@azulpiscina, you have to click the "Mount R/W" button at the top right of root explorer screen before you can edit files.

Trying, back in a minute with feedback.
thanks!

This ended up not working for me either. I have had this issue with this phone and others and it seems to come and go, raising it's ugly head again when I went with CM7.
I had a D-Link DIR 655 router and last night I replaced it with a TL-WR1043ND and so far the issue is gone. Signal strength is much better too.

Ive had no problem

Ive had no problem whatsoever with wifi on any cm7-rom ive installed.
Ive had rc1 and many nightlys installed and never had any issues with wifi.
My router is a Linksys wrt320n with dd-wrt software.

It didn't come with it but I flashed the new router with dd-wrt. I have not had any wifi issues since.
I was reading on the dd-wrt wiki about the N specs and discovered there is a setting in the old router that may fix the issue and also explains why some people have issues and some don't.

I installed CM rc 1.5 and I have a Linksys WRT54G at work (with dd-wrt) and one at home (original software), and i'm having this wifi disconnect issue in both.
I have 2 defys, the other running 2.2 and it's amazing to see the difference in the signal strength of the two ROMs running side by side.
I just tried deleting the file /data/misc/wifi/wpa_supplicant.conf and reboot (from this thread: http://forum.xda-developers.com/showthread.php?t=1161460&highlight=cm+wifi) in the last 10 minutes and so far so good, but it didn't seem to fix it for someone else in that thread in the long run. I'll report back here if it fixes it.
Update: That tip above didn't work, but now I'm using 110927 nightly and I don't see the disconnect issue anymore, and the weak signal seems to be gone too.

I also had wifi problems, always disconnecting. I found in the official motorola forums someone saying you should search in the router settings for an option called wmm or wme (windows media extension) and deactavate it. also use tkip instead of aes. im running cm7 rc 1.5 with a dlink dir 655 router. it solved my problem. didn't have any dissconects the last days.
hope this helps someone

Problem is, there are wifi issues in CM (at least for some people, like me). I don't have any problems in 2.2, with the same routers I always connect to. So I would guess we need to find what could be changed in CM to fix this issue, although I understand that changes in the routers can alleviate the issue.

Anyone knows where's the cfg of the wireless strenght icon on the top bar? I wanna change the value of the 4 stages.

i agreed with bra2006. it should be fixed in cm7, and not expecting any everyday users to muck around with their modem settings to get around it.
if some roms don't have problem, why should cm7? surely they can compare and work out why cm7 has problems while others don't.

I also have the same problem, with RC1 was ok, when I put RC1.5 began to disconnect the wifi

if you use WiFi usually.....it saves battery, and keeps WiFi connected until you disconnect it....

It might work!!

omg... i have the problem too. i was using bionic cow. last night i flashed the black notes but later i restored bionic cow and the settings using cwm. and wifi totally didnt work. oh no

I've just started getting the same problem since updating to the latest stock update. Thing is just after I also changed my router so not 100% sure if it's the phone or the router. My WiFi is ok but after I've not used it for a while I have to stop and start it again for it to work (the phone not the router).
When you say it was the routers problem what did you change in your settings? I've looked into mine and can't see anything that would cause it to disconnect the phone and my phone is set to 'never' disconnect in sleep policy.

i suppose this happened to me quite recently.
try having your network either on wcdma ONLY or GSM ONLY.

Thanks for the reply but I've sent my phone back to Samsung for a cleaning as it had dirt collecting under the screen. I mentioned on the return form about the Wifi so if they get back to me on that I'll post what they said.

Got my phone back from Samsung. Have to say great service. Sent on Tuesday and back repaired on Saturday. The WiFi problem was also sorted. They just put a note in saying 'We've installed the latest approved software as part of the standard repair service'. Funny as I thought I had updated to the latest just a few days before sending it off. Phone reads:
Android Version: 2.3.6
Baseband Version: I8150XXKL3
Kernal Version: [email protected]#3
Build Number: GINGEREAD.XXLA2
I'm in the UK so if anyone else is having this problem update to this and hopefully it should fix it.

WiFi Connection problem. ( Network Disabled. Poor connection)

The weird part is it says "Network Disabled. Poor connection." but the bar is strong. It has always worked up until the last 24 hours. No god damn google-ing was helping. It is set to wpa/wpa2 PSK.
What the hell is wrong with it. The 4glte works. I haven't downloaded anything obscure.
Provider Telus.

Wow, I now have the exact same problem with my SGS3 (international version without LTE). I already tried "forget this network" on my phone and "delete this device" on my router but it still wouldn't connect.
I installed the official JB update a couple of days ago. Never had that problem before.
Edit:
I could fix it by disabling DHCP and instead assigning it a static IP in my network. Though it is still a bug because if I'm in someone else's network (e.g. Starbucks) I usually wouldn't be able to use this solution.

Okay, it stopped working the next day and now everything I try, I can't get WiFi to work.
****ing piece of **** phone. Since the official Jelly Bean-Update (my phone is not rooted and no custom rom or whatever) several things stopped working. My ****ing Google Calendar just won't sync anymore (says "sync is currently experiencing problems, will be back shortly" for 2 weeks now), ****ing WiFi stopped working. I'm really pissed right now, mostly because I didn't customize my phone for exactly those reasons!!!

Honestly, what were you expecting? touchwiz is notoriously known for being absolute trash. None of the issues you've brought up occur on custom ROMs. Bite the bullet and flash one already.

My solution for "Network disabled. Poor connection" problem.
I had exactly the same problem today (SII, ANdroid 4.1.2 - Samsung leaked) but the history was a bit different. After the flashing all worked fine for several days. Today I upgraded my WiFi router with the new firmware (before I used the 5 years old one) and on my Droid the problem occurs. What is important, I got 3 devices in the home network: my Samsung Galaxy S II I mentioned, and 2 others - HTC Desire HD and Galaxy Ace - both with tje Android 2*. WHat was strande, only HTC worked withut any problems, both - Galaxy and Ace stopped connecting to WiFi.
I read a lot of posts, i undersand that the available solutions are: static IP (not acceptable, I need to connect to different WiFI networks every day) or rooting phone and clearing DHCP configuration on the phone (not available without root, as in my case). But - because everything worked ok before, without any changes on the phones (!) and as I read in the posts the problem is network-related, I decided to find the issue in the router configuration. So I cleaned the conf. of the router (reset to thefactory default settings), removed the information about my network from the phones, connected my phone to the "Clean" unprotected WiFi (default WiFi set-up after the reset), and then step-by-step added more security configuration on my router. First - changing the WiFi SID name, through the wireless mode (AP), then network mode - from B to Mixed, and then security modes WEP, WPA, WPA2 and algorithms: TKIP, TKIP+AEP. After every change on the router (several router restarts needed unfortunately) i tried to connect my phone to the WiFi. Finally I added the MAC filter. And... everything works OK! :laugh:
I propose to test the same solution. In my opinion the phone will connect without any problems to the unsecured WiFi, then one can find which step, which area of the config cause the problem - if it is solved when setting the mixed network (B/G) or maybe some of the security algorithms are not accepted.
I know that in fact it is not the fastest solution, but in my case the problem was solved - I got the same security level and settings as before when I had this error! Probably the changing settings of the connection which must be aplied by Android, do quite big 'revolution' in the DHCP conf. files of the phone, and the result is the same as after clearing the folders after rooting.
I hope my solution could be helpful!

No need, mine works fine...

I have exactly the same problem. Started right after the 4.1.2 update (SGS3 international). Unable to connect to any secured WiFi. Always the same: connecting -> authenticating -> obtaining IP address -> disabled (and a popup about poor connection).
Sometimes it does connect if I reboot or first reboot after factory reset.
Tried about 4 different routers. Factory defaults. Still the same.
I guess it's time for an unofficial ROM...

Stock JB ROM? Router model? 2.4 or 5Ghz?

I had this exact same problem, I had 4.1.1 and I odin flashed to 4.0.4 thinking it was the JB update. I found out that my Wifi password was off by 1 number and instead of the phone telling me my password was wrong it would throw that error at me. As soon as I double/triple checked my password and entered the correct one, my phone has been working fine ever since. I am on stock 4.1.1 JB.

Did anyone find a solution to the Wifi Problem on 4.1.2?
Regards

I think i found a fix, for some!

Some routers can broadcast on both frequencies simultaneously with different SSID's. I know newer Netgear routers do this.

Mine is still upset most times even on 5ghz. Forgetting the network seems to fix it for me. It is just a pain to do that dance every to time I get home.

notes on my exact situation
-wifi works fine on many open networks and private networks for both myself and my gf (both using galaxy s3 phones)
-the specific network is a private network at a business (my gf is the owner of the business so we have access to the router and its settings)
-we have both previously connected to this network before without any issue.
today neither of us could connect to this network. we restarted our phones, the router, "forgot" the network, and eventually gave up.
This is very frustrating as we both spend a good amount of time in the business (coffee shop) and it seems that no one else has connection issues, not other phones, not laptops or tablets, not anyone else. Both of our galaxy s3's just keep coming up empty on this one network.

Help!
I have the same problem after root my i9500 with CF-Autoroot on 4.3.
Already tried everithing but after some time from root it lost connection and can't connect again, even on other router.
With 4.2 always worked fine. But now, if I do the root process the wifi works only for 5 minutes.
It start with the first 4.3 update, but even now with the last 4.3 I9500XXUEMJ9 I can't root.
The "Network Disabled. Poor connection" is the only problem, everithing works fine. The root is ok. Knox freezed.
But now I have to flash the stock firmware again to get wifi working. That is the only solution (remove root) until now.
Any help?

[Q] Why isn't by LG4 getting any internet from WiFi (5Ghz and 2.4 Ghz)

Hey people!
So my Lg G4 (H815) arrived today I was running through the setup and noticed that it struggled to connected to my WiFi at first. I just skipped past it thinking it would fix itself once it fully installed and turned on. However it is having trouble getting the internet access. Anyone come across this issue? I have tried a factory reset with no luck. I was considering flashing a a rooted firmware to see if this resolves the issue but later read that the current ROM doesnt work well with Taiwan imports.
Note: This is the Taiwan import.

I have an issue not connecting, but my speed. It's SOOOOOOO slow when I connect to Wifi, but blazing when on data. I have seen from other threads it's an issue with 5gHz but 2.4 should be fine. I'm going to check my router when I'm at home in a few hours to see if that fixes it.

I had same troubles with Wi-Fi to the point where I was packaging it up to return and did a factory reset. This APPEARS to have helped my Wi-Fi issues

I am having similar issues on my AT&T variant. I've tried 5ghz and 2.4ghz. Same issues on both bands. I also tried a factory reset. Didn't help at all.
I bought the phone last Saturday. I'm considering returning it.

Same on unlocked 815 wifi just dies during transfer lg UK were none to helpful suggested reset did that then buy another router, finally after 30mins he decided it could be a hardware problem and suggested I return my handset.

Ok, so i had the LG G Flex 2 on AT&T when it first came out. And this exact issue cropped up. I thought it was maybe, well, the Flex 2 was a terrible phone anyways, so figured it was par for the course.
Next up, got the G4 H810 on AT&T, SAME ISSUE. Mind boggling. The other household device, LG G3 AT&T , never a hiccup.
So i'm figuring, maybe LG has changed something somewhere, until i realize, its only my home WiFi this issue happens. Worse thing was it's so random, Chrome works fine, FB loads terrible, Weather App can't grab GPS... So i was getting pretty frustrated.
I decided to check my router settings, and for whatever reason, i fired up the guest network and attached to that instead. BOOM, issue resolved without lifting a finger (other than changing wifi networks).
Why my guest network works, and the main does not, NO clue.
Must be a router security protocol situation. I will see what the difference is when i'm able to check the router settings again. Clearly, there is a difference somewhere, but why it affects the G4, I can only blame LG on this one.
FYI - rebooting router, nor factory resetting your G4 will fix the issue - there are other things at work here.
ALSO, my equipment is a cable modem router combo, Netgear C6300 - late 2014 model -

The Guest Network ability is a feature of the router. Your router would have to have this feature.
Typically also setup with its' own SSID and password, but again, it would be within the settings of your router, if you can setup a guest network. :cyclops:
I also only consider this a current 'work around', as my phone doesn't need to share content across the LAN to any other equipment, so it just having internet access works for me. But still no clue to the technical nature of why is has the issue in the first place. I also used to believe i was alone in the matter early adopting the G Flex 2, i guess nobody bought that device, since i couldn't find anyone else online having the issue.

I also only consider this a current 'work around', as my phone doesn't need to share content across the LAN to any other equipment, so it just having internet access works for me. But still no clue to the technical nature of why is has the issue in the first place. I also used to believe i was alone in the matter early adopting the G Flex 2, i guess nobody bought that device, since i couldn't find anyone else online having the issue.

Now I am interested too so I will be testing the guest network! I am going to probably leave it unlocked just to see if it is really not the security protocol. I usually run on the WPA2 AES could be something that the phone is unable to handle. So I will check and report back, I really do hope this fixes it because this is the issue that makes me hate my phone so far!

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?

WiFi abbruch

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.
