Wi-Fi Connectivity Issues? - T-Mobile, Samsung Galaxy SIII

When i First got this phone It was working perfect, that was about 2 weeks ago. But now it wi-fi isn't working. It is stock and unrooted. The only time it will connect is if i turn off Wi-Fi on my phone then turn it back on. But then it will only stay connected for one minute before loosing it. And if it does stay connected it only shows one bar of signal strength even though I'm next to the router. Anyone else having this issue? I'm about to just factory reset my phone to see if it will fix this.

There have been quite a few reports of this issue, and the carriers should all have it as a documented bug so you should have no problems with an exchange. Weak wifi & wifi turning itself on have been a problem to many gs3 owners. I recommend calling your carrier & asking for a replacement.

[Q] Anyone having network issues, radio problems?

I am on my second International HTC one X and both devices would lose the carrier signal quit often... I would either go to airplane mode, or turn the network off and on and it would grab it again. Sometimes it would be good for the day and other times, I would have to do it a few times....
I wanted to think it was my carrier having issues (MTS in Winnipeg MB Canada)... however, this has never happened on my many other devices. Now I wake up today and turn on the mobile data, after awhile... it does not connect, under settings it says disconnected because service is unavailable. I tried reboots, restart, airplane mode, checking apn settings.... on my last reboot, it says No signal/emergency calls only.
So now I am fearing a hardware issue (but I find it odd it happens on both my one xs).
I love this device and aside from this potentially huge issue.... I have no complaints, so I will ask here and see if you guys have any solid input.. before I contact htc!
I also popped my sim in and out, as of right now...
Thx in advance.
**update: it almost seems like putting wifi on, knocks out my carrier signal.... after an hour of doing the above things, I turned off wifi, went to airplane mode and now my signal and data is there (it makes no sense) and it is quite a hassle
The weirder part is, it seems to only be in the morning.... once I am up and running, I do not seem to have many issues through out the day, but If I put wifi on long enough... It goes to no signal/eventually....
If I do not put on wifi, it either does not drop.... or I am not noticing.
I've just begun having network problems but I'm not sure it's related to your situation. I'm in Australia on the Optus network.
It happened suddenly yesterday. Service completely cuts out for extended periods. It will occasionally come back on for a short while (long enough to download all my sms) but will then cut out again. When the signal does briefly come back in, the signal strength is decent: it's an all-or-nothing proposition.
Did you manage to resolve your situation? Would be interested to know what resolved it for you.
I've had this phone since early April when it was released here and the is the first issue I've had with it. I haven't done anything new to my phone in the past week so I'm finding this strange. I'm running Leedroid 4.0.0 but I've had that installed for weeks without issue. I'm worried it could be a hardware issue.
I'm going to try reflashing it tonight to see if it's a software issue.

No WiFi on startup

With ICS when I first turn on my tablet, the WiFi often does not connect, even when the signal is strong. WiFi is on, but it does not connect until I turn WiFi off and then back on or manually select my home or office network. Once in a while this happens I turn the tablet back on after it has gone to sleep.
I tried restoring to factory defaults and it fixed the problem for a few weeks. But it has come back again. Has anyone seen this problem and found a solution?
I am using the OTA version of ICS.
I have also had this problem on occasion, but it seems to be happening less and less which is strange. I haven't gone to the effort of resetting my tablet.
There are many little quirks in ICS that I think will need ironing out with an update. Whether Acer think it worth their while is another matter.
I am on stock ICS - Rooted.
I know its not a fix, but normally I just toggle airplane mode from the system bar. Seems to be the fastest way to get it going. It happens on about 25% of cold boots to me.
Been happening to me every reboot since ics. Another incomplete release.

Network not auto reconnecting?

I drive to work each morning through a tunnel that goes under a river and this usually causes my phone to lose connection. The problem is it doesn't seem to try and reconnect at all, until I toggle airplane mode. This is quite frustrating and I can see this being a major issue if I'm ever using my phone for navigation and lose signal.
Does anyone have any idea why the phone wouldn't be reconnecting on it's own? This never happened once with my nexus one.

[Q] Wife issues just recently started on SM-P600

So I just purchased the tablet brand new about 2 weeks ago. Love it for the most part!
Over the past couple of days though, the wifi has really started to act up, and it's passing me off.. About every half hour or so, sometimes longer, sometimes shorter, the wifi will just stop working for a while. The bars will still be there, as will the little "download" and "upload" arrows lighting up as though data is still being sent and received. However, the wifi just isn't working. Pages won't load, speed test . net app won't work, nothing requiring wifi.
I usually have to go into wifi settings to disconnect and reconnect for it to start working again.
I haven't done anything different to my wifi router, and my other wifi connected devices don't seem to be having any trouble staying properly connected, so it doesn't seem like it'd be an interference issue.
Can anyone provide me with some help?

WiFi Hotspot Turning Off Automatically

I run stock rom, all updated and since the last update a few days ago (droid 7.0 build BDB90W) when I turn on wifi hot spot it turns ifself off again immediately. I've rebooted, double checked settings..
I'm out of ideas !!
I found the problem, basically the phone just decides to revert back to to WiFi when in range of my home router. Smart I guess but too smart as I wanted to hot spot a device off my phone on purpose....
So move out of Wifi range and problem goes away!
