This morning I noticed my home wifi wouldn't connect. It's worked up to today. My home computer still works fine and is connected. I restarted my phone and forgot my wifi and set it up again but it won't connect. Any suggestions or is anyone else having issues. Little bugs here and there. This is a big deal to me. Thanks

I had the same issues right after I updated my HTC One to 4.3 not connecting to wifi. I ended up calling HTC tech support and this is what they had me do and it seemed to work.
Go to Settings>Wifi>Advance (top right)>Wifi Frequency band and select 2.4 HGz only.
1. Hold power button and shut down phone.
2. Once the phone is shut down, hold the volume down button then press power button for approx. 3 seconds and let go.
3. You will see a white screen, using the volume buttons for up/down and power to select: scroll to Recovery and press power. The screen should be black.
4. Now press the volume up then power button for approx. 3 seconds and you should see a black screen with blue lettering and a red triangle in the center.
5. Scroll down using the volume down and select Wipe Cache Partition. At the bottom will say Cache wipe complete in yellow.
6. Press power button selecting Reboot System Now. Phone will reboot and should be working. Try to connect to wifi.
Hope this works, if not then call HTC using a different phone to troubleshoot.
