I have a WRTP54G Wireless router by Linksys. Now I have DSL which they provided me a 2wire router (SBC) with wireless with a built in modem. How can I connect the Linksys to the 2Wire router so that my Linksys can function for the VoIP? I would need to disable the wireless option on one router and disable the DHCP on the Linksys. Which one should I disable for wireless and is that all I would have to do?
