My cable modem is Motorola. The only interruptions to service were when 
the DHCP server died, a couple of times at about 2 AM. The modem thinks 
it is fine, but leases cannot be renewed, and all routes die. Mainly 
though, it has been more reliable than 56k, the main problem is that 
AT&T does not issue repair orders until a certain number of people 
complain, or else it gets on a low priority schedule.
