WiFi troubles - Galaxy S III Q&A, Help & Troubleshooting

Alright, let's see if anyone can make heads or tails of my problem.
I bought a Samsung Galaxy S3 about 3 months ago. From the moment I first booted it, I've had issues with wifi. Ever since, I've searched the internet high and low for solutions to no avail and have finally resorted to making my own thread.
So, on stock rom (and with Wifi power save mode OFF), it detects networks just fine, but cannot connect to them. I disabled the password and any security barrier on my home router, and now it connects sometimes. But even when it does, it will only last about 10 to 15 seconds and then disconnect and won't reconnect anymore.
But then I installed cyanogenmod, which changed things up a bit. It will not detect a network unless I'm 2-3 meters in range of the access point, but it will connect and maintain the connection as long as I'm within 1 meter range. For some reason, I can't access Service Mode in CM in order to turn off WiFi power save mode.
Now I'm unsure what to do next. I wish my phone worked right. It's not much to ask I think. I can't send it back to warranty, because Triangle Away can't download the needed files, not even through mobile data (which works as intended I think but is very slow and very weak).
So what do you think, is it a hardware issue? Could I get a private store to fix it?
Any help is appreciated, thanks-

You have a hardware issue, try replacing the aerial module first then motherboard or a new phone.

So there's no chance to make use of the warranty? How much would a repair cost, more or less

[Q] Momentary wifi disconnects?

Can't decide if this is enough to return the phone over, so I'll ask the question to fellow XDA readers: I just bought an Atrix, and overall I absolutely love it. My only major complaint is that, every other day or so, my phone will randomly disconnect and then reconnect to wifi while I'm using it. This happens both at home and on my college's network. It's never more than a few seconds of lost coverage, but it always seems to happen while I'm actively using data. A few times, it's happened while I was on Market and it caused an app download to stall completely.
So, is this a common thing? Software or hardware? Worth getting a new phone? My local AT&T store was... less than friendly (read: shockingly rude) when I mentioned I might want to swap it out, so is it worth the pain of dealing with these guys again?
Thanks!
A few of us had that problem on release, have you downloaded the update yet? If not definitely try that first.
Here is the original thread: http://goo.gl/hCdN1
Its geared towards 5Ghz networks but still has good info.
What I think helped me the most was the removal of blank spaces from my SSID. Instead of "Wired Pirates Wireless Network", try "WiredPiratesWirelessNetwork". There are a few more good tips in that thread give it a read.
Thanks for the link! My campus wifi has the SSID "MizzouWireless", so I don't think the space is causing the issue. I'm running the latest firmware (rooted as well), and for some reason I'm still getting the issue... weird. Thankfully, it's not super-prevalent, but when it happens, it happens a lot. It also seems to be more related to certain apps than others; TweetDeck will update effortlessly, but Facebook has crashed the wifi twice.
Swapping it out = get a refurb, so I would avoid that option unless your phone is completely unusable.
From time to time I've had the wifi connection crap out too when there's an active download/upload. This is on my home network and it happens most often when I try to upload a video to youtube. I get only 1Mbps up so it can take a while to for an upload to complete.
However, for the most part downloads have been ok. I also assigned a static IP address for my phone to help keep the wifi connection. It still craps out from time to time though.
I had the same behavior with my BB 8900 and my wife's BB 9000, so I chalk it up to normal behavior for a smartphone. Our laptops maintain the wireless connection just fine. I have a work application on my laptop that issues an error message the moment the network connection is lost, so I can easily test this .

Wifi not turning on as well as other problems. Please help!

I don't know if it has been asked before but I've got a problem with the WiFi on my A101IT.
Problems:
Sometimes when I turn it on when it has been off it either goes into boot loop for no apparent reason OR just randomly freezes at the boot screen. When it doesn't act up and I finally get on and my home screen comes up and I look for my active Wifi signal.... it's not there?! When I go to try to manually connect to my Wifi in the Settings it gives me some b.s. "Error" reading! When I try to disconnect and reconnect my Wifi connection on my device it still continues to read "Turning on.... Error." Then, if I feel like messing with it, I'll go through about 5-10 tries of turning my A101IT off and back on to get my Wifi signal on my device to connect as it should.
Other side notes:
I have a Linksys WRTP54G VoIP router that is configured to Wireless G network. Never really had any device connection problems until a few weeks ago.... it just all-of-a-sudden started doing this on its own. I also bought my A101IT off eBay from someone who bought it as New and took very good care of it and only used it like 6 times in 1 month. Beside that, I never uninstalled/deleted any file/.apk I wasn't supposed to. (I say I never uninstalled/deleted anything because I have permanent root access via Chulri's Method for FW 2.3.20).
Any solutions?? Please help!
UPDATE: Archos' [email protected]$$ Customer Support representative said to "upgrade firmware and that should fix the problem." Assumptions, assumptions..... you know what they say?! Anyway, I really don't want to upgrade my FW to 2.3.26 due to known Wifi issues still occurring because as I have found... it seems to be that it is a similar hardware issue like Microsoft's Ring of Death for their XBOX 360 Base, Premium, Elite, AND Slim version gaming systems. I may be wrong but I believe it's a NIC issue where the NIC is not fully soldered on and/or the heat from the A101IT's battery cooks the connection of the NIC on the motherboard of the device to where it can only be turned on at random after about 6 months or more. That's my idea...
try to use Wifi manager to control the Wifi again. https://market.android.com/details?id=org.kman.WifiManager&hl=en
It solved my wifi problem on UrukDroid.
And if u want u can get an older version that has the widget to switch for free.
(Although as it's old it might have bugs that are fixed by now)
= your choice

WiFi Issues

So, I've only had my LGOG for a day and a half and I am having issues connecting with WiFi. At first it worked fine but when I left the coverage area and return a few hours later it would not connect. Tried turning off the WiFi but it kept turning itself back on. I reboot the phone and it works fine as soon as it boots up it connects the WiFi no problem. It is my work WiFi and I had no issues connecting to it from either my iPad nor my HTC One X that will soon find it's way to eBay thanks to this beautiful LGOG. If no one else is having issues, I will call AT&T and have them switch it out. I just wish there was an easy way to back up everything, I mean my home screens and app locations exc. It takes so long to set everything back up the way I find most useful.
WiFi on my device has been excellent.

The Wifi performance of this device is unbelievable. I get the best speeds I have ever seen with any device including PCs. It's either a faulty device or maybe your work has strange security settings?
I had this same problem with my LGOG and my home wireless network. It just would sit and try to connect until I rebooted the phone.
That was on stock though. I have not had any more problems with it after flashing the base rom.
My work has standard WPA settings and it was connected fine yesterday. I left again during lunch and when I came back, same problem and had to reboot the phone. AT&T is sending me another one already and a free case. Can't be too mad about it I guess and at least the phone reboots fast.
Have you tried using the ATT smart wifi app? Fixed the exact same issue for me.

I haven't had any issues connecting to wifi, but I've noticed the status bar icon showing low signal even though it's actually maximum signal.
This Has Happened To Me A Few Times

Twice My O.G. wouldn't connect to wifi networks even though it had connected to them in the past. I tried to turn it off and on and scan for the network that I am in range of and it wont show any networks it just says "not in range" when I am in range. So to remedy the situation I turned the phone off and then on. It has only done this to me twice but it's a real nuisance because both times I needed wifi. My phone is stock.
You're in a minority. This thing's wifi blows most other wifi implementations out of the water.

Perhaps you need to swap out your phone

I wish my wifi would stop re-enabling itself. It's chewing up my home bandwidth.
I have been having this issue as of late. It seems to have developed this habit in the last week or so. At first I thought it was Time Warner trolling me but it started happening at work. Something tells me it has something to do with the stock At&T Rom putting the wi-fi radio to sleep and not being able to bring it back online. Reboot fixes it most of the time but sometimes it takes a couple attempts. I have been hesitant to mod this phone still because I would really like to see CM working well before I flash. Also my instinct tells me another possible culprit could be IPv6 on certain routers. That, however, is far less likely unless someone with a decrapified Rom has experienced this issue as it would be a cross platform issue in this case. Anyone else have any insight? Otherwise it's time to get rid of the Att rom.

Same issue here. This is my second LGOG and have been happy with both except for some minor glitches on both with the keyboard freezing up as well as with the WiFi not re-connecting after leaving the area. A restart normally fixed both problems. My first one bricked after rooting and removing all of the bloatware (the phone checks for certain apps upon booting to keep you from removing stock apps). Tried a fix but I couldn't get a Rom at that point as the phone had been out on the market for under a week. I haven't messed with it since but I may try a new Rom and be able to fix the WiFi and get rid of all the bloatware that way.
Just got this ROM running today. No more WiFi issues at all. Some minor ui bugs I am OK with.

The thread is from the sticky on this forum.

Seems like, as usual, At&T bloat ware is the culprit. I experienced the same on my Aria and Inspire. Hope this helps and good luck.
Also I had the keyboard problem but that went away when I switched to the Android default keyboard. One of the other reasons I decided to root was because rather than freezing, the Android default keyboard started typing then the auto correct broke and stopped displaying the words unless you touched the area you were typing in. It really bugged me when it started doing it right after I factory reset. Weird huh?

LG Optimus G Wi-Fi Receiver Disconnect Issue
Funny...I've had some weird home wi-fi issues on two of these.
To explain, I bought mine in December, stock OS of course, and immediately noticed it turning off my wi-fi every time I tried switching between the two home wi-fi SSIDs I created when I upgraded to DD-WRT. This also occurred outside my house, but stopped shortly after the nearly-immediate Android OS upgrade came over (and forced me to install it, I might also note; I'd read the thing was just more AT&T bloatware, but two or three boots later, apparently I got no choice, and it auto-installed).
The good news was, somehow, this 'update' somehow stopped the thing from turning the wi-fi off when I switched between IDs (my base router has a 5G 2nd network which I wanna use when I'm around it, but DD-WRT won't support, as far as expanding it--thusly, I have another 2.4GHz signal I use and relay out around my yard).
That bad news is, though, that I screwed up the phone with the Root Toolbox (Lite) by merely fiddling with their bootanim settings on that original phone. And I mean bricked it, solid.
I'd never bricked any phone, so this ticked me off. Luckily, I was still within 2 days of my 30-Day Best Buy in-store replacement warranty, so I took it back, they fiddled too, and gave up on it.
Hence, my 2nd phone...which now, even after the system update direct from AT&T, still turns off my wi-fi every time I try switching to that 2nd SSID, so I'm left wondering if it was even the same update; I don't think I did anything else, and can't see it as a settings issue, because it did it right out of the box, and the first one stopped after the only system update before I got a chance to even figure ANY user settings out, much less any network ones.
So, now I'm 'going shopping' for 'some PlayStore app' that will skip this B.S. and automatically connect to the strongest home wi-fi signal (within reason--sometimes they're equally strong), without obnoxiously turning off my wi-fi receiver as I look at it.
This kind of malarky could spoil some phones for some people, but I'll struggle along due to the speedy quad-core in it [sigh...wah!].
I guess I'm a big baby, seeing as how I don't write one iota of code, but my personal haughty view is that any dedicated wi-fi devices should have better wi-fi connection than any Windows OS made...and, so far, this'n doesN'T!
What a dumb thing to let happen in such a potentially awesome phone...[AT&T!!!]
This might work or not but can't hurt to try. Apparently some people in the new snowleopard JB thread was having similar issues and for a few, changing the security from WPA2 to WEP worked. Although mines been good and fine on WPA2 but worth a try.
Using wep in 2013 is beyond retarded.

DUDE! Senior Members here can be a little uppity and rude...even if they're completely correct.
Glad you called out the 'behavior', and not the 'member', though...
but enough of the technicalities...I'm still looking for solutions...beyond blaming AT&T (too easy), or even the strangeness of getting into blaming some weird kind of manufacturing errors (QC at best), I'm left waiting for a substantial OS update (like, oh a better place of decimal, perhaps?), or worse, an app...anyone look at the state (and sheer number) of 'wi-fi' apps? Anybody here can guess, they number in the thousands, and a Play search for 'wi-fi' gets you astronomically different results from 'wifi', even, so I'm not sure I need to be looking at that.
Maybe it's even somehow that, with the first phone, I noticed this, and somehow added my own home network to the AT&T Smart Wi-Fi 'bloatware' that came with the phone (not the worst evil they've ever done, so far, BTW--it does exactly what I imagined should be going on in the background while you're driving around, indexing locales with free Wi-Fi for you to choose to save later...an idea I would call 'Tarzaning', if you get my drift).
I'm gonna try changing two settings in the AT&T 'Smart Wi-Fi' bloatware to 'My Spots' temporarily, at least, to see if it'll latch onto my home stuff more aggressively. I just can't wait to report back my fantastically successful findings here (right after I buy the domain name 'snarkasm.net').
Oh crap...it's already taken.
Is the AT&T smart wifi thing enabled by default? I can't remember. I thought it sounded useful so I played with it a bit but ultimately I didn't like the way it worked so I disabled it.
Still wanted some way to auto-enable/disable wifi. I didn't have anything to go on, but I picked up "Smart WiFi Toggler" which seems to work well. It uses location-based rules (based on cell signals) by default. I also use AutomateIt to turn off mobile data once wifi has been on for 1 minute, and turn on mobile data immediately when wifi disconnects. I have no idea if this saves me any battery life, but I do it anyway.

[Q] Wifi woes

Hey guys I need some help with my Z2, I've had wifi issues on my phone for a while now with it constantly getting low speeds and random disconnects even when showing 2 or 3 bars of signal. I've tried it on multiple routers on multiple providers and the results have been the same, I've tried editing the router settings including changing the channels, the ghz from 2.4 to 5 and changing the security from wpa to wpa2. I never use stamina mode, or minimize battery usage on battery saving feature when using wifi so it's not that. I've tried factory resetting the phone and using the pc companion to reinstall the software version and that made no difference, I've even sent it back to Sony repair twice, the first time they factory reset the device which was pointless as I'd already done that myself and the second time they swapped out the wifi card and it was ok for a few hours but it soon started slowing down again, I spoke to a Sony rep today and he booked it in for repair again but I'm worried they're just going to fob it off again. He did say that one of my apps may be corrupt but again I haven't noticed anything out of the ordinary with them or any unusual behavior with the phone apart from the wifi, not sure if there's a way I can find if any of my apps are corrupt apart from factory resetting the device and not installing any new ones for a couple of days but even that wouldn't pinpoint which one if any were corrupted. I would just send it back to Sony but at this point I'm not sure whether they can actually find out what it is and I don't want them to just keep sending me the same broken phone back. Anyone have any idea what the issue could be or what i should do so I can stop pulling my hair out and actually start enjoying this device? Thanks for any help in advance

Serious Wifi Connectivity Problem (Please help I'm dying)

so i have this problem for about 3 months now,
so I'll explain the problem I am facing,
I'm connected to wifi unless I'm an inch close to the router, so if I go away, the connection will be disconnected, however, in my work, I am connected to an access point which has put a big smile to my face, but apparently when I went back home, I faced the problem again, and I guess I would be connected to that only access point, which is the first time I've seen since i got this problem, all the routers/modems I tried to connect was a failure(saved, secured) since my phone met this access point.
I already tried Factory Reset, Flashing custom modem, *#0011#, deleting data/misc/wifi, changing settings on router and many many more as I've put an hour of fixing this every single day. none of this works. for what I recall, all I did was download an GPS app(I don't remember what it is) and then poof, wifi is doomed.
I have my iPad and my laptop connected and there's no issue with them, only on this phone.
I'm running 4.3 btw,
does anyone know how to fix this problem? my brain hurts a lot and I don't know what to do. please help I'm dying, thank you
