[Q] Need wifi help AT&T S3
Ok, so I've had wifi issues for awhile with this thing, but apparently the 4.3 update sent it over the edge. (I just updated it last week, since I was out of the country when the update issued).
The issue is, I cannot connect to any wifi, other than my home. Before the update, I could connect to non-home wifi only through various router setting changes, that required admin access to the router. After the update, no matter what I've tried with regards to routers, my home router is the only one I can connect to, and the signal strength is pretty bad on my phone, while it shows very strongly for any other device.
I've tried all the suggestions in just about every thread I could find. I've done several factory resets, I've tried the *#0011# thing. I've tried using static IP addresses. But the phone will do one of two things. After I click connect, after selecting a network, it will say Saved. Or it will try to connect and then go back to Saved, or eventually give the Authentication error.
I'm not 100% familiar with how android is setup, but is there a specific file that I could try to install that might affect this? (Like a driver)
Would replacing the antenna be helpful, or maybe the chip on the mb? Or are those options too extreme?
Any ideas are appreciated.
