Hi, Sometimes I encounter with the same problem. I think your problem reason is your modem. If you use a network device with broadcom chipset, your problem reason is that. I have 3 modems (cisco linksys, airties and current docsis3.0 cable modem and all of them include broadcom chipset network devices) and 3 computers (two debians one winXP). Sometimes I can connect to modem from Debians but can not be data transfer between my computer and the modem. I get some dhcp error in syslog. I think there is a problem only between linux+broadcom client and with broadcom chipset modems.
