[Q] Wireless Tether suddenly not working

I had Wireless Tether 2.0.5 and 2.0.6 working without issue. I updated to 2.0.7 via market update and now it will not work. My laptop see's the network but will not gain internet access. I also noticed that while upload keeps going, download gets stuck at .4kB total.
I have tried on my computer using Windows 7 ultimate 64, ubuntu 10.10 x64, and PS3. All 3 see the network but cannot gain internet access. I also tried version of Wireless Tehter ranging from 2.0.5 stable to 2.0.8 experimental. All versions act the same.
Any ideas why im having issues, looking in the apps log it appears everything is fine.
Ive tried it open network and secured as well as access control on/off. none of the settings seem to effect this. Thanks.
Edit: the only change ive made since it last worked that i can think may have affected this was updating kernel from my sig to 4.3.4

Well, I would try one of two things, or just both. You said it started right after you updated the wireless tether app? I would try rolling back to the last version that was working. You can go to menu>settings>applications>manage applications> then find the wireless tether app. Once you select it, there should be a button that says 'uninstall updates'. Hit that, and it will revert youb ack to the last version. Also, you noted that you also changed kernels. I have had certain kernels break my ability to tether for some reason or another. No idea why. You could also try going to the previous kernel you were on.

Unfortunately I don't the rollback is an option tho ill look into it. As for the kernel I'm beginning to think maybe that was the culprit but ill have to wait til tomorrow to change back.

As previously stated, you may have to change the kernel, because not all are compatible with it. And also when connecting, it can take 1-3 minutes before can "connect" with data when using the wireless tether/hotspot.

Found a solution to my problem here.

[Q] Wireless Tether issues

Anyone else having issues with wireless tethering? I have tried multiple ROMS including Random 3.3, CleanGB 1.0.3, and SleeperRom. The hotspot Hack used to work brilliantly for me but about a week ago I started having issues where my ipad would connect for about 5 minutes on first start of the tethering, then after about 3-5 mins it would start flashing the connected icon (like it was connecting and disconnecting from the hotspot). Other wifi connections work just fine (example the one at my house).
I have also tried barnacle and wifi-tether beta 11 for root. Those don't seem to be able to connect at all. (Could not join network message for barnacle, connect briefly then disconnect for wifi tether)
Any help is greatly appreciated as I use the tether to watch hulu and netflix while at work and I have been bored the past few days.

Since it is on every ROM and every tether app, is it possible it is something in your Ipad? Never had a problem tethering from Froyo to CM7. Try Odining back to stock, root and tether. If it works there move forward testing at each stage. You may have bad data somewhere.

I thought it might have been the iPad also except that all the other wifi connections I have tried work like a charm and stay connected. I am at stock EI22 right now so I will get it rooted and try again to see what happens.
Are there any system logs or anything I can look at to see if the broadcast is going in and out or something on the epic?

You can try running logcat. It is an app in the market. It logs all operations.

Might have resolved it...
I did a clean ODIN back to stock EC05, then ODIN to a rooted EC05, then ODIN the CWM 5.
I flashed CleanGB 1.0.5 MTD and attempted to tether with default settings (enabling security) which i think defaults to WPA Tkip. that didnt work (connect then immediate disconnect then when I attempted to connect again it gave failed to join message.)
Finally I switched security to WPA2 AES and connected the iPad. it has been connected for a few minutes now so hopefully it stays connected.
Thanks for the help.
TLDR: Switch security on Hotspot Hack to WPA AES and tether worked.

Nice job! Glad you got it working.

[Q] No internet through WiFi after few minutes, still connected

Hi guys,
I've searched the whole forum but I couldn't find any other thread about my problem.
When I connect my HOX to WiIF (Sitecom WL-370 - 300N Gigabit Dualband Router) everything works fine at first, but after a few minutes (5, or sometimes 15 minutes) I've got no Internet anymore but I'm still connected. Also WiFI Analyzer still detects the network. I've this problem both on 2.4 GHz as on 5 GHz. I've also tried switching channels.
The strange thing is, I can still receive a WhatsApp message but I can't send any, also I can't browse on the Internet or things like that.
After turning my WiFi off and on it works fine again for the few minutes..
Best Wi-Fi performance is turned on and the other devices at home haven't got this problem.
Anyone having the same problem or knows a solution?

I've got the same problem and it seems to be totally random. What i noticed is that my Google Play Store always stops working (no connection) shortly after i turned on the phone (~10 minutes). Switching Wifi off and on again doesn't seem to change it, i need to restart my HOX to get it working again while other apps connect just fine after turning Wifi off and on again.
Edit: Stock Vodafone ROM (1.28.161.9)

I have the exact same issue and i went through every setting in my router trying to fix this.
I would turn on my WIFI, connect to my home network, and start downloading. After a few minutes it'll either stop (the dl percentage not change) and then if i reload the market/youtube/browser or any app that users the net, it'll say no connection.
The weird thing about this is that it LOOKS like i am connected to wifi (in the notification bar).
This may be a separate issue, but i tried to turn it off and then on again to get around the issue. This time around i would try to connect to my home wifi and it'll just say 'Saved' and then the network would go out of range.
I am running Leedroids rom.

I might have found a solution:
Under Settings -> Wifi -> Menu -> Extended there is an option for Wifi Power Saving. After unchecking it all my connectivity problems are gone.

May be worth trying a static IP configuration, if you know enough about ip4 to do it. I've seen problems with android Wi-Fi since version 2.2 - if your router issues an indefinite dhcp lease, it can show exactly the symptoms you describe. Only a possibility but worth a try.

I have the exact same issue - the wireless shows connected yet you cannot browse the Internet etc. I have also tried every setting on the Wireless AP without any success. Even tried static IP and that does not fix it either. Whilst other devices in the house are ok...
The weirdest thing is though it does not happen everywhere i.e. at other places like work (where at least the same type of AP is in use) or at my brothers' house (where he has a Linksys). This is pretty much the only thing that bugs me with the HTC - the only workaround I have found is to make sure that WiFi is kept on only at times when plugged in - this doesn't actually fix the issue but it does mean that the phone will disconnect the WiFi and get a new connection next time it wakes up - this way I find I get the problem much less than when I have it set to Always.

Yeah, exactly, I've got the same problem. At school I've got no problems with the WiFi. I already send a message to HTC and I'm waiting on there answer.

I have kinda the same issue.
Using a HOX and at work I'm connected to Wifi and I can browse. At my house I can connect to the wifi, my IP is right that I'm getting from DHCP (I even tried putting in a static IP) but I can't browse
I also have a HTC Sensation, same setup and it works. The sensation can browse at work and at my house.
Why would this be?

Tried all sorts of solutions, but the only one that works is disabling the N-band and only leave B and G. This means that your laptop won't connect with the faster N, but at least the HOX works (what's more important )

Well I tried broadcasting a separate SSID on the b/g interface only for the exclusive use for the hox but that hasn't made any difference...my workaround is to have tunein radio in the background streaming whilst surfing...if I get bored of that solution my next workaround will be to trade the hox for an s3 as much as I despise TW...

I tried all the bands "B, G, N" and nothing works. So tired of this crap. Think I might just get a S3

I was thinking to do the same but there is no chance in hell of me doing that after I compared my HOX with a display model at the phone shop. Pentile screen vs LCD on the HOX? HOX = Sharper and better whites - the white on the S3 is bluish and so obvious. Another thing also I noticed is that the aggressive auto brightness on the S3 is too much - you won't tolerate it and you will likely be forced to manually adjust all the time. That plus reading that the S3 goes through the battery like no mans business when on standby unless you turn off all the features and put it in power save mode (might as well buy a Nokia then) at least the HOX uses the Ninja core and actually does save your battery in standby mode.
Anyway - the reason I replied is that I found a workaround (note, workaround does not mean a fix) - I put in a wifi extender in an area where I tend to spent most of my time with the HOX - this has not fixed the problem per se but rather seems to have elevated it somewhat. Basically now if the HOX drops from the main offending AP it automatically gets hooked up on to the extender and carries on working! I say this because (and I saw this only twice so far) I realised that when the phones Internet connection stops and you load a new page it timed out and get page cannot be found but when I hit refresh it works again you do notice a 3-4 second lag (this never happened before the extender came into play). Not sure if anyone else has tried this but I got a Linksys/Cisco extender for £69 and so far at least it has given me a workaround. Of course your mileage may vary...so don't splash out on an extender and come and blame me if it doesn't work for anyone here...

I am also having this issue with my HOX has anyone found a fix for this?
i have tried everything listed and nothing works.
its weird though because i have NO issues on my home network, but my network in my apartment here and at work network i get this issue

!!
bbbbbbbbbbbbbbbbuuuuuummp any fixes??? this sucks !!!!

What versions of android you guys have? Stock, sense, vanilla android, ics, jelly bean? Because I didn't encounter this problem when running stock or ics custom roms. After I updated hboot to 1.31 and tried different jelly bean sense roms it appeared. I also tried some stock android roms (ice cold jelly and liquid smooth) and wifi seemed to work fine. So is this sense problem only?

[Q] Push notifications delayed on WIFI

I've seen a few similar threads to the one I'm about to make. I've tried different suggestions which I will post here. Yet, none of them seems to work and I'm curious to see if anyone of you has a fix for my problem. My phone is an unbranded international HOX using the 9.7.2 ARHD rom by Mike1986. Here we go:
Problem
While being on WIFI my push notifications aren't coming through in time. There's a delay from anywhere between a few minutes up to as much as 40+ minutes. The phone doesn't have this issue being on the mobile data network. I'm also not 100% sure if the delay is still there when I'm on an different router. Even when I turn on the screen again, the messages seem to come in randomly.
Settings
WIFI best performance enabled
Static IP by router
WIFI sleep policy: Wifi always on
Tried suggestions
Wakelock: One thread described using an app called REGPON keep-alive, which installs a wakelock onto the phone to keep the data connection alive. This app did not do the trick. It only drained my battery and the messages still didn't come through.
Wifi performance: Set the phone to maximum wifi performance. This seemed to work for a while but ended up not working proper either
Kernel: Try a different kernel was one suggestion. I've switched from Stock to Faux123 010 kernel. This didn't change anything about the WIFI problem.
Static IP + Portforwarding + Disabling router Firewall: I've tried both port forwarding on port 5228 and even the range 5224-5228. I've also tried setting up triggered ranges. Maybe I'm doing something wrong on this part though. The router firewall is disabled and it should no longer block anonymous WAN packages.
Disable SmartSync: With the Suite Tools that are included in Mike1986's rom I've disabled Smartsync. No results as far as the wifi problem goes.
Probing app: I've tried an app that supposedly probes my router at least every minute in order to keep the connection alive.
Switching between b/g/n network: Didn't make a difference. The signal quality of the router is also good.
The only thing that did work for extended periods of time was using this remote control app that allows me to type through my PC keyboard, where the text ended up on the phone. I've also got an app installed to test push notifications. It's capable of making a log. Maybe that'll give you guys more information.
Right now I'm not sure if it's an issue with the HOX or if my router somehow stops the traffic. I don't recall having this problem on my HTC Desire. Does anyone have anymore tips?
Thanks,
Zendio

No problem with Gmail push notification on Stock 2.17.401.2.
Yesterday I still was on ARHD 9.7.2, also there I never noticed any delay.
Edit: this complies to various wifi networks (@home, @office, @parents etc.)

I am so sorry to hear you are affected by this problem, but also happy someone else is experiencing the exact same thing as I am !!!
I have tried different solutions to no avail.
Would love to hear something on this topic !!

Also I should note, I don't have any kind of task killer installed.
In general use WIFI feels really fluid and responsive. I really have no idea what could cause these problems.

I hope so. My One S is experiencing the same thing. I've tried everything above. No luck. Some stuff is fairly critical that I get it as soon as it comes in. I might try getting ahold of a Nexus 4 and do some testing with its wifi, just to make sure it isn't a general Android problem.

What router do you have? My issue was any android device in the house. Turned out it was my router, I put a custom firmware on it and all my trouble have gone away. My friend has the WiFi issue on a virgin media superhub.

I have an Asus RT-N66U. Funny you should suggest that. I'd planned to throw Tomato on it tonight and see how that works out. I did some tests at my folks' and their router had the same results. It's some cheap Netgear thing. Not sure of the model at the mo. I'll post back with results. If not tonight, tomorrow some time.

No go
Well that was unsuccessful. Actually it slowed things down. With the default firmware I get notifications from the instant I press power to wake up my phone. With Tomato there was a second or so before I got them.
Time to try DD-WRT tonight to see if that does the same thing.

I have an rt-n56u so the older version of yours and I'm running the Asus wrt that is being made, its fixed all my problems and is awesome tbh.

Set Beacon mode power safe (BMPS) to 0 in WiFi ???.ini config file should resolve this problem.
Such ???.ini config file usually placed under /system/etc/wifi or /system/etc/firmware/wlan/prima/

[Q] losing wifi connectivity- full bars but all gray

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?

I'm not trying to threadjack here, but I just wanted to share my experiences.
I've been have the exact same thing happen to my phone (Nexus maguro). I've tried every JB rom I could find, several different kernels and my wifi eventually always goes grey on me. All network activities stop. I'm back on stock everything right now and it still happens.
It happens on my home wifi as well as work wifi.
I'm about to puttstock ICS on my phone and try that out for a couple days.
Anyway, good luck with your problems, i'm going to follow this thread in hopes you'll get a solution that may help me.
If I do figure anything out i'll post back.

seems that this is a topic that has been posted on a bit over time with no real single culprit or fix. I'll post back if I figure anything out... I know in the Cyanogen thread, I saw info that stated that the MAC address of the phone was changing and I'm going to try and determine if that is happening to mine.

I have the same issue. Sometimes even when i pick up the phone, if i look fast enough i see that the Wi-Fi bars weren't even there! Thats only 1 out of 5 times though. The other time its usually just grey bars. Sometimes it actually will click back and they'll flash to blue and grey 2-3 times and then go solid blue. Then sometimes like you, they'll stay grey. I've tried everything too...reverting to stock, Different kernels, ROMs, routers, static IP, 2.4 or 5ghz, full auto mode. The only fix that makes it a little more reliable, is using Wi-Fi PM Fast. But even that, is not reliable. I'd say its about 50% reliable then, for a huge sacrfice in battery life. For me i've noticed this started to happen with 4.2. Before that i never had a problem. All other devices though no problem. My Nexus 7 is just fine. But the galaxy nexus, no matter what router or where i am, the Wi-Fi is totally unreliable. For me, it happens within 2 minutes that it will disconnect most times. Then 1 in 10 times it'll be fine for 10 hours.
In all honesty, i've given up. Just come to deal with it. Use mobile networks when i'm not needing to download. I can download files and stream music just fine too. If there is traffic going through, it never disconnects. But when its just sitting there without traffic, it disconnects, or, loses connection to google servers i should say.

well that's not good to hear...

I installed stock 4.0.4 a couple days ago and have not had my wifi go grey on me yet.

yeah, I love Cyanogen so not willing to go back to stock... waiting for them to finish 10.1 and I guess I'll see how it behaves then.

Hi all,
Just to say that I have the same problem. I have been upgraded from ICS to 4.2 and nothing had happened but I had to downgrade to 4.1.1 (AOKP Build 4) due to other issues and after that I started notice the WiFi problem.
At first I thought it was when the screen went off, but I has happened with screen on too. I have to turn WiFi off and the back on to connect properly again, very annoying.
As I said I started noticing this after I downgraded, but then again, I had used AOKP 4.1.1 before without this issue. I think that it is time to change my phone :/

I'm on Muzzy 4.2.2 and I'm currently having the same problem. It's not a new problem since I remember having it months ago (disabled my phone's WiFi because I kept missing emails and other notifications - grew tired of dealing with it). I thought it was my router, so I swapped it with a newer one recently, but it carried forward (old router was TRENDnet Draft N and the new one is ASUS RT-N66U).
I would like to know how to properly troubleshoot this problem.

I'm glad I didnt have to create a thread for this. I have been facing this problem quite a lot. I can confirm that WiFi works absolutely fine until 4.1.2, whether it is stock or CM10 (I havent tried the other ROMs yet). I have faced this problem only from 4.2. It still exists on 4.2.2. Happens on all the ROMs I have tried till now including CM10.1 nightly as well as the stock factory image.
When the phone is sleeping, it seems to lose WiFi connectivity and when woken up, the WiFi bars is grey though it is full. If I am very lucky, it will turn blue automatically. Most of the times, I have to switch WiFi off and back on for it to connect properly.
Anyone knows the root cause for this? In case this has been discussed in any other thread?

have you posted this information over in any of the threads where the developers are working such as Cyanogen in an effort to bring this issue to the forefront for more visibility?

I have had those wifi problems with every android version and rom I had on my GNex as far as I can remember.
Sometimes it will be able to reconnect but sometimes I have to disable and re-enable wifi to get it back.
I too thought that it might have been my crappy router as I have had multiple problems with it over the years (some Linksys router).
This is really annoying because it won't receive any e-mails until I randomly decide to have a look at my phone. :/

trust me, I understand your frustration... some days, I can go almost all day without loosing wifi data throughput and other days it won't last 10 minutes without going to gray bars.
unfortunately, no one is sharing any fixes which tells me that no one has a good handle on the problem.

Same issue for me on stock Android 4.2.2. Leave WiFi on overnight and when I wake up its connected to WiFi but gray bars...

The update to 4.2.2 drivers have fixed all WiFi issues for me. For the first time since 4.1 I can now use WiFi optimization now. And WiFi is fully reliable.

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?

same thing happened to me on toroplus sourcery 5.1, after trying everything i could think of and talking to one of the devs, i finally did a fresh download of rom and gapps. wiped cache,wiped dalvik, factory reset, wipe system, deleted android folder off of storage then installed the fresh download of rom and gapps and its been working great for me since. hope this helps.

Can you elaborate on this? I've flashed 5 different modems and still get this problem... it happens to my cell service bars, as well. Would love to know what the cause is.

i just know ever since moving to a 4.2.2 kernel that has the 4.2.2 drivers my wifi has been stable. I know there was a post in the anarkia thread with the ak kernel that had the drivers. but i believe most any 4.2.2 kernel would have them implemented. i do have the newest bootloader and radio too. but i know as soon add i got the 4.2.2 drivers all issues were resolved wifi wise. of course i think if you have a 4.2.2 kennel you'll have them.

I'm looking forward to that update - I've been watching the Cyanogen threads for when I think the 10.1 has matured enough to become my daily driver... good to know you've had positive results!

Temporary solution
me facing same issues , Solution would be to use an app called wifi fixer by zanish-g1 from the play store ...
it worked for me !! :good:
