[AC Question]

I bought a HTC One E9 last week.
When I connected to my home Wi-Fi, it disconnected and disappeared from my list of available networks.
If I go to saved networks, it shows it is "out of range". When I forgot the network to try again, I can't find it. Scan, refresh, it's not there.
I tried a few things I saw on other forums:
-rename Wi-Fi direct and Bluetooth device names
-restart
-tried other Wi-Fi networks (exact same at work)
-update (it did need to update, but didn't fix it. Now on 5.0.2)
-restart router
-connect with different device. Tried with 2 Samsung phones, another HTC, an iPod and 2 computers
-disconnect everything from router, only connect the problem phone

None of these worked.

I hope someone can help, this phone is useless now as I can only use it while traveling to and from work.
