Router problem (DHCP)

garu · 15-08-2007, 23:14

On my laptop, I can no longer access the internet through both wired and wireless connections. I get an IP address that starts with 169.254.....

I have pinged the 127....thing and it worked, and also I connected my modem directly to my ethernet card and it could connect, so my NIC is working.

Through the router however, I cannot receive any packets, even though it says that its connected. When I did ipconfig /release and ipconfig /renew, it said that it could not contact my DHCP server. The computer that I am using to type this now is connected to the same router and has the same settings for tcp/ip, and the LAN settings.

I have already tried system restore, and formatting my disk and I'm starting to lose my patience. Please somebody try to assist me.

Also, I can no longer log into my router because it asks for a password and username, none of which I have.

You're obviously using a PC and I know that these are completely different to Macs, but this is what I'd do on a Mac given what you have said.

Uninstall/trash everything to do with the router - preferences and all.
Restart
Try to connect with the etherenet cable to establish that the machine can indeed connect.
Now re-install the router's software and go through the set up wizard
This IP address for the router can usually be found on the bottom of the unit
Set your new WEP password and name the network
Restart all devices in line - the cable modem, the router and the laptop - this is important!!
Theoretically the laptop should now connect!!
