Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!
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.
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...

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.

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.

Both my data and WiFi have been acting very strange the past week. Both services will show me as connected but I will only get the upload arrow showing on each indicator and then sometimes the icons just go gray. It has been happening very often and I have changed both my ROM and kernel on clean installs and I still have the same issue. Any help would be appreciated.

I started a thread here on a topic where my wifi and signal bars turn gray and the phone doesn't have data connectivity any more. sometimes this happens a dozen or more times a day and sometimes once or twice.
one response in that thread indicated that 4.2.2 made a positive impact on the problem.
I've been searching for a definite fix for this data/WiFi issue to no avail. I'm not entirely sure of when this issue began to occur but my phone (Toroplus) constantly loses WiFi signal. By losing signal I mean WiFi will turn off and on all by itself. And yes, WiFi sleep policy is set to stay on always. This issue alone made me go back to stock only to find the WiFi issue is present there too. I've also ruled out my router as the culprit. Im suspecting this is a Google issue. By the way, I talked to a sprint store employee who owned a galaxy nexus and after a few minutes of playing with his phone, which was completely stock and never rooted, I noticed his WiFi connection would turn off and on all by itself too. Any insight from anyone with knowledge to this would be appreciated.
Wi-Fi optimization off. If that does not fix it, I dunno.

Thanks for the suggestion but that doesn't fix it. Are you not having this issue? What's your setup? What ROM do you use? I've basically used all of them and it never goes away. I'm thinking of going to the HTC One when it's released just in case it's a Samsung issue.
I have also experienced this problem, especially at work where the network uses some WPA Enterprise variant. I've digged through logcats and can't find the problem either. A few Google Code forum posts talk about a possible bug introduced by network adapter manufacturers, or wpa_supplicant configuration issues. Haven't found a workaround yet, so I had to go back to 4.1.2, which seems to be stable.

The more I read on this subject the more I come to realize this is not specific to a certain device. The only common denominator that jumps out at me is jellybean. Seems like the issue is with Google, not hardware. Sucks that such a basic feature is not reliable out of the box. At least now I can understand why my buddy calls Android "buggy". Hopefully this is fixed sometime in the near future.
This is strange, my wifi works but then suddenly it only uploads (only green arrow lights up) and it will not download (orange arrow will not light up). I can disconnect and reconnect and I get some service, but then nothing happens.
I've tried the following:
Rebooting the phone several times
Restarting the router
Changing from DHCP to Static IP
Turning off the new open network notification
Clearing data from Google Play store
Disabled wifi power save with *#0011#
Nothing seems to fix it. What is going on?
READ BEFORE YOU FOLLOW ANY OF MY INSTRUCTIONS!! U HAVE BEEN WARNED I AM NOT RESPONSIBLE IF YOU SOMEHOW DAMAGE YOUR PHONE!!!
OK so let's go straight to Ur answer.... Let it sit for a while after it boots up (a minute) with Ur wifi on. so restart the phone while wifi is on and let it sit for a while... If Ur using a wired connection with a wireless router disconnect the wired modem then the wireless and wait 10 secs and reconnect the wired first and let's all the lights go green or whatever color they show u its ready and then connect the wireless router and try to connect to it.
If that didn't work and you don't have your phone rooted then flash the only time that we have for now. That should fix the wifi issue.
If it doesn't work try to go back to stock and let it sit for a while without touching it and if it doesn't work then the phones defective but keep in mind that if you went through the root process that if you send it back without erasing the flash counter your warranty will be voided so be aware of it. I don't know if there's an app compatible with the s4 so if it's not rooted then replace it just to be safe.... It's your choice

My phone is not rooted.
What did you mean by flashing the time?
How do I erase the flash count if I decide to root later?
Thank you for your help. =)
------edit------
The method -- sans the flashing the time -- seemed to work, but then the internet stalled again. This is happening on two S4 phones. My other phones have no trouble with the wifi, my pcs have no trouble with the wifi. What are the odds that two phones aren't working? Nobody else is having this problem?
I have already made a thread with the sane issue. You're not the only one facing it. A lot more people are too. It might be a software thing and might be fixed in the next update. If not, exchange it

What router are you using? D-Link DIR-655 seems to be most popular one people are having trouble with. What mode are you using (a/b/g/n/mixed/etc)? Mine only works with Mixed n and g mode. When you turn off the wifi, does it actually turn off (the green indicator will dim but should actually go away when it's off)? The stock rom seems to want to keep the wifi on at all costs... not sure why! Mine is very stubborn and takes several tries before it actually turns off and says "turn wifi on the see available networks." In order for the *#0011# Power Save Mode Off setting to work, the WiFi needs to actually turn off then back on. I have to toggle airplane mode sometimes just to get the wifi to turn off.
DGL-4500 Linksys
It shuts off when I save; I put the settings as you suggested. I'll test it.

DGL-4500 is a D-Link, correct? If it is a D-Link, I'd make sure you are on the latest firmware for it and try various mode settings (disable mixed modes, 2.4GHz or 5GHz only, WPA2/TKIP only, etc). This post details a solution to my scenario; maybe it'll give you some ideas.
I have d-link router too and wifi working just fine

Yeah, it is a D-Link; not a Linksys. I tried what you did, it seems to be okay so far. I have the latest firmware. I still think this is a problem with the phone. Do you think an update will fix it?

Yes, it's definitely a problem with the phone. I've spent the last several days researching and trying to find a permanent solution. It appears to be a software issue but I've yet to explain how wifi works just fine for some and not for others.
Any solution to this yet without messing with the router setting. I have this week left to get a full refund. I doubt exchanging it would make a difference. Plus tmobile is out of stock and stores won't allow exchanges since I bought mine online.

I sent my phone to Samsung, so I'm waiting to hear back from them on what they have to do to fix my issue. Maybe it's a faulty batch of Broadcom chips?

Thanks for the reply. Hopefully it can be fixed. I have 4 days left to return so I will return it for now and buy it later if it gets fixed. Let us know how it goes.

Has anyone heard anything on this? I got a PM from Samsung asking me some questions, but they never got back to me. Any news?
