My Wi-Fi won't connect to any router, how do I fix this?

[BClenney]

Since the Lollipop upgrade my G3 has not been the same. First I noticed that every time I got on facebook it wouldn't update unless I turned off the WIFI. Second issue I have noticed is that my phone will not connect to WIFI at my office. It connects everywhere else.

I have reset the router at my office, That didn't work.

There are other devices on the same router that are working fine.

I resorted to Factory reset on my G3 and it still doesn't work.

Please help, I have almost used up all my data because of this Lillipop update.
