1.0 out of 5 stars Dropped signals, couldn't get DHCP address for router, March 2, 2005

This review is from: Cable Modem USB & 10/100Base-T DOCSIS 1.0 (DOCSIS 1.1 Upgradeable) (Personal Computers)

I've had a couple of issues with this modem, specifically dropped connections, and difficulting in getting it to work with a couple of pieces of equipment.

1) Over the year or so that I've used this modem with Cox cable, I came to expect a lost connection every couple of hours or so, requiring me to renew the DHCP lease. I had figured that it was spotty service w/ my provider until a friend in the same neighborhood got cable modem service, and found it to be rock solid. After spending a few minutes on the phone w/ the cable company technician, we determined that signal strength in my area should be fine, and they could find no upstream or downstream issues that should be causing the connection to drop. The other strange effect was that the modem would have to go through 3-4 rounds of negotiation to get sync'd with the cable. The cable companies conclusion was that it was probably my modem.

2) My other issue was in using a router/firewall. I had one left over from my previous residence (where I rented a toshiba cable modem). Despite numerous tries, I could never get it working with this modem and Cox. I eventually gave up and ran zonealarm instead. I've also never been able to get another machine to work with this modem, even with direct connection.

After figuring out that the dropped connections were probably coming from the cable modem, I got a linksys cable modem. It's been rock solid since changing out, not a single dropped connection. It is also more than happy to deal with my firewall/NAT box. I may have had a bum modem, but wasn't able to get through to Zoom tech support to figure that out (spending all day on hold isn't worth my time, when a new linksys was just $70).
