The only issue I've had with it so far is I can't access the configuration wirelessly from my laptop. Wireshark says that the FIN packet that comes in to end the HTTP session has a bad checksum... repeatedly. So who knows what that's about.

It seems to be happier than my server when attached to the modem. I'm still not sure exactly what the problem is, but my best guess is that it is some bizarre incompatibility between my network cards (both the same model) and the cable modem. Nothing else makes a whole lot of sense given the information I have.

Let us know how this plays out and what the eventual solution is. *holds breath* I guess Comcast does care. Let us know how this plays out and what the eventual solution is. *holds breath*

Every box on my network works fine when plugged directly into the modem (if I reboot the modem first) but if any traffic is routed through any of those boxes, I start getting RX errors from the modem. Since this same configuration has worked with several other ISPs, I am reluctant to conclude that there is a hardware problem behind the modem; the most likely place seems to be on the modem itself or upstream. If you have any diagnostic direction I would appreciate it. I am running Debian Lenny on the box doing the routing. If you would like to continue this via email let me know and I will send you a quick message. I am unsure how much more directly I could be connected to the modem.

It needs to pull info from our network. Once you can connect directly, then you may be able to introduce more hardware into the picture. First you would need to connect directly to the modem.
