ASUS X555LA, bought new in January. Used it daily on the Phoenix AZ Public Library Wifi. No issues.
Installed the Windows 10 Anniversary update on friday. Immediately started having wifi problems. It will connect and give internet access for 1-20 minutes, then no more internet. Computer thinks I am still connected to the wifi, but 'no internet connection'. Disconnecting and trying to reconnect gives me 'can't connect to this network'. Rebooting allows connection again, until it fails. Again. Deleted and reinstalled wifi multiple times. Didn't works. Diagnostics say its fine. Others can connect to library internet, as can my smart phone- it's me, not them. Googled for fixes, tried them. Didn't work. Saw recommendation to change DNS server from automatic to 220.127.116.11 and 18.104.22.168.. Worked for an hour. Then didn't. Started ITunes to get podcasts, lost connection. Rebooted, started ITunes again, lost connection again. Rebooted again. Switched to Grover Podcast. Lost connection. Rebooted.
Now I'm here.
