i havent tried bypassing the router, because like i said, its not my computer. I have tried the computer at my house, which the router is set up correctly. For example, what i did was: Took my computer out, and replaced it with his. Connected all my stuff, including ethernet cord. When his computer loaded up, it gave me the limited error. Tried fixing it, and nothing. I put my computer back, and i get a regular connection, with no error.
Thats why i dont think its a router problem, because mine is working properly and its not working. I do notice, when i am looking at the auto detect settings, it doesnt seem to be assigning a DNS address. For example, it will say:
Ip address- 169.254.x.x
Subnet mask- 255.255.255.0
DNS-_________ <---- Nothing listed
As i have stated before, when i give my custom settings (set ip, subnet, dns ect), the error goes away, but all interent related programs dont work (aim, internet explorer). Its odd though because when i "repair" the connection, it goes through fine, with no repair errors. When i try to repair it with the limited problem, it gives me a "cant renew ip" error.
If it helps any, its a Netgear router, Motorola surfboard modem
And like i said, ill be trying all of this when i can get to his house, which is on saturday/sunday.
I think i have answered all the questions, and thanks for all the help so far.
