Galaxy Ace 2 wifi disconnect??

hi to all....I have the galaxy ace 2......recently I have been having problems with wifi......for no reason it will disconnect...when you try to reconnect phone reboots.... sometimes wifi says on but isn't???....phone will freeze during updates/dld's......after calling rogers I was told to factory default ...did this multiple times and everything seemed to be ok......but a few days later im back to square 1......I must admit I was using my phone without antivirus and thought I had one.....but when it was working I dl'd avast...and all seems fine..........rogers is saying I must repair or buy brand new at costs greater than what I paid for the phone....so im hoping you guys have an answer .....

Have you tried backing up and restoring everything to default? Sometimes these phones get flaky when they get too much stuff loaded on them.

thnx..I did not back up anything in case of virus but I did factory default reset a few times until I got it working again...put avast on....everything good for almost a week and now acting up again...right now wifi says on in drop down menu and in settings screen...all says good ...but wifi not working????

I recommend you see what your wifi is doing with a wifi diagnostic app, like https://play.google.com/store/apps/d....wifi.analyzer

Have you tried connecting to different networks?

It's possible that something is misconfigured or damaged internally. With one of my older phones, the wifi would only work if I pressed hard on the back case. However, this was a very specific issue with the phone.
