HTC One M8 after 6.0 update wifi problem

After the update to android 6.0 i started getting troubles turning on wifi. When i click the wifi icon it turn to a darker grey like it's trying to turn on but then it changes back to normal. Also wifi hotspot won't work then... When i restart my device everything works fine. I did not have this issue before the update...

Re: HTC One M8 after 6.0 update wifi problem

Welcome to Android Central! There are quite a few problem threads regarding the Marshmallow update for the M8. Unfortunately, it sounds like wiping the cache partition (which I often suggest as a troubleshooting step) might also cause issues with this update, causing the phone to hang during the wipe. I'm not sure if there are any good solutions yet. I would definitely contact your carrier and/or HTC to alert them to your issue. Hopefully, they'll come out with a patch soon, if indicated.
