Have Comcast internet connected to a wired router. Ran several ethernet cables from this router to another room. In this room took one of the cables and hooked up a wireless router. The wireless router is not hooked into the wan port but one of the other open slots. The wireless router works with the laptop I'm using in that room. The computer in the room with the wired router wont connect to the internet. It works without the wireless connection in the other room. Suggestions? Thank you.
on one of your wired computers go Start then Run in XP - (Windows key plus R in Vista and Windows 7), then type in the following, including all the spaces:- cmd /k ipconfig /all -- then press Enter and from the black form that shows up, take a note of the numeric code beside the word "gateway" -- usually something like 192.168.0.1. Type exit to close the black form.
log into the wireless router and disable DHCP. also the LAN IP needs to match the main routers IP scheme. Change the LAN IP to the IP of the Gateway but ending in 253
