Re: PC loses connection ever 20 minutes?
check the router, update firmware, reboot router, disable dynamic DNS, stop using DHCP and switch to static IP, look up if your ISP has a different DNS and switch to it. oh and update drivers, if for example you have asrock board don't look for drivers from asrock, look for realek drivers for LAN (if that boards has realtek LAN) if wifi, for example Dlink, don't look for Dlink driver, figure out what chipset that Wifi adapter uses and look for driver from the original manufacture for example Atheros, ralink etc...)
if router has QOS disable it
do all that and report back.
