Hello,

I recently switched from DSL to cable. No issues on DSL. Since switching to cable, I haven't been able to connect more than one computer to the wireless access point at one time. I have three computers, one running W7, one on xp, and one on Vista. All three of the computers have been able to connect to the WAP when connecting alone.

I am using a wap54g linksys access point. Setup is internet -- coax -- cable modem -- ethernet -- wireless access point

I suspect that your old DSL modem had built in router capabilities and your new cable modem either does not have router capabilities or has them disabled and is operating as a simple bridge or gateway. In either case, the connecting computer is getting a public IP address assigned to it. Most residential broadband service comes with only one available (and usually dynamic) public IP address per customer.

If possible you, should see if you can configure your modem to operate as a router with Network Address Translation (NAT). If not, you may need to replace your wireless access point with a wireless router.
