecting (and when I go to WiFi settings, actually says it's avoiding connecting to my network because the connection is poor). It's frustrating, to say the least.

Rather than immediately assume that you should swap the phone, or thinking it's hardware, or (?).
What build do you have? There are at least 3 builds available for the SGN.

Seriously people need to stop making such a big deal of these separate builds.

WiFi could be an issue with the router. I had a problem where connecting Nexus to the router would cause both mine and other users internet in the network fail. Once I disconnected, internet returned. It worked on first few loads, then not anymore. Strange thing is that it fixed itself few weeks later.
(Same happened once with another router and when I was using HTC Desire, Android seems to be a wacky WiFi partner)

Not this. If its software you end up with another phone with the same problem.
You may find other radios help with wifi, check the dev section for details if you have a rooted device. Otherwise youll probably need to wait for one of them to drop via an official ota.
As others have said, uncheck the weak wifi option
In terms of the multitouch issue, just tested my device and can't see any issues at all. Could be software related as the screen itself can support 10inputs - be interesting for users on non standard roms to check and see if they do have a problem as this may lend some weight towards the software related argument.

I get #2 in shadow gun if it goes into sleep mode while i'm playing. Its clearly a software issue as restarting the game it goes away.

Point 1 happens to me too. I've tried multiple ROM's. I'm getting a bit worried that it's hardware. It's dropping every few mins when I need it... then it comes back rather quick.
You have any news or has anyone else experienced it?

I'm not seeing a ton of people talk about this wifi problem, so I'm guessing it's not a widespread issue. I'm assuming it's not hardware either, but I'm curious about it. Whenever I turn on wifi on the Nexus and it tries to connect to my router, it disables all other connections, and the Nexus reports that it's not in range of the router. I'm interested in what routers people are using that are experiencing this issue.
I have a D-Link DI-624, a free router provided by Verizon with FIOS signup. I'm using a custom password, not the one that came with the device. I have a 13 digit alphanumeric password (sorry, I can't remember the exact security setting for it).
Edit: Actually been doing some research on this, and it's appearing it may be a frequency / channel issue, that the phone is broadcasting at a frequency similar to your router. Looking into exact fixes at the moment.

I have no problem with wifi and multi touch.
But I noticed that two fingers cannot be very closely touched it will mingle together. For example if you hold shift button on keyboard it could act like normal shift (turn lowercase to upper or vice versa) but its very difficult to use shift + a
Also lots of games exiting on me, first I thought was multi touch acting up so I could accidentally hit home or back button. But then I think its just matter or compatibility of those games with ICS.

do you know if the latest update solved the touch problem?

Same issues here. On the samung version (dont remember the codename) i had this issue so i rooted and changed it so that google updates my phone. But this didn't help either. Still losing wifi when i am downloading. Like now i was going to download 9mm and after 2 seconds the wifi disconnect until i quit 9mm and then it pops up straight away. Can it be a hardware issue?
PS: before i change my phone brand to google, i could see the "avoid poor wifi connection" but now when i go to advanced tab it's gone :S

Ok everytime i try to test wifi in speedtest it says network communication issues after 2 sec of testing. Any info please? Do i have a faulty unit? going crazy over here

For what it's worth, I haven't had either of these problems on my Galaxy Nexus, and it's been on a lot of WiFi networks.
I've gotten speeds in excess of 20mbit/20mbit via the speedtest.net app multiple times on the campus wifi, as well as my parents', and my dorm connections. I've downloaded the Asphalt files twice without any interruptions either time, and I've never experienced any problems.
As for multitouch - no problems with that either. To type in all caps you can hold down the caps button on the keyboard and type - it's never given me any issues. I don't think I've been in a situation where I've felt multitouch hasn't performed right.

Multiple ROMs doesn't mean much, they all share official driver binaries and radios that are available.

Then i probably got a faulty unit. Will give it 2 more days and if it's still the same i'll return it.

Tethering On the Go Borked

I can't get this phone to tether for more than 2 minutes or so without it not working. The data will simply stop transmitting to the tethered device, while still working find on the phone.
An example is streaming Netflix while driving. I can do it on the phone just fine, but it freezes off and on before stopping altogether on my ASUS Transformer. If I am at home the tethering seems to continue working for hours.
The problem does not occur on the HTC Thunderbolt that my new GN is replacing. I assume this has to do with how the phone handles the transition between towers. There are lots of dead spots along the routes I drive, while delivering pizzas, but they are usually at intersections and are only an issue if I am stopped at the light for too long without sufficient buffer for the video I am streaming.
I have tried ARHD and RootzBoat. Used android-wifi-tether, the built in ICS tether, and the trial for the 10$ wifi hotspot app by SVTP(or something like that).
Please help me. This problem is so frustrating and unyielding I am ready to cry.

Well, if you are moving you will not get fast speeds nor a stable connection. When moving and requesting data you become lower priority on the tower/s not to mention youre just going to get **** for speed because of all the calculating and power necessart to get you that data. Voice is much higher priority and uses less bandwidth and power and will transition much better between towers. You should be driving anyways and not watching netflix. Worse than texting.

This is not true. LTE is designed specifically to work for high-speed travel without degrading throughput. And tower handoffs do not lower your service priority. Agree that if the OP is trying to watch movies while driving, he'll be in an accident in no time. REALLY really bad idea.

These conditions are were childs play for the HTC Thunderbolt. The issue I am speaking of is particular to the GN. That's why I am posting this.

For now I will put a hold on this question. The issue arose today on my home WiFi. As such I think the issue might actually lie in the ASUS Transformer Prime, as the issue isn't present in my ASUS Transformer nonprime. I'll report back within 24 hours when I have tested both devices concurrently.

Oh damn. Now that you mention it, transformer prime has wifi issues. Thats why there is a hold on them.

Tethering isn't stable for me either while using wifi tether. But worked just fine with the stick app. What rom are you running?

I turned bluetooth off and was able to stream just fine while driving around town today. I didn't actually watch anything but the connection was stable for hours. I did have one random reboot though.

Why on earth are you driving and watching movies? whats really insane is the fact your posting this like its normal.

Stay on point. I am not asking for your permission to use my devices how I see fit. I am pointing out an issue. I determined that the issue lies with the Transformer Prime, and not the Galaxy Nexus. So you can stop responding to this thread and stop preaching to me. I know what I can and can't do safely. I have no desire to get in a wreck, and as such I have never been in a wreck or anything close because of a phone or other gadget. I can also say that I never will be because I watch the road when my car is moving, simple as that.

So I made two very unprofessional videos that show the issue. It took longer than I wanted to completely kill the connections, but the evidence is there, the wifi becomes spotty and unusable after a while.
I also did a little bit of a side by side with the original transformer.

My grandma beat me down and took my nexus. Sent from a jitterbug with beats audio by dre.

I am actually having the same issue except I am not driving anywhere, the phone stays in one place. I used my Thunderbolt to tether to my ipad2 to stream tv shows while at the gym doing cardio. Unless the 4G signal sucked on the Thunderbolt, it would be able to stream a 350 meg show over Airvideo on the ipad2 no problem. I just switched over to the Nexus, rooted and romed with AOKP build 21 (kernel that came with it) and using the built in wifi tether app as well as a 3rd party installation of Wifi Tether yields the same result... the data will just stop transmitting randomly but still work fine on the phone. First time it stopped after about 200megs transmitted.. then 80, then 38.... without any reason. Signal was fine. Only way to temporarily fix it is to turn off the hotspot and then back on. But then it arbitrarily cuts out again.
Could it be the kernel? Or just something different about how the Nexus treats constant transmission that sucks compared to the older LTE phones? Please someone help!! this is the #1 reason I root!! I like to stream video onto the ipad2 almost daily....
:-/

i've posted this issue in another thread. there seems to be quite a few ppl with this problem. tether is active, device connected to genx is showing full signal, yet after a few minutes internet connection is lost while tethering is still active. What I have found works for me is setting the tether network to OPEN. internet connection stays on.
btw. i have i had the issue since aokp 14 till now Milestone 3, all running Franco's kernels and i have also tried a few other kernels. problem started when i started running aosp 4.3 base roms i believe. for now an open network will have to suffice when I need to tether. gl.

Thanks for the tip but that isn't working for me unfortunately... tried a number of different things this morning but still the same random disconnection while tether is on... :-(
Tried turning off bluetooth... changing the LAN settings from 192.x.x.x to 10.x.x.x... force wifi driver reload.... routing fix on/off... goddamnit. I used tether almost every day almost flawlessly with my Thunderbolt.

I seem to have the issue with bluetooth tethering. The first time I tried it it seemed to work just fine, streaming a podcast for over an hour straight.
But I just tried it now to my MacBook Pro and it disconnects in about ~2 minutes after starting over and over again. I'm using all the same settings that worked before and worked on my G2 as well.
Using WiFi tethering now and it seems to be working. I prefer bluetooth though when I just need to tether to one device. Does no one have a solution to this?
I'm on a GSM version stock 4.0.2.

Wi-Fi unreliable

Recently I've been having problems with Wi-Fi. My phone and nexus 7. They both stay on blue bars all the time claiming they're connected to Google servers. And it'll work good for about 20 seconds and then I'll have no connection for about a minute. Bars will stay blue like its connected and WiFi show that it's fill signal but pages won't load, apps will timeout and YouTube videos won't stream. Makes it impossible to download any Roms or apps at times. This just recently started happening. Videos will stream good for maybe 2 minutes tops. Then pause, after a minute Wi-Fi will stay streaming and going again by itself and stream. I haven't changed my router or is settings. I have static ip's assigned too. All other computers work just fine for internet. Never a problem.
I've tried changing kernels, Roms, complete wipes and reinstalls. Rebooted the router. Nothing fixes it. I'm getting really frustrated. I'm at the point where I'm going trio go buy a new router just cause I want to use 5ghz. Anyways, any suggestions to solve this?

There may be an error in aosp code that can cause wifi instability: http://forum.xda-developers.com/showpost.php?p=35146886&postcount=5128

Weird how it affects just my device in an entire thread with a ton of people using the rom and same kernel.
I went and picked up a new router. I'll see if that fixes it. Thanks for the input though. I appreciate it.

Didn't help with new router. My WiFi still cutting out like crazy on Franco kernel. Almost as soon as I turn off screen. But its not turning WiFi off. Just goes into some sort of state where nothing comes through. When screen on everything is fine though now.

In Wifi settings, you could try unchecking "Avoid Poor Connections" and see if that helps.
Also do you have any other devices at home on the same wifi network - do they experience the same issues, I know where I am if we get a lot of rain, it causes intermittent internet slowdowns, I had similar issues and after testing other devices found this to be my problem not my Wifi.
Also, have you got any cordless phones in the house that might run on the same frequency?
I still have an issue keeping wifi at 100% d/l when the phone is asleep, even though the setting is for always on. It must be a hardware thing for me because every rom I've tried from ICS to the latest JB exhibit the same issue. If I am in a desperate need to d/l a large file on my phone, I just temporarily change the screen display off timer to 10 minutes of so so the wifi will stay at max d/l speed.

Ya avoid poor connections is unchecked. And wifi optimization is unchecked. I've tried putting my router on full auto, tried setting static ip addresses for everything. Changing from wireless n to wireless g. Changing security to off as well. Using the 5ghz band instead of 2.4. The nexus 7 is working perfectly fine with the new router. But my galaxy nexus is totally unreliable. Weird is that it just started happening within past couple weeks. And actually, it was good for the first day or so after new router. I can confirm all other wifi devices jn the house work just fine without any hiccups. I've never had a problem with other devices. No dropouts or anything. It's really puzzling me!
One thing I found weird, if I disable wmm on my router, my nexus 7 and galaxy nexus will not connect. Anyone else get this?

I hope you also have your router firmware completely up to date.

Ya my router auto updates itself. Its a Cisco EA6500 in case your wondering and is helpful.

I use my wifi at work and it's very unreliable. At times going into an endless disconnect/reconnect loop. Sometimes restarting the wifi helps or putting it in and out of airplane mode. Other times nothing helps except a reboot of my phone. Some apps may make the issue worse. I don't think there is a fix and waiting for google to fix the flaw a user pointed out earlier.

Possibly a 4.2 issue. But its not affecting everyone it seems. But i see that there is a huge thread about this at the google site. Not an isolated case

When you say you set a static ip, you set one from the router, have you tried setting a static ip on the phones wifi advanced options as well?
Have you tried different radios?

Yup has happened to me mine connects to the net but has grey bars and doesn't open any websites and apps dont connect to the net a reboot solves the problem

I set static on both router and the phone. I've tried all the north american radios. None of the euro ones. no effect. Sticking to the latest North American radio for now. I've managed to make it work sorta with CM10.1 with stock kernel on completely fresh install. It works, but the down arrow on the Wi-Fi icon stays lit almost 100% of the time. no idea why, only other device that was on all yesterday was the nexus 7, and that was on the 2.4ghz and phone the 5ghz. Huge wlan_rx_wake!

It's likely this:

When i first updated to 4.2, I was getting crazy dropouts. After unchecking the Wi-fi optimization, it was more consistent but still drops out frequently while at work. There is a known bug with the wifi driver that hasn't been addressed for years, but still trying to find the original articles describing the problems.
It seems you are having tons of issues, worse than most.
If you are having a problems suggested on this site, maybe this can help.

It affects me as well. Completely random. Everything appears fine except that instead of blue, the icons are grey. Turning off wifi and turning it back on fixes it.
In the link above, there is a comment where you can submit more info for Google to help solving the problem:

the weird thing is, it just started happening about 2 weeks ago. It was perfectly fine up until then. Never had an issue with Wi-Fi. If this don't work i might try doing an entire wipe right back to stock and locking bootloader.

Note 2 WiFi battery drain (GT-N7100)

Hi! Lets make this work please!
My battery drains 30-40% over night when I'm connected to my home WiFi. Now here is what I did:
1. Tried other WiFi networks and none of them drain battery like my home network.
2. Changed Roms (both tw and cm based)
3. Changed kernels
4. Changed bootloader
5. Changed modems
6. Changed battery
7. This is where I concluded that my phone couldn't be the problem so I've decided to change my home router.
8. Tried to change wpa2-psk--> wep.
9. Tried to change configuration with my network provider.
10. Tried third router as my last option.
None of this helped me, and I'm not seeing any link between all of these that could be my problem. All of this started after 1 year of owning my phone, and has been going for about half a year now. I would like any suggestions as I'm out of ideas right now. Sorry for the long post :/

7. This is where I concluded that my phone couldn't be the problem so I've decided to change my home router.
8. Tried to change wpa2-psk--> wep.
9. Tried to change configuration with my network provider.
10. Tried third router as my last option.
None of this helped me, and I'm not seeing any link between all of these that could be my problem. All of this started after 1 year of owning my phone, and has been going for about half a year now. I would like any suggestions as I'm out of ideas right now. Sorry for the long post :/

It is clear that your phone is alright. So this forum won't be much help.

Yeah, but I can't find anything that could work so that's why I made this thread, maybe someone can give me a good advice or an idea what to do next. Thanks anyway
"The music is different here."

If you are in an area where there are lots of other wifi signals around, I would try to change the wifi router to a different channel.
I had some other wifi issues until I figured out everyone around me was saturating the specific channel I was using.
I used the app wifi analyzer on the play store, and selected a channel that no one was using for my router.
Not saying that it will definitely solve your issues, but it is worth a try.

Thanks for the reply I have tried changing WiFi channels but it didn't work, however I didn't use any apk but directly from my router. I will definitely try this when I get home though!

The app just shows what channels are used around you and it's strength. In the attached pic there is not much wifi around but as an example I moved my channel on my router from 1 to 6 since there is already 2 other ones on 1.
Normally it is bad mobile reception though that drains battery like mad. Do you have good reception where you are located? Leave your mobile data off for the night to test whether that was the cause. You have swapped routers, so it could probably be mobile related at your location.
I know you have tried modems. I upgraded my Note II to newer firmware but had horrific reception causing bad battery life at some locations . Flashing only the older modern from my previous firmware sorted that. You tried that, so no help there.
If you are on touchwiz based rom you can look at disabling fast dormancy via the store app too. Some mobile networks / towers don't support it and can cause drain like mad.
Good luck.

Yo! My network reception is really good where I live so no problem there, my battery drain is horrible only on my home WiFi network. When I connect to my neighbor's wifi I get barely any drain even though it barely catches any signal from it. I will look into this fast dormancy thingie as I have no idea what that is, and test it again. I'm in another town right now on college, but I'll get home as soon as I can to try this, and maybe try changing my channels again. Thanks for your help and suggestions, I'll just try to get as many ideas as I can right now so I can test the sh*t out of my phone

Your wifi is possessed dude. Safer to stay in the other town for now... Lol. Anyway enjoy and good luck.

Poor WiFi performance

Hi everyone,
I've noticed that when this phone is a bit away from the AP I get poor or no traffic even though the signal levels are good, which makes me believe the RX or sending signal is low which makes it impossible for the phone to talk back to the AP. Perhaps the Wireless antenna layout in this phone is flawed or maybe only in my phone. Anyone else noticing similarly results?
Also engineering mode says 5GHz wireless as supported by the chip, wonder if it's possible to show up in the wireless settings? Maybe it's disabled because of China restrictions?

I have the same issues.... When I am far from the AP even though it will connect with a decent signal (two bars) after a while it will lose connection and try to reconnect and once it does, it will lose the signal again and again... I have also noticed that this does not happen so easily with 802.11n APs. I have installed the Wifi fixer app which allows the phone to reconnect almost immediately and this has minimized the problem but it very annoying.
I do not know if this is an antenna issue since it does actually discover many wifi networks that may even be in buildings across the street and also because I have seen an improvement with the latest 0909 firmware.
The problem however does exist even with the flyme version. I haven't tried eragon's version yet since I am waiting for the one based on the 0909. It is a baffling problem...
The main problems for me with this phone are the wifi disconnections and the gps accuracy, if these two are solved I believe that this is a phone that I would happily keep for a couple of years. I keep my fingers crossed hoping that the developers will find a way to solve these.

I doubt that these Wifi-problems can be solved by a mod. I regularly observe that there is no wifi throughput, even though signal strength is absolutely OK. After disabling and re-enabling wifi all is good again - for a certain time. To me it looks more like a software problem that prevents data to flow even though there is a good enough wifi connection, maybe something wrong in the network stack. As for the 5GHz: Most modern chipsets support both bands, but as far as I know separate (at least: special) antennas are required to support 5GHz. Could be there is just no adequate antenna built into our P8000...

I also have the issue you describe Brewn - I first posted in the Eragon thread but it's better in this one(copied the conversation below...) I have found no fix either and it's v.annoying!

It would seem so, yes. Sorry about that.
From your description it seems to be the ”ghost bug” which plagues Android 5.0 + and affects with the exact same symptoms cellular data, Wi-Fi or both - with or without an exclamation sign over their corresponding icon(s). There's no permanent fix at the moment, but you must know that Google itself rolled out 5.1, 5.1.1 and 5.1.2 trying to weed it out (and other bugs as well, but especially this one). It can affect any device, irrespective of the brand.
Another possible explanation would be a hardware fault - such as a bad antenna connection or worse.
There may very well exist an app like the one you're describing, but that function is built-in Android since at least 2.2. Check it yourself by entering system settings/Wi-Fi, then from the menu (the three dots) tap Advanced. Then tap ”Keep Wi-Fi on during sleep” and check ”Always” if it isn't already so. Note that if you have installed any power saving app, those too can disable Wi-Fi while the screen is off. Android itself does exactly that (and more), cutting off any radio data when the power is too low.
You may want to post this in Troubleshooting too. Let us know how it went! Best of luck! 

Thanks for your suggestions, it does sound a bit like the ghost bug but it is annoying that there is no fix...my wifi during sleep was set to always so I've just changed it(a few hours ago) to never but I don't think that will make a difference somehow, a hardware fault is possible I guess but the random nature is weird? I am looking for an app that kinda toggles wifi off during sleep then on when screen wakes up - don't know if this will help(if hardware fault then I guess not!) perhaps I should stick it in troubleshooting as it is driving me nuts!

Hi everybody,
a couple of firmware versions and kernels later this topic is still not addressed.
On my P8000 I can regularly (say every 30-90 minutes) reproduce the following:
I am connected to a Wifi, the connection is good and I get decent transfer rates. After a while, no data gets through anymore, despite the wifi signal still being strong. After turning wifi off and on it immediately works again.
It does not matter what wifi network I connect to, it's the same at work, at home, at the hotel lobby - anywhere. And it has been like this ever since I got the phone, with stock and eragon ROMs.
The thing is: From looking at the phone I can not tell if it is connected or not. I have full wifi reception and full 4G, but still (as wifi has priority) as a matter of fact I am not connected. This is bloody annoying when waiting for an E-Mail or a whatsapp to come in, because I have to disable wifi to make sure I get the message on time.
Am I really the only one with this problem?
Cheers,
D

Hi,
I only bought the P8000 last week and observed this problem at home when I connected the P8000 to my WiFi network consisting of three access points on different floors of my house using the same SSID. The phone could not receive from or sent data to the internet after I changed the floor and the phone connected to the access point on that specific floor.
After changing the SSID of two of those access points and every access point using its own SSID now the problem seems to have gone. I don't have it anymore for three days now.

Hi,
while I have the same setup at home and at work (multiple access points with the same SSID) it is no option to change that setup. It's also a very common setup at public places.
At least this seems to narrow the problem down to a faulty implementation of the wifi drivers. Is anybody capable of looking at the sources or give me a pointer to the driver sources?
EDIT: Check out the app WiFi Roaming Fix - it is supposed to fix problems with many APs having the same SSID. I am trying it right now.
EDIT 2: OK, seems to work. The app crashes sometimes but does it's job. I have not been offline in the last 4 hours.

can you guys test this kernel version?
Changed to different wifi drivers ++
Works with 909 rom (eragon)
Is there any changes?

sorry english (or norwegian) only

For me this kernel solves the issue. Great work!

I have the problem after 30-60min the wifi signal is normal/strong but there is no dataflow at all. It only helps to restart the router. I have no problems with other wlan devices. the problem is the same on two p8000. I dont want to install any kernel or roms because of warranty.. i can send the phones back 14 days. If there are no official solution i need to refund them =(

Please could you modify wifi in the latest kernel stock ROM 20151105?
Or modify wifi in visi0nary's kernel - http://forum.xda-developers.com/elephone-p8000/orig-development/kernel-visi0narys-kernel-t3226081
I am using it, is excellent, but would like to improve wi-fi.
Thanks.

ok... so i'm a newbie, but i have the same problem with my p8000.
Can you explain how to apply that kernel version?
currently i have 3.10.65 kernel version, and custom build version 20151105..

Could you describe what you did exactly to fix this problem?
I have the exact same wifi issue on the elephone P6000 and I am trying to fix it for months...
Thanks!

Can you please do the same wifi adaptations in the latest core of the stock ROM 20151105?
Thanks.

Can you guys try the tiltkernel 1.5wifi to see if that helps or like me try the WiFi roaming fix app which was mentioned over on that thread and it seems to be better for me than the WiFi fixer(donate) app which I had been using for a while. I can't use that kernel as dt2w doesn't work for me unfortunately.

Looks like @tiltkoko83s fix works! If it can pass my tests I'll merge it into my kernel upstream.
Thanks tiltkoko83

I think I've noticed this on my P6000 Pro too.
Can anyone give steps to prove the bug exists?

Hi tiltkoko83,
I've already written that latest stock ROM "20151105" (and earlier versions also) has serious Wifi performance problem. Now I have made a comparison phones: Elephone P8000 and Lenovo P770 - the same place, the same router, only one phone connected to router in the same time. Result: Elephone P8000 is 5 times slower than the old phone Lenovo P770. It occurs in areas with poor Wi-Fi signal.
Could you make for us Wifi modifications for latest kernel 20151105 please? Thanks.
