I am facing issues with internet after installing windows 8.1 PRO Build 9600. My internet (on WIFI) stops working all of a sudden though i am able to sucessfully ping sites etc. I use firefox(primarily) and chrome(secondary) both of them dont work. I am able to get things back to normal after i reboot. This is a nagging problem because i have to reboot the machine in middle of things frequently. I tried to update/refresh wifi once. Please help out/any ideas on the fix. would be greatful. I have tried installing WIFI driver etc. I have a hp compaq 420 4gb ram intel core2duo 2.1ghz..
