Internal Cable modem support (or, recommendations for a good external CM)

[jshamlet at comcast.net]

Hey gang,
I think the problems I have been having lately are due to the Com21 DoxPort 
cable modem. The brand spanking new FreeBSD based router is acting just like 
the old NetGear router (which may be good news - the router may actually be 
OK!).

The symptoms are fairly repeatable. Under duress, the interface will appear to 
go down. On the NetGear, I could recover by rebooting (via command - the 
router itself, and the LAN ports, would work fine). On the FreeBSD router, I 
can ifconfig xl0 down; ifconfig xl0 up - and regain connectivity. I would 
suspect the card, but the same symptoms on two routers? That sounds 
suspiciously like a problem with the CM.

Also, having poked around on google, the concensus is that Com21 modems are a 
load of poop - and I have one of the earliest models (I was an @home customer 
before the big bang)

That said, I'm looking to replace the Com21 modem with a new one. I'd like to 
go with an Internal unit, but I'm not sure (1) whether they are any good or 
not, and (2) if they are supported by FreeBSD 4.8-REL (or 4.9, which I hope 
is coming soon)

Otherwise, can anyone recommend a good DOCSIS 1.1 cable modem (with an RJ45 
port)? I'm on Comcast in Maryland, but I believe any DOCSIS modem should do 
the job.

Thanks,
Seth Henry
