There is a thing I didn't read in your post. It's where you turn off the cable modem, connect the router then power it up.
Cable Provider: RCN
Cable Modem: Scientific Atlanta, Webstar DCP2100
Router: Linksys WRT54G2 Wireless Router
OS: Windows Vista with latest service packs updated and OS x Leopard
Other: TiVo, Wii
The cable modem does not show a consistent receiving signal, which seems normal because it provides internet access when wire-connected to directly.
Router is brand new and has latest firmware, is set to SSID broadcasting on a WAP-T network. Wireless network can be seen on both computers and the peripherals, but there is no actual internet connection either wired or wirelessly.
I had originally tried to set this up as a WEP network but ran into the same problem... Thinking it was a setup problem, I reset all the equipment and started the process from scratch with the WAP network.
I'm starting the think there is an issue with the wireless router communicating with the cable modem but am unsure how to go about testing this or troubleshooting. Could someone please give me some ideas?
Thank you so much!
