Have you used a program like Everest v1.51 or SIW "System Information for Windows" to see if the RAM is correct?

Actually from what I can find out your VoIP (Cable telephone) only has a pass through and does not have a router. If I were setting up a network with the equipment you have listed I would remove the wired router and place a Ethernet switch after it and allow it DHCP feature to assign LAN IP addresses. You asked. I just like things clean. If your routers all get set back to the default you will have to re-configure them. As a wireless router would be your best move. You can pick on up for about $30. http://justdeals.stores.yahoo.net/wgt624nar.html

Set the wireless router in "Client Bridged Mode". This will allow it to use the DHCP of the first router to assign LAN IP addresses. It will also use the subnet mask of the first router. Like the second router it will become a switch (wireless).

Have you tried a firmware update? In the Device Version drop down box select your version (2.2). Linksys WRT54G 2.2 Firmware Update Jan. 2007
