I have a Samsung galaxy s3 with telus (model #: SGH-1747M). I just received the 4.3 update for my phone. It was fine for a day or two and then I started getting a 'internet connection unstable' notification while I was connected to wifi. The wifi is fine and the phone connects to it and shows that it is a strong signal but will not connect to the network with it on wifi. Also my network cuts in and out continuously and is moving really slow.
I read up on this subject and it seems a lot of people have come across this same problem. One thing that seemed to help most people was clearing the cache in recover. I did this and it did nothing, as well I did a factory reset. None of this has worked or helped.
Is there a solution? If not, what are my options? downgrading back to 4.2.2 or a mod?
