I have a virgin broadband moden connected to a switcher box which has the ability to have 5 ip addresses running at one time, i have 3 connected to the LAN with no issues but i have just tried to link another computer and its not allowing me to join my LAN. It comes up with Limited or no connectivity. It will not renew the IP address. Any suggestions guys. I use windows XP. I could really do with some guidance. Thanks in advance.
