Hi, I've WRT54G v2 with firmware 4.21.1. Everything was working fine for few weeks until one day my internet connection was lost, maybe a power issues. It is very wierd becaouse: 1. my computer gets dhcp and pings the router. 2. the router gets dhcp from the modem and pings the DNS. 3. the computer can't reach the DNS. I've reset the router to it's default settings few times, but nothing helps.. the auto update tool in this site didn't work - it said it can't find the router?! anyone can help? Alon.
