Does anyone know how to stop the wifi scanner once it connects to a wifi network. I am sure a lot of batter is being wasted to scan for wifi networks. It keeps saying scanning for wifi even after successfully connected to my home network.

If you have sprint... turn off that crap "automatic connection help" bull****. Same thing happened to me till I disabled it.
Hmm..... I have AT&T SGS3. Glad you were able to turn it off.
I saw this as well, but I think it probably only does this when you are looking at the available wireless networks page since that's when you need to see the networks. It probably doesn't when you aren't looking at it. But I guess it's the old argument when a tree falls in the woods and no one is there to hear it, does it make a sound?

If it scans only when I am looking at the wifi settings, then it should be fine. My only concern was that it may be using battery all the time. Thanks.
You should be able to change this in build. Prop

Or if you download Blade Buddy, you can change the wifi.scan.interval from that instead of tinkering with the build.prop.
there is some known wifi issue

So I just picked up a Thunderbolt from a local Verizon corporate store. The sales rep told me NOT to use WiFi on my phone because of an issue all Thunderbolts are having. She said once connected to WiFi, it won't be able to switch back to 3G unless you perform a factory reset. It sounds like a load of crappy to me, but I'd rather play it safe. Can anyone confirm or deny this out there? Thanks in advance!

I think I've read about a few people having that issue, but simply switching airplane mode on and off fixes it, I believe.
Pretty sure that rep didn't know what the hell she was talking about. I think it's a safe bet these and other boards would be blowing up if there was a problem as massive as that affecting ALL Thunderbolts.
And my wifi is fine!
yea mine doesnt want to switch back to 3g but a simple restart does the trick, and some vzw reps are idiots deff no factory reset
I use wifi all the time, no problems here.
I use WiFi at home and 3G when i'm at work, i have no problem switching between the two, the sales rep that you were talking to doesn't know what he was talking about

Same here no problems switching from wifi to 3G or to 4G
I've heard people complain about this, but the solution for now seems to be turning airplane mode on and back off. From what I've seen it's not a super common problem, I've never had an issue.
Yup, no problems here.

Sometimes my wifi stops working even when its been on all day. It shows its connected and I have a strong signal, but when I try to use an app that needs a connection the app wont connect. The only thing that fixes it is turning wifi off and back on again. On top of that I noticed huge drains on my battery when this happens.

same thing happens to me. then if I turn off my Wi-Fi sometimes to try and get a 3g connection it takes like 10-15 tries to get a data connection. And even sometimes when that happens I'll turn my Wi-Fi back on and my Wi-Fi acts buggy, doesn't connect... I'll have to try the airplane mode trick
I have the same problem. Changing the EPST setting as found from an Engadget Post:

Sort of fixed the problem. However, I rooted to Tesla Coil and now cannot use the "##778#" easter egg dialer anymore.
Just tried the Airplane mode and phone rebooted, doh. Again, after starting up WiFi, no 3G coverage.

No problems here. I use wifi 90% of the day. Although, strangly my router now shuts off its wifi signal ever since I bought this phone. I have to go into my router and setup the network again.

My wifi connection is dropping within seconds of connection. The phone switches to 3g, wifi turns back on and connects again for a few seconds, drops then kicks back onto 3g.
Ive had this issue on multiple roms, so I am relating it to something similar to RezRom and CleanRom or to the leak itself.
Anybody have ANY ideas?
Update: seems that after the firmware update, my router and phone did not like each other. I was able to tweak my router quite a bit and it appears that the dropping connection issue is resolved.

It is a wireless N router? I do believe I read that our phones are having issues when on the 5Ghz band.

The phone does not have 5GHz abilities, but regular 2.4Ghz N is supported.

EDIT: Take that back, however it doesn't see any of my 5Ghz access points here at all.
I have a wireless N router at home with no problems. It is on the 2.4ghz band though. I think.

Ditto. My wi-fi is dropping intermittently. If I toggle it off and back on, it starts working again.
What router tweaks did you do or phone tweaks?
My rezound picks up N 5ghz just fine.

I'm having the same problem. However, mine doesn't drop out within seconds, it'll probably be good for a couple hours then I'll notice it's trying to sync with my Exchange server for a while, and will eventually time out and then I lose all internet connectivity until I turn wifi off and back on again. This happens on multiple wifi networks, including wireless-N and non wireless-N.
I do also see that the 3g icon will come and go every few seconds when connected to wifi. Anyone know if this is just a bug with the new ICS leak or is there some kind of fix floating around?

I am unlocked and rooted but I am running the stock ROM and mine does exactly what yours is doing. I don't actually know if this happens outside of my house since I'm generally using 3/4G then.
I have a thread on this in the question section but no answers yet.

This is true. The rezound does seem to have 5ghz capability. However my POS netgear doesnt get the same distance on 5ghz as 2.4ghz.
As far as what I did was actually reset my router and update firmware. This seems to have fixed the issue for now. I only started having this issue with the updated leak and it was happening on all roms and even stock. Reinstalling a ROM would fix it for about 2 to 3 minutes then it was back to switching between both data and wifi.
My phone burned up the battery in a matter of an hour and half as it was constantly going from wifi to 3g.
My phone does the same thing!! I think it happpened when I flashed the new leak zip without re locking vootkoader. In hoping that official ics will fix it

Just curious if anyone found a solid solution to the Wifi problem that we seem to be experiencing with the new leak? I tried the suggestion of disabling auto wifi in the dock mode but that didn't seem to fix it for me. I guess I'm just trying to see if this is widespread, or if it's only affecting certain people in different scenarios. It doesn't seem to be getting as much attention as the overheating/battery life issues that others are reporting.
So far I've tried connecting to multiple networks with different security types (open, wpa, wpa2, wep) all seem to the have the same result of showing that wifi is connected, works for a couple of hours, then will lose wifi connectivity, even though the wifi indicator is showing that it's connected. I've done everything i can think of other than re-flashing the ICS leak. I've also never unlocked my phone, just installed the update per the original instructions on Android Police.
I'm not sure if it is just the connection or something else, but ill try to explain it.
I attend University of South Florida and we have a wireless internet throughout the entire campus. I connect to it using my student login. When on the network, it works great, ill lock my tablet and then come back and it will be disconnected from the network, and to reconnect I have to disable wifi and enable it and reconnect with a like 30% chance of reconnection.
Is this a modem problem or something? I havent heard of anyone around campus having this problem. My mobile data works fine, but Id perfer to save my data. I havent gotten to try any other networks because I live on campus and dont go off much.
When my mobile data is on, I will check periodically and it will be connected to the usf network randomly. Im very confused.
I am using a verizon 4g lte 10.1.

I think I figured it out. I believe it was something with the wifi sleep policy. It was set to turn off wifi at lock and start using mobile data.

I have had the Galaxy S3 for just over a week now. It's rooted, but still running the stock ROM. Honestly, I like it how it is, though I did want backup and recovery options. Waiting for Cyanogenmod's version 10 when it's more stable. ;-)
Anyway, for now the WiFi connection keeps turning ON when I'm just out and around with the phone on 3g (ugh, LTE not lit up yet..). Is it turning on because I'm getting spotty signal? I don't really see it being a battery drain (I'll get a full 24 hours or even 36 with regular usage and WiFi on:good but it's unexpected behavior - and I don't like unexpected behavior.
Any reasons why this is happening? Any fixes for it?
Are you on Verizon? They set it up to keep reminding you to connect to wifi when it finds an available wifi connection. Search through the development section as there are ways to get rid of that.

No, Sprint. Should have specified that, sorry. But I'll poke around in the development section and see.
It was buried in Settings, More Settings, Mobile Networks, Automatic Connections. So simple!
I think that option is so it can connect too 4G as well, unless I totally misunderstood that when I read it

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.
