I have 2 desk top computers hooked up to one internet source and they are hooked up to a box which my old linksys router was hooked to. I now have a lynksys wireless router G. i unplugged the internet wire from the old router and plugged it in to the new wireless router. I am trying to get a separate laptop to be wireless for the internet. The system says the internet cable is not hooked up. I don't know where else to put it. I've tried unplugging everything but doesn't seem to help. Any suggestions.

You have connected the LAN cable from the modem into the correct Internet port on the router.
This error message you got could mean you have a faulty cable. To test the cable, connect the cable from the modem to your computer's LAN port to see if it connects to the Internet. If not, the cable is faulty and needs to be replaced.

Are you trying to set up the router.
You can do it manually without the CD.
Make sure that your computer is able to go online
through the modem.
If your computer is able to go online through the
modem
Then you need to connect the computer to the
router and the modem to the router.
open the set up page of the router and change the
settings of the router according to the ISP.
