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.

I only have one router. But I will try changing channels as maybe there's a lot of congestion on the channel I'm using.

I've read about that on here but I don't think my router has that option.
I'll go into the config and see if it does.
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!

Have any of you tried this ^ ? Mine is set up like that, and no issues at all. I did have those issues on my Captivate until I did above.
I'm having a rash of the issue tonight--dropping wifi and now says unable to connect due to poor reception (I'm sitting beside my router)...

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.

Interesting. Given that I don't seem to be having any issues, it seems it is not a problem for everyone.
Had the same problem. Net gear router wrnd3400. Wifi kept dropping so then I connected to Verizon router and no problems. Seems to be a problem with some after market routers.

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

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.

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...
So after the 3.16 update, I noticed my phone was not picking up 4G. After pulling my hair out to figure out why, I traced the problem to the Sprint Connection Optimizer being disabled. Turn it on, 4G toggles on with it, turn it off, 4G toggles off with it. The previous version of the Sprint Connection Optimizer did not do this. To confirm my suspicions I reset the phone to stock and observed the same behavior.
This is quite the pain in the ass as I don't want my phone connecting to WiFi networks that I marked "remember". In addition, I don't need my phone connecting to WiFi at work (which I use for work purposes under special circumstance).
My short term solution is to forget WiFi networks but this is rather tedious. With the Sprint Connection Optimizer toggled off, I am essentially locked out of 4G. I pay for Sprint's service and I insistent on using as much of their/my bandwidth as I chose.
Can anybody else confirm what is happening. My area has relatively strong 4G coverage, to the point where seeing 3G would be a rare occurrence. I need to make sure this isn't a problem on just my device before I roam my way out of my contract.

Why would you not want to connect to WiFi networks that you mark remember?....jw
If you have the option of your local WiFi versus 4G most times I'd expect someone to want to go with the WiFi... Only time you'd want to not is in places where 4G was better connection, which in those cases I wouldn't want to mark said WiFi networks as remember...
Ill try to mess with it here see how it effects my stuff as were rolling 4G a lot now...

In most cases work wifi won't let you watch porn at work man. Total pain in the a$$. We should be able to toggle our own connections. I will say wifi is better on battery and generally faster. However there's potential risk on wifi that someone could access your device. Extremely unlikely but a possibility none the less.
In my area we don't have lte yet and the other day after installing MeanBean I saw 4G pop up in signal bar then went away then came back. Haven't seen it since. I was so excited but I shouldn't get my hopes up. Sprints been saying 4G for a long time and still nothing. Only reason I stay is unlimited data and I live the HTC evo line.
You have a better chance of winning the lottery 5 times than someone accessing/ hacking your phone over wifi without you knowing about it.
Also there are great wifi apps that tells you who is on the network your on at all times.

I have found that Comcast seems to throttle youtube traffic at certain times of the day, and I have a specific spot in my house where my wifi signal just completely drops (but still claims to be "connected.") I'm obviously going to want my phone to remember my home wifi connection, but I don't necessarily want to always be using it at home.
My situation may not be incredibly common, but it's a valid scenario where you may not necessarily want connection optimizer to run the show.

The optimizer isn't your issue there though, as the mere fact of having the network remembered in the phone will cause it to connect to it whenever within range.... Its the fact you have a remembered WiFi network saved and you want to override that in a specific location when still in range of the WiFi... In that case the only solution is to toggle it off when you don't want to use it at that specific location in your house...
Optimizers doesn't just force you to connect to your local network that's remembered as the WiFi being on will do that itself already...

You can try disabling Sprint Connection Optimizer and try purchasing Juice Defender Ultimate. If you use its location service, it will only turn on wifi in places that you turn on the wifi antenna and remember them. And if it turns it on, you just manually turn it off until its trained.
So I am on t-mobile, and I also have one of the routers provided to me by t-mobile (I believe it's an Asus) , and I have noticed recently that my wifi calling has been sucking big time. It cuts in and out and says I need to connect to a wifi network, when I am connected. It's like it doesn't notice that there is a wifi connection. Anyone have suggestions as to what might help?

WiFi calling on Android is hit and miss. I wish it was as stable as Blackberry UMA calling.
I tried the old turn it on and off again on the modem and router and it seems to have helped quite a bit.
Unfortunately, I have this issue for a quite while. Funny thing wifi calling works smoothly on pixel or essential phone!
How old is the router?
The router's WiFi radio maybe showing its age by being intermittent with its throughput's strength and/or signal's strength.
Try with newer router or access point. If there is a coffee shop with very good throughput strength (this is most important) you can do a test with that hotspot.
