My wife and I both have S3's with Verizon.
Neither of use are rooted/unlocked/flashed. For some reason her phone has a lot of problems reconnecting to our home WiFi. After waking up, it'll see the SSID's of all the networks around us, but it won't attempt to do anything with them.
Only way to get it to reconnect is to cycle wifi or cycle airplane mode.
The wifi settings have been set to "Keep WiFi on during sleep" Only while plugged in on both phones.
I've got the routers set to empty channels (there are 2 routers, one is acting as a range extender, same SSID, different channel), and everything else has no problems.
My phone sometimes does this, say maybe once or twice a week, but hers does it constantly. More like a few times a day for hers.
What can I do?
Did you try and "forget" your network info and reinput the key to connect? Maybe try and remove the network saved info then readd it with a static ip and such since its most likely a dhcp issue on your network?

my wife and I also have GS3's and have the wifi set to turn off when the phone is sleeping. My phone when it wakes up sometimes will not connect to wifi. My phone sees the networks available but wont connect to them. I toggle the wifi off and then back on and then it works fine. It will do this sometimes a few times a day, sometimes it will be fine for a few days. It happens at work and home.
Are you on the latest OTA? I had this problem and it all of a sudden went away after I took an OTA update.

Yes I had wifi problems also...setting a static ip worked for me just set it to a higher number. For example I set mine to 192.168.1.199

Yes, I am on the latest OTA update.
Latest ota updates here also. I just set her phone to static now so ill post up in a few days with how it goes. I also disabled the extender a few days ago but it did not change anything.
I dont know if i explained the problem properly though.
The system doesnt attempt to do anything at all when this happens. It says there is nothing in range. As soon as you cycle the wifi it magically finds the network and connects without problems.
I had the same problem or something similar to yours. Whenever my S3 goes to sleep, meaning whenever I turn my screen off. If the phone sleeps more than 2 mins and I go to use my wifi. The phone shows I am connected to my wifi network but it takes 20-30secs for my phone to respond to my wifi and it will all of sudden my wifi is back on. I tried everything from rebooting my router. I haven't tried the static ip change but my wife's Rezound doesn't have that problem at all. It got so annoying that now I just leave it on 4G all the time at home. I do have the latest update from Verizon. Hopefully someone can figure it out.

The static IP arrangement worked for the wife's phone, and also turning the wifi to never sleep works for me too.
I really don't notice a difference in battery life between having wifi sleep with screen off and staying on all the time, so thats how I left it. Also stops the couple second lag between unlock and reconnecting.
I used to have this problem on my home wireless network. Never could figure it out, so I bought a new router (needed an upgrade anyway) and the problem went away. No idea why the phone had trouble staying connected with my older router (it was a Netgear model). Everything else connected with it fine, but my Galaxy always had problems.

Ya some routers can be a pain. I got a cheap $40 N router that cause more issues then not
Sent from my SCH-I535 using xda app-developers app
So, I tried to leave wifi on at all times per the suggestion in post #9. I did notice shorter battery life (not a huge difference). My wifi connect problems reduced, but did not go away. This happens everywhere: home, work, etc. Some times I will be fine for days, and some times it will act up twice in an hour. Don't know what router is used at work, but I know mine at home is a Belkin N router less than a year old. Never had problems with our old phones, and none of my friends at work or home have this problem.
Really wish there was a solution for this.

Has anyone else had a problem with wifi after the AT&T update? I returned my first Infuse because it would not connect after the update.It would show full connection strength , but say "You have no internet connection. Now I'm afraid to update the new phone.

My wifi connection is better since the update. You may want to check other things like your router, etc. Try the Wifi Analyzer app available in the market to help you troubleshoot.
wifi not connecting unless turn off then back on?
I'm new to this but Im having wifi issues as well. No matter what wifi i go around i have to turn off then back on my wifi for it to connect. Does any body had this issue or know what might be wrong?
Do you have SSID broadcasting enabled? My Infuse wasn't able to connect to a hidden SSID after the update.. Had to broadcast and enable security to get it to work.
Got the phone today. Wifi issues right off the back. Can't even get past 128kb. lol.
Phone is being returned.

Okay I posted a while back about this. For the past 2 weeks my wifi will connect and about 5 mins later won't load anything, but says I'm still connected. I've unplugged my router ( At&T router) and plugged it back in, no difference. I had att replace the router today and still having the same problem. I have it on wpa. I need to fix this, I run everything through my phone and this is really affecting my day to day. Any advice?

If you're still using the stock ROM like I am, I'm finding the WiFi reception on my Infuse to be the worst I've ever experienced on any phone I've ever had. Lets hope the Gingerbread update fixes it.

Download wifi analyzer from the market and look see if there are several wifi networks on the same channel as your wifi. If so, change the channel on your router and see if that helps.
Also, what's the model on your router?
Even I've faced this issue ever since I got the phone but still there's no fix.
The problem is with a particular make of the router. I read online about it and there are more than 2 problems here.
1. If the router is a multiprotocol - bgn router, it might be a problem if the router is running in mixed mode. Our phone supports only b and g. In any case, if u enter the MAC address of ur phone into ur router, it might solve the problem.
2. If the router is not broadcasting the SSID i.e in hidden SSID mode, there might be wifi issues. Change the settings to remove the hidden SSID.
3. There is a PSP mode (Power save polling) mode in the hardware which will put the wifi to sleep if the phone goes to sleep (It is different than the wifi sleep policy) If the phone goes to this mode, some routers wont be able to send packets to the phone and this causes wifi to get disconnected.
If you try to connect to a public wifi, u should be able to connect. I guess the problem is only in ur home. I have the same problem but sadly i cant change any router settings since I stay in a university dorm...
Hope this helps!

Wanted to say I have a Verizon Actionteck router with FIOS and I am having the same issue with my Samsung Infuse 4G, only I am not using WPA I am using WPA2. I have to restart my device and then the device will work. Currently with WPA2 and I hide the SID and have the setting "Connect even when not broadcasting" enabled.
Thoughts ? I still have the 2.2 OS yes rooted.
My phone keeps dropping wifi and then reconnecting on my home WiFi network... I have heard there has been issues and that the network has to be configured the proper way... Does anyone know the exact settings that it should be configured? Thanks for the help!!!
Sent from my SCH-I535 using xda app-developers app
I don't know of a specific configuration which solves all issues and Verizon told me that Samsung was planning a "second" update in October timeframe the addressed WiFi connection issues when I called in July about this.
That said, my WiFi connections have been far more solid since then for no apparent reason, so perhaps there was temporary interference at the time - I did adjust my router to use the (2.4GHz b/g/n) frequency up to 130Mbps for the channel (6) used by my Galaxy S III, instead of the (5GHz a/n) frequency that is configured for up to 300Mbps, but am not sure if that made a difference.

Thanks! Its weird because my wifi at work connects just fine but at home it goes in and out every 30 seconds to a minute...It must be the router configuration...im gonna try and mess with the settings when i get home
It's a problem with your home router or main modem. Verify that the ip on your router and modem match, if not sync them. That's the most common problem. Also, reset your main modem, have your provider ping and update it. This happens to me time to time, mainly with netgear products.
As mentioned above, use the 2x not the 5x band if you have a dual band router.
Also, some cable Internet connections can get fuzzy if they are using old co-ax wires in your house.

You know I was having the same issue. After owning the s3 for 5 days now, after the 3rd day I started to experience wifi issues. I would be connected to my wifi but no Internet connection af all. So I messed with the channels on my Netgear dual band router. I switched channels from 1 back to 6. Still nothing. Finally I reset my main modem(att) and also reset my router back to factory settings and still nothing. My wifi has been working fine with no hicups until I got the s3 and my wife has the rezound with no problems what so ever. Until yesterday, what I did notice was my whole Internet connection went down. Now I don't know if it's att or me. Well, it's back up right now but what I did do was call Verizon and they had me take out the sim card and reboot the phone while they did some things on there end. After they came back from hold I rebooted my phone and since then I have had not 1 wifi drop at all. They told me if I have anymore problems, that I go to the nearest Verizon store and get a new sim card. But I really don't know how that would help out at all since the wifi is built into the phone. Those techs are funny. But ever since that rebooted and removing the sim and also having Verizon do some things on there end. It's been perfect and no drops at all.
Ohh and also I did do the *#0011# wifi sleep mode trick to off. Didn't work for me also. But what was weird when I did that trick my phones screen wouldn't go to sleep. It would stay on until I hit the power button to make it go to sleep.

My note is functioning normally! I dont have any problems with connecting to wifi at home, friends' places and even public wifi at like tim hortons etc.
BUT it doesn't connect well to the wifi at my university... and it definitely isn't the problem with the wifi signal or anything as my phone (galaxy note) connects fine as well as my laptop etc... I am not sure how to solve this problem... let alone figuring out what exactly is wrong...
In order to sign into the school's wifi, one will need to put it an id and password.. its a WPA wireless network.
To be more precise, my note sometimes will be connected to the school wifi fine without any disconnection but very frequently (at least 75% of the time I open up my tablet at school) it will not be able to connect or sometimes disconnect stochastically. I will have to try turning my wifi on and off a few times and if that doesn't solve the problem (which is the case for most of the time) I try restarting my tablet.... most of the time if my tablet decides it doesn't want to connect, nothing seems to work! I will just have to try and connect to the wifi some other time.
Any suggestions?
Thanks!

Your school Wi-Fi just sucks, it's unstable. Or you have on your note an app that uses an restricted protocol. As an example, a router can be set to drop any yahoo related connection. But most likely just an incompatibility between your note and the router.

Could it be a region area cause wifi networks of that size have a lot of different routers all over the place working together and each router can be programed individually to do certain things like drop as the previous post said yahoo related protocol for example so does it work in some areas and not others
I'm having this exact same problem at my school. The wifi will intermittent reconnect, and sometimes won't automatically connect when I enter the building, regardless of the signal strength. It will say "authentication error" sometimes when it doesn't auto connect. Often it will also reprompt for the WPA key even though the saved one is correct.
Wifi works flawlessly at home, work, and friend's houses, but has issues with the school's.

Had similar issues at my school, its not your tablet its the wifi generally the signal strength is bad and that's y i struggles to connects but works sometimes, i realised it was router and signal when even iphones had problems
I made a topic about this a while back. The success of connecting seems to depend on the proximity to the wireless base station and amount of other wifi devices. Even in the worst environments, if I go into settings and disable/enable wifi multiple times it will eventually connect. I get the authentication error fairly often and just ignore it, disabling/enabling until it connects successfully.

Anyone else have issues with the Internet dropping. Signal shows full connection to LTE, but I won't get internet until I toggle airplane mode or reboot. Happens once or twice a day... Do I have a detective unit?
I have the same problem. Mostly at work when I'm on wi-fi I have a weak LTE signal and I have to text I have to toggle airplane mode.
I've been on the phone with AT&T about this situation on two different occasions. Never happens on Wifi for me. They're sending me a new phone.

Yes!!!! I'm having this problem. I had it happen a few times last week and today it was completely bonkers. Its kind of aggravating. I'm considering swapping it out but I'm afraid it'll be the sane thing. So then I wasn't sure if I should wait for a software update.
No matter what, I can never stay away from android for long.
This happens to me on Wi-Fi after being on the phone. The Wi-Fi connection does not work while on calls. Anyone else having this issue?
Hmm my Wi-Fi was working great at my work. I come home and it didn't even see my network as being active/didn't auto connect to it. I've had the phone two days. A reboot fixed the Wi-Fi and it connected back up fine after. I'll have to keep an eye on it.

Ive had the same issue where it shows strong LTE signal but nothing works. Just yesterday it did and I had to toggle airplane mode on and off before it works. Ive had this happen now 2 or 3 times. Not sure Id call it a deal breaker but its annoying for sure.
Yea I feel the same way about it being a deal breaker or not. I don't think exchanging the phone for a new unit will help cause obviously we here are all experiencing it. I love the phone enough to not want a different phone, so I think I'll wait it out for a software update.

Yes, happened to me twice on LTE. Usually it happens in the morning after I unplug it from the charger. Had to turn on airplane mode then off to fix it. Annoying for sure.

Exact same issue here. Started a thread about this in the G3 section (prior to the AT&T G3 section being created) and still haven't received an answer there either.
Like someone else said, I had this happen on my G2 as well. Even remember it occurring once or twice with my Sony Z2. So far, only once on my G3. Toggling airplane mode off and on corrected it. So, not sure it's the phone.
This has happened to every phone I've had since mg iPhone 3g. I don't think its a phone specific thing for that reason. I had the same issue on my S3 and Note 3 as well. Its annoying but I haven't found a way to fix it other than toggling airplane mode.

Just curious, is the internet dropping out completely to where the icon goes away or is it just not loading web pages or stuff like that? I noticed that if that "allow Google apps to scan" thing is checked then it messes up the connection sometimes. Even if you uncheck it, it still may cause problems, so what I do is "forget" the network I'm signed into, turn off WiFi, turn it back on, and reconnect. That usually fixes it.

I had the same thing happen on my s4. I thought it was an AT&T thing
I've had ATT for two and a half years first an iPhone 3GS and then a GS3. Don't remember this happening with them. And even if it did, it wasn't enough for me to go on a forum looking to see if others were having the issue.
are you referring to what I made a thread about? Yes there were times on my S3 the data had issues, tho yea I didn't wind up checking on here. But could that be bc the G3 actually tells you? But then again, the "no connection" thing just started on mine last night.
I have had this happen a few times over the past few days. Was waiting for a phone call, and it looked like I was connected. Had 4 bars,4g icon, and the activity indicators were blinking. But no data or voice was getting in. Needed to reboot to get it back.
FWIW, I didn't have this happen until I removed carrier iq. Since I did that a few days ago, it's happened probably 4 or 5 times. Not necessarily relevant, but it's the only thing I changed before it started happening.
