I am using Verizon GS4.
Actually, I go to Columbia, but my GS4 keeps disconnecting and reconnecting immediately the wifi that Columbia provides.
Other devices have no such problem, and my GS4 does not have the same problem with other wifi networks.
I searched for relevant information on google so much, but nothing worked.
Could you guys help me identify what causes the problem and solve it?
Thank you.

Well, for starters you'll need to provide more information, such as
is this a dev edition or regular verizon phone?
are you running a custom ROM and/or kernel?
can you use other wifi networks?
I've never had any issues with mine.
Mine is just a regular verizon phone and I don't root it.
With other wifi networks, there are no such problem.
Columbia provides two wifi networks: one is unsecured, the other is secured.
But, both of them have the same disconnecting and reconnecting problem.
Actually, I even got replacement from Verizon, but the replacement one also has the same problem.
Of course I did the factory reset, which did not work.

Sounds like some compatibility issue with the access points AFAIK. I know there were some initial issues with some DLink consumer routers but this would be something new. You might want to see if you can find any information on the access points and report to Verizon/Samsung. For that matter you might report the issue to folks at Columbia and they might be of help.
That said, perhaps someone else has seen this and will chip in.
You are probably connected with DHCP. Sometimes I have found it useful to go into advanced options, and then click on "static". You should then see your IP address that DHCP has automatically assigned you. Try changing it and connecting. For example, if your IP is 192.168.0.7, try changing it to 192.168.0.45 or a number higher up.
Some of the routers have issues automatically assigning IP's. And with all of the connecting/reconnecting, the lower IP addresses can have issues. Assigning yourself an IP address that is out of the normal range that most connect in, can sometime help. My router at work does the same thing. So I set it up with an IP that was way out of range. 192.168.0.210. The DHCP service the router offers rarely assigns addresses in that range.
Also, sometime others will have done this already and assigned themselves a static IP in the low range. And sometimes the router will give seniority to someone connecting statically or that already has an IP or MAC that is filtered either on purpose or accidentally from an old configuration or user.
There are many scenarios. Including device fault. There could also be issues with the two routers or single router that is emitting both a secure and insecure connection.
Try the static IP address first, then report back.

It's likely to do with the WiFi Multimedia or equivalent in your router. It is especially prevalent in the Dlink DIR-655 and DIR-855 routers. If you have an "N" rated router (everyone should have) if you uncheck WMM (WiFi Multimedia) in your advanced router settings and reboot your router, you should not have any more constant connects or disconnects.
Sammy blames the hardware manufactures and the manufactures blames Sammy with each others firmware as the problem. I was using a DIR-655 router until i just updated mine last week to a Linksys EA4500 (N900) and no problems at all.
Just so you know, unchecking WMM means you force the router to basically run at "G" speeds instead of "N" speeds. WMM was a workaround compatibility fix during the time when "N" speeds were still in draft status, not official. New routers still use WMM but its all stable and new routers shouldn't have the same issues with the GS4.
90% of the time this is the exact issue people have with the constant disconnects with the GS4 with their routers. The fact it is at a university means you likely won't be able to fix it. You can try seeing if they can test this theory at their IT department but I have no clue if they will do it.
solved
I just set "Static IP" in the advanced option without changing IP address.
But, this solved my problem, thank you for your help especially h311sdr0id.

So since updating my atrix 4g to av 2.3.6 b 4.5.141 update my home wifi connectionto the device has been turning on and off. I have narrowed it down to the router belkin g+ mimo just wanted to make others aware. Had no issue before this update.
Any info on why this has happened?
All other devices stay connected as usual.
The Radio that comes with 4.5.141 is 1.77.37P, which I am also running and has given me the same problem. My former radio (1.77.30P) that shipped with 4.5.91 did not have this issue for me.
I fixed it by doing the following:
Settings > Wireless & Network Settings > Wifi Settings
From there, hit the menu button and choose advanced.
Click the "WiFi Sleep Policy" and set it to Never
This will stop the wireless from shutting off when the screen is off. Hope it helps!
Did you power off/on both the router and phone? Always worth a try before spending too much time do other possible fixes .
If the sleep policy is already set to never and you're still experiencing the problem you could:
1) flash the older radio
2) debug the problem. Install the sendlog app in marketplace. Recreate the behavior a few times. Open sendLog and email it to yourself. Look at the sendlog output to see why your phone is dropping the connection (wifi auth errors, signal issues, etc).
My home wifi is an old WRT54GS with WPA2 PSK and I've had no problems. Work is a 802.1x EAP. The other day I was at a coffee shop that had WPA2 and my Atrix was having some issues authenticating with the wifi router. After a few tries the phone finally connected. Not sure if that's the same problem you're experiencing.
Thanks I tried that.
What is happening is the connection just drops ff while on web or youtube ect.
It disconnects for a sec then reconnects. does this randomly. Even with the setting to never still randomly disconnects and reconnects.
Like I said no other wireless device does this and the atrix just started after the update.
may have to change routers hope not.
Will try the log app and post the results later.
Why change your router when it's the phone that has the problem? You need to address the root cause, not try and bandaid it.
Any possibility you can flash the 36P radio and try that? (Need to unlock your bootloader though).
Could also try a hard reset (30/30/30) of your router. This will load back all defaults, and sometimes clears up connection issues if you have them, but since this started with the update, it shouldn't be that.
I dug out my old netgear. atrix hasnt dropped connection once.
Something here conflicting with the belkin making the atrix drop it.
Tried the log file. Lol 1.2 mb of confusion.
Thanks everyone.
Maybe get belkin to send me a new router.
Just for testing purposes can you try connecting to the belkin with no WEP/WPA/WPA2/whatever enabled?
btw don't post sendlog output. log could contain sensitive information .
Its a known issue on Belkin routers and the 2.3.6 gingerbread update. Something to do with DHCP Lease renewal. Try this
Go in to router settings
Select LAN Settings
Change Lease time from forever to 2 days
Reboot router and phone
This fixed the problem for me
Sent from my MB860 using Tapatalk
I resolved the problem. Belkin rep explained to me that I need the N band.
I was using G the new update for the atrix updated the radio. My router was old and the firmware is outdated. Sounds like bs to me. Anyway bought a linksys today. Problem solved.
I was impatient. Will try changing the date just for giggles. For now Im surfing xda.
Edit: changing the lease time did not resolve the issue for me. The new router is working perfectly.
we have a Belkin 750DB, and a Netgear WNDR3300 and are experiencing the same issues on the belkin, but not the netgear. I haven't had a chance to try the difference between N and G on the belkin. We haven't found a resolution yet, the router is only a few months old, and costs way too much to change out... any else solved this really yet? besides falling back to the 36P radio?
I run a Netgear on G and another Netgear on N at home, and have no problems with either router with any radio. My network printer runs off the G network, so I switch the Atrix to that if I need to print, otherwise my Atrix connects to the N router.
(Split the G and N so I can run N devices only on one and maintain highest transfer speeds).
I think the sales guy was talking BS. Atrix works fine on either band.
..
Just a update on this...
I have tested Netgear, and Linksys routers
Both have performed flawless
It is only on the Belkin router that the issue occurs at least for me.
So it must be some conflict with the new radio and Belkin.
If anyone has had luck with Belkin please let me know your settings.
Had problem connecting my Droid Razr Maxx to my router at home (Netgear wndr 3300) but it connect almost everwhere else. After much help, and great service from Verizon and Motorola, including a next day replacement from Motorola, I found the problem was probably a conflict with the IP addresses i was using on the router. There is a conflice with base address 192.168.20.1 if it is used. You get connected, get an IP address but do not get any data. Changed to 192.168.0.1, and it worked fine. Have 192.168.16.1 at office it also works fine. Seem sot be conflict with LTE IF address. Love the Droid Razr Maxx. wonderful battery life.
From my experience, I have found that power cycling the router will in most cases resolve connectivity issues like this. But obviously that only works if you have access to said router.
On a side note, how exactly did you successfully perform a battery pull if you say you own a Maxx
I believe it has to do with what frequency range the router is using. I have a very nice VPN Linksys at my parents that I let them keep and it has the same issue with razr, thunderbolt, and Gnex so far. However my moms incredible 2 connects just fine.
I believe if you change it to a more common (off the top of my head, 90mhz) range everything should be just fine. I remember reading this somewhere and it made since, but my expertise is not in networking.
I haven't actually tried the fix because well, its my parents house and they have unlimited data and barely use 0.4 gb a month so no real need.
Hope this helps
Edit: I run a net gear at my house with 9-12 devices on it at a time and there are no issues connecting.
Sent from my Samsung Galaxy Nexus - Verizon 4G LTE.
When I had this problem I set up the router as no security, did not correct problem. Set up as 2,4 only no security, did not work. set up as all individual channels, did not work. Obviously powered down router and power up with each new setting, Still did not work. Even rebooted phone each time. Only thing that worked was changing base address. Did not remove battery.
Only question I have is if i run into a wifi network with this base address and I can't change it, I'm out of network connectivity.

WIFI problem
OKay... but how do you fix the wifi problem if you can't access the router? My droid razr maxx is having wifi connectivity problems with the wifi at my school. The phone will connect with the wifi for about 3 minutes, disconnect, and reconnect in an endless cycle. This sucks because I just got the phone a few days ago. I had a droid charge and never had a wifi issue like this. Any suggestions or solutions would be greatly appreciated. If I can't get this resolved within a few days I'm going to exchange my phone i hope that something will change.
wifi issues
I have 2 wifi routers at home. My RAZR could only connect to my 802.11N router and not my 802.11G router. It sees but when I try to log on to it, it would not connect.
So, it all depends on the router. It will see the signals from the routers but if it is not the N router, it will not connect.
I hope this helps.

Thanks for this! I had two friends whose LTE phones could connect to my home wifi but did not have Internet access. My Linksys WRT54GL running Tomato 1.28 firmware was configured to the 192.168.20.xxx network. Just changed the subnet to .15 and their phones now work on my wifi.
Seems silly to me that LTE network would have a hard coded conflict with a class C private network address. They should have used a much less commonly seen class A network if it is necessary. Regardless, thanks for the solution!
why do all you guys have your subnets set so high? standard is 192.168.1.1 on linksys, the highest I've ever had to move it to was 192.168.3.1 due to neighboring linksys routers.
Side note, I don't know if this holds true for all android devices, and may be more hassle then its worth but I've read on the samsung galaxy player pages of someone with wifi issues to his belkin router and he solved it by setting a static IP for his player, maybe you could try that with your razr and see if it helps.
@bryan how is tomato? I use DD-wrt on ALL the routers I can flash it to and is why I haven't paid to have internet at my house in like a year and a half (weekend rental house across the street).

I also want to pass on my thanks STEVEAPSEY, The only way to get my Droid Razor to work on my (Belkin) WiFi was setting up a public connection. I was leaning towards protocol settings but did not want to disrupt (and redo) all the other devices hooked to to it. In hind site public does give out a different IP! Well done!

Recently picked up a gs3 and I like it but one thing that is really bothering me is I'm getting constant drop outs on wi-fi and the reception is very low unless I'm standing next to the router.
Other devices do not have any issue at all. I've also noticed when scanning wifi the gs3 doesn't pick up as many routers as other devices do.
I've been reading threads and noticed a member mention going into the service menu and disabling power saving on wi-fi but that has not solved the issue.
I'm wondering whether it's a hardware or software problem. If it was software then surely others would have issues?
I don't really want to exchange the phone incase I get screen issues like the pink tint or blobs people are having.
But obviously if I have a hardware fault then I'll have to get it exchanged as a phone that keeps disconnecting from the wifi is not useful to me.
I also have this problem but it also extends to my 3G connection. Does not connect until I restart my phone, doesn't happen often, but its a pain when it does. I downloaded a WiFi fix from Google play and so far so good not had any problems...this is the only problem I have with this device otherwise its a beast of a phone.
Not sure if your setup is like mine but i had two routers in my home broadcasting the same ssid and channel. I kept facing frequent dropouts until i changed the channel on one of them. It seems the device kept bouncing between the two routers even though i was much closer to one. No more drops once they both broadcast on different channels
i read somewhere in this forum that you have to change the setting of the band of the router to 5ghz.
that fixed the connection dropout of wifi.

Thanks for all the replies
Just to update the thread, since I started this thread my wifi has been awful the way it keeps disconnecting especially when downloading large files.
I've been googling and had tried lots of different things.
What finally seems to have solved the drop out issue is turning security on my router to wpa instead of wpa2.
No drop outs so far even when downloading large files, but the signal strength is really bad, not sure if I still have a hardware fault or whether the galaxy s3 wifi is just weak.
Hi,
Same problem with mine. weak signal. At home or at work.
I think this an issue (hardware ? software ?).
But I'am surprised that we are alone.
Me too
Same issue here with regular random wifi dropouts at 2 ap's. Radio streams far more reliably over 3g!

i found this thread on xda, i'm hoping it does the trick
If you are using 2 APs with the same SSID and settings, your device can roam seamlessly only if the underlying network is the same network. If the 2 APs connect to different network subnet, it will never be seamless and you will get connection drops.
Your device must receive the same IP and subnet from the same DHCP with same gateway so it will be seamless between 2 APs.
I had issues at work. But not at home.
Today I told it to forget my B/G radio and to connect to the N radio. No disconnects, none..
No changes made to the phone at all..
May not be router
Hi, for what it's worth, my husband and I each have an s3. Mine has no problems at all with wifi anywhere. His drops out at home. I posted more here: http://forum.xda-developers.com/showthread.php?p=28510251#post28510251
We've tried the *#0011# trick and that is a temporary fix, but we need to redo it on a regular basis. The setting is not saving.
Update, I've had my phone replaced by Samsung tech in Plano TX, that doesn't help, but updating my router to the Apr 2012 eko dd-wrt did make some differences. Also the ota update from att has a new modem apk and that also chg'd the phone functionality. One thing that I have seen is that the phone reports the wifi network signal as being lower than before, and the output signal is slightly higher. I find that I have to occasionally turn the wifi on and off to reset it.
Short list of fixes and things to try:
1 update routers firmware
2 no dual encryption
3 some routers with 300 or greater Mbps settings need to be toned down to 150 or less
4 phone likes mixed protocol network over N only.
5 turn off phone power save
6 un check the carrier hot spot notify.
7 un check open wifi notify
8 pick a single band 2.4 or 5ghz. Note that updates with this can temporarily lock in to that frequency and not allow changes.
9. Dial *#0011# menu button, wifi and turn off the power save setting. This has to be done on every boot, and may cancel the display timeout.
10 On 5Ghz don't use DFS channels
Incorrect since people who have installed some roms and cm 10 are saying that they don't have any problems: I am almost certain now, that the wifi disconnect/connect issue is hardware incompatibility.
I have Linksys wrt-610 v2 -- which has problems
I have Netgear WHR3500L which has problems
I have Linksys wrt-54GL v1.1 which has NO problems (had to dig this out of storage)

I've posted this and then the mod's moved the thread http://forum.xda-developers.com/showthread.php?t=1722363&goto=newpost to the Sprint version of the forum.
Here's a recap since the guy has a sprint phone and won't recognize my issue there.
Here's the issue I've been having. I'm in a very active 2.4 wifi neighborhood. Even though I had the advanced wifi set to 'Always on' it kept disconnecting (and instantly reconnecting) to my network. The phone is scanning the neighborhood almost every 15 seconds. It's simply WPA-2 with just AES (and I'm not changing to TKIP)
This is a problem for me as I use "Unlock wtih WiFi" to keep from having to enter my PIN when I'm at work/home and "Home Sweet Home" which uploads any photos I have taken to my server when it detects the home wifi network (and deletes them from my phone after 3 months).
Anyway, I was just on the chat with Samsung and in the end we did this,
1. disable the ATT WIFI auto login function (seems there's something similar on the Sprint phones that's a issue).
2. soft reboot the phone (turn off, pull battery, count to 30, boot up)
However this suggested solution doesn't work.
The wifi isn't staying connected though the breaks are very very temporary, but long enough for those apps to kick in.
Update additional things tried:
3. Turned off WiFi power save in the *#0011# service menu
4. Turned off Open WiFi notifications, ATT Autologon.
5. Selected a single wifi band (5Ghz) where there is ONLY one network, mine
FWIW, I like that it connects to my 5Ghz wifi at 150 mbps, the speed is great.
6. I've disabled the Unlock with WiFi and it still occurred.
Here's a video of the issue showing the phone:
http://youtu.be/FBo3NFdcMhs
Here's a videoe of the issue showing the router: http://youtu.be/rRALDc8LZOk
and for those technically inclined here's a dump of the logs which clearly shows the drop and reconnect: https://dl.dropbox.com/u/38266113/SendLog.txt
FWIW. I just got off a 45 minute call with Samsung Help Support, went to level 3 support in Texas. This is newly documented, I've referenced this forum for additional reports of the dual encryption and the wifi connnect/reconnect issue I'm having. My ticket # 2113584507 (just for disconnect/reconnect) which you can mention at level 1 as having the same disconnect/connect issue. I specifically asked if I could post the ticket # so anyone could reference it at Level 1, but they will still take your own experience down.
Level 3 said they expect that they will be getting calls today since it's the first full day after the release. So if you want it fixed, CALL SAMSUNG, they're collecting bug reports.
I was having this same problem yesterday afternoon at work. Last night I set my radio to 5GHz only and today it hasn't happened once.
I am so glad I found this as it was driving me nuts on my new Sprint SIII. I think it's bouncing back and forth when both are available as at work, it stayed solid where we only have 2.4.
Thanks!!!!!!
I had that problem the entire time I had my Captivate. Very short disconnects. Only reason I knew was because of a task I was using in Tasker having problems, and I set a method to track connection.
I fixed the problem with setting a static IP address. I used WiFi Static.
I'm using it on the S3 just to be sure.
Had the same problem. However I set it to connect to 2.4ghz and it stopped doing that. If I put it on auto it will do it. If I leave at 5 it won't connect.
I do however think I might have a wifi dead spot. I notice if I hold it a certain way I lose a signal or two on wifi. Or the speed of wifi decreases. Anyone else having the same issue? It might just be me

I've experienced the same wifi drop issues so glad it is being investigated. Thanks to OP for diligence in tracking this down!

although I've gone to level 3, I need you and everyone else experiencing this to report it so that its corrected. Granted they are certainly going to visit the wifi code for the dual encryption issue and stability with Auto frequency, but fixing this could be done at the same time.
FWIW, since I have two routers and 3 networks, one of them is simply a pure G up to 54mbps default firmware setup (since it's the FCC's) and connecting to that greatly reduces but not entirely eliminates the problem (even in the same room). It's much worse on my "N" only networks. And I have tried static IP that also doesn't fix the problem. This is some sort of software issue in the renegotiable speed setting or timing settings or power savings. Off course it certainly could be some badly (or purposely) behaved app software too.

More likely to be a timing issue or protocol issues as the phone scans and tests various networks on different bands and protocols. Many people have n routers that do mixed networks, b, g and n, and they just may not know what they are doing all the time as the phone renegotiates with the router. I have a wrt 610v2 doing only n on 2.4/5ghz and on the the Netgear N300 it drops less doing 2.4 g and at my friends who have a wrt54g and it dropped even less often. The app that I use to enable my lock screen pin makes this more noticeable.

FWIW, I decided to followup on the ticket. Samsung level 1 (not that it matters) says they have never heard of this problem. Level 2 was better, and we in essence setup a new ticket with the videos already linked to it. I offered a sendlog, I offered to install a test app if they have one. I already beta test for a number of app developers as well as some major hardware OEMs.
PLEASE, everyone, call samsung support directly and register a ticket that this is a problem so that they have the information first hand and not via ATT or Sprint, etc which they might ignore.

I just called. They said they would note it 'on my account'. They indicated it would be a Google issue, not Samsung. They only do the hardware (and of course, it can't be a hardware issue, can it? )
I was thumbing through the phone logs from a boot to connection and reconnect. I have to say Chrome has a lot of errors thrown particularly in the bookmark sync. Also it appears that every time the wifi is initially started it checks for authentication for tethering on both the wifi and BT. It almost looks like the phone thinks that the wifi ap is off and restarts wifi scanning.

Which phone number did you call for Samsung support, please?
I have experienced the slow network and disconnect/reconnect issue on this phone since it arrived, but all is normal on our 5 or so other mobile devices with this Netgear WNDR3700 router on the 2.4GHz and 5GHz bands.
Oh, and there's this.

I got the EVO 4G LTE last friday and, while it worked great, I had it for about 2 days before I noticed that there was something under the screen. I returned it and got a new phone, but unfortunately the new phone had the Wifi / 3G connectivity issue that seems to be happening on some of these phones where both will cut out randomly and while the 3G is connected, it will often get speeds as low as 20kbit/s. So I took that one back also for a third new phone in 7 days, but unfortunately, this new one also has the exact same connectivity issues. I'm wondering if it really is the phone and I should return it again, or if its something else going on. As it stands, my 3G is next to useless in most parts of Denver where I live and my Wifi is only good if I don't need to use it for more than about 10 mins at a time. I should also point out that I don't think its my wireless router since my old phone is on wifi at the same time and it never waivers.
Thoughts?
Thanks
Have you tried this?

I'll give it a try, but I'm not sure I have the same problem, as it seems like the people with this problem experience almost no wifi connectivity at all due to the signal bouncing up and down. Mine just seems to disconnect once in while for a moment and then reconnect, but long enough to disconnect me from whatever I was using the net for (pandora, various games, store downloads). I hope this fixes it though, since I'm getting sick of replacing phones so often.
Well, this took all of 15 minutes to not work for me. Even with the wifi set to only 2.4GHz, it still disconnected. I guess I'm going to have to replace the phone again.
Have you tried power cycling the WIFI router? I had this problem before, but it seem to stop after I removed the power cord for about 1minute. Also, have you tried a different channel on the router. Depending on how close your neighbors are, you maybe getting interference from a nearby router.
I got mine on may 24th @ BB. Never had any issue other than a few lag moments. I run 5ghz and 2.4. Phone on 5ghz and 3g auto switch and NFC on and no issue. Still get over like 20+ hours moderate use.

My first phone worked great, but had the screen issue. Since then, its just been one bad phone after another... I'm on #5 now (#4 never even touched my hands as the salesperson noticed the same screen defect as my first while installing the screen protecter), and I've got a whole new problem where the upstream connection is much slower than the downstream and ends up getting stuck, with the only way to get it moving again being to turn off the 3G and then back on again.

I have indeed tried all of these things with no luck.
I'm debating on taking mine in because of a yellow spot in the middle of the screen .

Depending on your router configuration it might drop your phone from the LAN.
Instead of using DHCP from the router, set a static IP through the phone. There's a guide here. But to sum up:
First, go to Settings > Wifi and tell your phone to disconnect from your network if you're already connected to it.
Select your network once again from the list, and enter your password as usual.
Tick "Show advanced options" and some extra options will appear. Select "IP settings" and choose "Static" instead of "DHCP."
IP Address: The IP address you want to assign to your phone. This should normally be taken from the pool of IPs available for devices to claim via DHCP (check your router's admin page if in doubt). Usually something on the same subnet as your router will do. For example, if your router is 192.168.0.1, then 192.168.0.2 to 192.168.0.254 should be good.
Gateway: The IP address of your router, usually 192.168.0.1, 192.168.1.1 or 192.168.1.254.
Network prefix length: This is a different way of specifying your network's subnet mask (check a conversion table here). For most, the default "24" will work just fine.
DNS1/DNS2: Your ISP's primary and secondary DNS servers. If you're not sure, you can always use Google's public DNS service by entering 8.8.8.8 and 8.8.4.4, as we've done in our screenshots above.
Click "Connect" and you should be good to go!

Whenever there is a Wi-Fi problem, you HAVE to try it on multiple access points because the issue might as likely be on your router's end.
As for the 3G, that might just be the area where you're at. It happens a lot more if they're doing maintenance on the towers. I have no insight on 3G, unfortunately.

The same behavior occurred on 3 different routers (home, starbucks, and school). Luckily enough, the newest phone seems to be working ok after 3 hard resets, so I've got my fingers crossed that it stays fixed...
