I recently replaced my linksys router with a dell 2300 wireless. I am still using a wired connection until I get a wireless adapter. After changing to the new router one of my computers will not connect to the internet. Instead of being assigned an IP address by DHCP it uses an automatic private IP address (I think my modem address). I tried to switch back to the other router and it still does this. I tried to manually configure the IP address, but still can't connect to the internet. I could see the computer on the network, could ping IP addresses but not domains.
