Router problem (DHCP)
 

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!!
