I am trouble shooting a linksys router that my friend dropped off. He said that he can't get onto the internet but when he plugs his laptop into the cable modem he can get on the internet
I have the same router (linksys WRT54g) so I started testing.
1. First I uploaded the latest firmware to his router. did not help
2. Reset router to factory defaults did not help
3. Matched his router setting to mine.
B. The only difference was on the status tab under router, it is not obtaining a DNS, external IP address, or domain name.
Any ideas or recomendations?
