Have you tried checking the modem for the upstream and downstream signal power levels? Depending on the model, you may be able to enter 192.168.100.1 into your browser to access the cable modem and view these levels. Post back with them and we can see if they're sufficient for the network to operate.
Have you updated the firmware for the routers?
Are any of the computers using Windows Vista? According to this list ( http://winqual.microsoft.com/HCL/ProductLi...d=712&f=86b
) the routers aren't Vista "certified" (but they may still work)
If you're using Vista there are several "tweaks" that may help (although I'm not sure that this is a Vista issue):
1) Disable the IPHelper service in the Services applet (Go to Start and type "services.msc" (without the quotes) and press Enter)
2) Disable IPv6 in the Properties for the connection
3) Disable the DHCP Broadcast Flag with these directions: http://support.microsoft.com/default.aspx/kb/928233
