Why does my wifi only work in Airplane Mode?

Wifi Only Works in Airplane Mode

I can only effectively use either 4G or Wifi in airplane. I have a HTC One M8. I have seen a couple other posts related to this but no real answer as far as I can tell.

Re: Wifi Only Works in Airplane Mode

I've never encountered this problem with any of my devices.
I'll ask other members with HTC phones.

Have you done any changes to the network settings?
