Working Cable Modem - No connection through Router

System Breakdown:

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

Problem:

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!

Already Powercycled...

In reply to: DPC2100?

Hi DCP!

Sorry, I rewrote the original post to try and streamline all the information as best as I could that I accidentally deleted a line mentioning that I had powercycled both the router and the cable modem a few times already. (Even went so far as to disconnect the cable modem from the cable line for 10 minutes to ensure it would have to fully re-establish its connection).

Given that, I'm pretty sure its not a reset issue.

How I fixed it!

In reply to: Working Cable Modem - No connection through Router

I notice a lot of the help forums never put up a post mortum and while this thread didn't help me it may help others.

What I did that finally worked:

1. I used the PC to access the router settings at 192.168.1.1
2. I turned off the routers DCHP functions as the Scientific Atlanta cable modem is actually acting as one - so stop the conflict! Grin
3. Finally, I cloned the PC's MAC address to the router.

It works! Everything works!

As a final note, the TiVo didn't work until I told it to create its own IP address. I've never had to do this before - I've run it on three other networks and always had the DHCP server assign the IP... but it just didn't work this time.

However, all is well again and I am off to fight another battle - setting up the rest of the office. (Gesh - I hate moving)
