[L830] Wifi quits working?

Yeah, I don't think it's the band. I think it has more to do with multiple bluetooth devices or certain types of bluetooth devices being used by the phone.
 
Yeah my gf still having the problem. I ended up switching to a 1520 and I stopped having the issue. So part of the problem is probably something with the Bluetooth and for sure 830/Denim specific
 
Yeah I think it might be Denim Specific as well. My wife has the 735 and gets the same problem.
