At the end of last month I was sitting in my house and my phone said "roaming" and asked me to choose the state I was in. I was in my home so obviously I wasn't out of state. Didn't think anything of it..
Then about a week later, I begin to have troubles connecting to my home Wi-Fi. Nothing had changed with the Wi-Fi everyone else had no issues. It said it was "saved, secured" but would constantly search and try to reconnect. Sometimes, I can connect, however it is very slow, messages and such "fail" and often gives me the loading symbols within all my apps.
-I tried a factory reset just for trial and error.. This did not fix the wifi issue.
-I cleared the cache for trial and error.. This did not fix the wifi issue.
-I tried dialing *#0011# > Wi-Fi> toggle on button.. This did not fix the wifi issue.
-I even tried installing WiFix and a WiFi analyzer and these did not fix the wifi issue.
This issue unfortunately happens at all 3 permanent home Wi-Fi locations I use. I never try to connect to a public Wi-Fi such as Mcdonald's so I wouldn't know if the issue still remains.
-I know for a fact all passwords are correct. Out of the blue, this issue just popped up.
-I tried forgetting all 3 Wi-Fi locations and re-entering passwords.. Still did not fix issue.
-I have done research on the computer, searching for answers and suggestions.. All which I have tried and nothing resolved this issue.
I called into T-Mobile, they said they have had some complaints about such (please note this is before 4.3 update!) and that they would send me a free micro sim card and see if this resolves my Wi-Fi issues because they were updated. I tried this, and it did not work.
I have called in today again to T-Mobile after receiving the 4.3 update, to ask for any suggestions to what my problem is. I was praying this update would fix the issue.. But it didn't and I have run out of options. My warranty is up.. I absolutely love my s3, I treat it like my baby.. No scratches, no drops, NOTHING bad has happened to it.. I have run out of ideas and patience..
The rep I talked to had tried searching but couldn't do much because there wasn't an error code. I will most certainly keep my eyes peeled if anything new pops up and then place another call into T-Mobile.
I am on the prepaid plan which is $50/month, first 500MB at 4G speed, then to my knowledge when that runs out it goes to 2G. I turned off my data because I burned through it because I couldn't connect properly to Wi-Fi. I don't feel like I should have to waste all my precious 4G while I am in my home and should be able to connect to Wi-Fi.
