[Q] wifi "avoided poor internet connection", screeoff kills connection

im trying for a week now to get around an issue that is costing me my nerves and renders my phone useless, especially on travel without roaming and data-plan. after screenoff my nexus kills the wifi connection, after some time though, 30 minutes, 1 hour, it seems to change. my company uses skype as the primary means to communitate and i'm just cut off, won't receive important mails, messages, whatever.
when i switch my phone back on wifi starts up again, if im quick enough the settings reveal "avoided poor internet connection" in the hotspots status. so basically it looses the signal for a moment and is not able to connect back on its own. i read 4.0.1 had a setting to circumvent that but since 4.0.2 it's gone. of course keep-alive-during-sleep is checked to "always" in the settings and i tried just about anything, changing basebands, factory resets, cache wipe, etc. nothing helped. the weirdest thing i that the battery stats to not reflect it, the blue wifi line is uninterrupted all the way.
i searched and found dozens of people complaining about this but no solution anywhere. they switched phones and had the same problems still. from little fragments i collected it seems that samsung devices had this issue before, cm7 supposedly fixed a hardware driver that had issues with certain wifi devices on certain frequencies.
im on AOKP b27 now (powersaver on or off with setting to untouched or "leave on" made no difference), leankernel, xxkl1 baseband. today i went back to stock 4.0.2 to see if that does something. still, has anyone here similar problems and maybe even solutions? what about the cyanogens "nexus one sleep fix" i read about, anyone can provide links or informations?

Did you try settings - wifi - menu - advanced - keep wifi on during sleep - always

Try changing that setting. I know 2.x defaulted to turn wifi off during sleep but I thought they changed that in ICS. Either way that sounds like the problem.

its not that setting, it's the first thing i checked. it's set to "always" and it should never kill wifi in theory. from what i have read by now it seems more of a wider problem, a software or hardware related issue affecting all nexus devices. most people don't know about it since it only fails for certain routers having certain settings (which other phones digest without problems though). i also never knew it until i had to stay one month in a place with a wifi-hotspot my phone doesn't like. my gf's s2 has no problems at all, neither have our laptops.
here on xda people have switched their devices because of that problem, got new ones and the problem persisted. i have installed roms, kernels, stock-images, basebands, nothing helped and i am sure the problem won't go away if i exchange the device. i knew i'd probably not gain much by asking again, threads like this can be found here, on rootzwiki, google, etc., but i was hoping to gather a little more knowledge. to read about cm7's patch for a similar issue on the nexus one gave me hope that something must be out there ...
btw, stock ICS seems to have the best reception by now, it stays connected for hours. but once it looses it, it won't re-connect aswell. my experiences are worse with AOKP. and it sucks because i love that rom so much. i guess when i'm home again it wont bother me since my own wifi is okay - but man, here, in another country it really hits me.

i had the same problem, seems like the connection would drop when the wifi signal is weak regardless of what settings you choose. i saw this problem on 4.01 and 4.02 stock, and apex rom. i had to switch to a router that could broadcast a stronger signal. i would get about 80-90 dbm with the old router and the new gone give 60-70 dbm. it seemed to have fixed the problem, i havent seen my gnex drop the wifi since i got the new router a few weeks ago.

Ive heard some people have a bug with wifi sleep policy setting not working. But mine seems to actually work. Set to "never" is the best choice and after hours of screen off my wifi is still connected.
Maybe try that setting a few times to kill the bug.

“never"should actually kill wifi immediately after screen off I think. If it doesn't that would be just another bug. I read somewhere that for some people setting it to never resolved the issue but i tried pretty much every setting by now, nothing worked out though. I became so desperate I installed wifi monitor apps that reset wifi after they figure it got dropped, but not even these patches could revive it in some occasions. The only thing that works for sure is switching on the screen every now and then.

It's a wifi sleep policy. So never = never sleep.

Weird, mine says "keep wifi alive during sleep": always, when plugged in, never. our I miss something and there's another setting I haven't tried yet.

this may fix ur problem... for rooted phone

How do you get that? It says "Keep Wi-Fi on during sleep", which implies "never" would always keep the Wi-Fi off during sleep.

[WIFI] Browsing works, market etc doesn't

Hello everyone,
My phone is doing good so far, i have some of the known bugs, but i'm very satisfied!!
But.... when i'm connected with wifi at home or at my gf's home (different locations, different hardware) I can use my browser but I can't use Market, Zedge etc. I'm a system administrator, so I already checked everything network-related that could cause the problem(Encryption, channel, toggle between g/n, ports). My HD2 doesnt have any problems.
Is there something changed on the HOX in how it handles a wifi connection?
Like to hear your ideas and suggestions!!

Mine is currently connected via wifi, and was also connected using the Mobile Network, and have had no market/email/browsing issues on any of those. Have you done any modifications on it? Are there any port lockdowns on those wifi signals you've been using?

The phone is still out-of-the-box. I only installed whatsapp and a few apps but nothing big.
I tried it with no security at all, port 5228 UDP/TCP are open, tried a different router.. no luck so far!

No such problems here.

I have the same problem with all Android devices. Enable the Data and connect to Market once (Accept the terms and conditions). Once Market authenticates then it should work with WiFi. I have spend hours trying to find out the cause but no luck. I tried to DMZ the router to make sure there is no Port being blocked. In case you find out let me know how you fixed it.

just make sure the date and time is ok

Posted the following in another thread but thought it would be worth posting in here:
Might sound strange, but try rebooting the router. I was having problems with my One X, almost the same issue as you. My HTC Sensation would be fine and my Galaxy S and my laptop also fine, but my One X would have terrible WiFi performance, even tried deleting the wifi settings and re-connecting, and also a factory reset, to no avail. At this point i was ready to take it back as I thought it was faulty.
As a last desperate attempt i rebooted the router (unplugged it for 10 seconds then plugged it back in), and my One X has been perfect ever since. Doesn't quite make sense why one device but not others would have a problem, but worked for me anyway!

I've actually had a similar issue, in that TuneIn kept refusing to stream, even after restarting the phone. Power-cycling the router fixed it, although other devices on the same network were having no problems.

Ok, Im starting to think this phone is killing my WiFi network.. having ip issues with all my laptops now everything is set to static now so lets wait and see..

Wifi dropouts

Is anyone else having sporadic issues with wifi on the One X?
I have two One X's, both running T-mob rom 1.26.110.5.
Wifi will work fine for some hours, then problems start. I usually notice this when returning to the browser - where the progress bar sticks at about 10% and goes no further in downloading a page.
This can happen to either of my One X's. At the same time, my other One X and both of my HTC Desires will continue to operate perfectly on Wifi. This situation can continue for quite some time, and usually I have to cycle the wifi power on the offending phone, whereupon that phone will connect fine again.
The good connection has lasted anywhere between 2 minutes to several hours.
This is intensely frustrating. When I got both phones home new the other day, I set one phone up first, and later in the evening first experienced this wifi problem. Thinking the phone had a fault, I continued and set up the second phone. But that also exhibited the same fault.
Note that all the time this is happening, I have 2 laptops, 3 other phones (included the other One X), and a media streamer, all connecting just fine to my same wifi access point. I doubt the access point is at fault - it has worked for years with the other equipment without issue.
Only the two One X's have intermittent problems connecting to it, and then not both at the same time.
So does anyone else experience this?

Are you serious? WiFi without password is an absolutely NoGo. I contacted today hTc with this problem. They said they know this problem, many users have reported it. They said to me I should let exchange my phone by my provider. That was not the the answer that I wanted to hear, but I hope they can fix it with a patch and it's not an hardware issue. But if you say deactivating the wifi password can temporaly fix this problem, it should be possible to fix it with an software patch.

I was having wifi problems as well and had lots of other devices which connected just fine. I reset the router and it seems to be going well...
Couldn't try it on another router to see if the router was the problem or it was the phone.
Otherwise love my new one x!!! YAYYY!

Got the same Problem. I just signed the device a fixed ip in the Router config and have no Problem since...
Maybe u should try some like that.

I have noticed WiFi drop outs. Have assigned a static ip, testing to see if it makes a difference

Mod or Die

Mine was showing the loop on connecting, authenticating, obtaining ip. That is a common problem in Android (and nowhere else), but I worked around it by connecting to a different router, then re-connecting to my own router. (In addition to all the other rebooting router, rebooting phone, rebooting refrigerator suggestions). Yup, static IP too. Still would get the problem.
Tracked it thru alogcat and can see the exact point of failure, but still cant fix it.
BUT IT GETS WORSE: My phone stopped scanning. It can't find ANY routers.
If you manually enter a hotspot it shows as not in range.

Mine is getting a little better with static ip and improved wifi performance ticked, but the issue is still here.

UPDATE:
Rebooting the phone didn't help. (It would still not scan for routers)
In Power Settings, there is a checkbox called FAST BOOT.
It came from the factory checked.
I unchecked it and now wifi scanning works again.
I still get the connecting, authenticating, obtaining IP Loop, on some routers. Rebooting the router will solve that as a temporary fix.
There is also a setting called Best Wifi Performance, which some suggest keeps the wifi chip from entering a deep sleep mode, making wake up faster. I checked that too.
Still not happy with the wifi problems. (no, its not my router, 7 other android devices connect to it just fine. Laptops and printers also).

Thats exactly what I found out too. Therefore it would be necessary to give the One X a own IP but in its own config. Not only on the router.
Do you know if this cn be done?

[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 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.

[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 running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?

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

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:
