wifi problem after lollipop update

[steve0mac]

Is anyone else having problems with their wifi connection after updating to lollipop. Mine was working fine before update. Was getting around 35mbps download on ookla speed test when connected to my home fibre broadband before update but now not even hitting 1mbps after update. Keeps buffering when watching vids. Checked home broadband speed on pc and getting 34mbps so its not my Internet causing problem. Would appreciate any ideas. Thanks.Using xperia z3 D6603.

Do you have any antivirus, battery apps?

do you have auto backup photos/videos? or auto update apps enable?

[steve0mac]

I've got avg antivirus that came with phone and i think photo backup is on.

[steve0mac]

Auto update for apps is also on

[steve0mac]

Can't access avg cos I'm still in safe mode

This is what I'll do, repair the phone with PCC 

PC Companion (PCC)

Bridge (for Mac)
