chuck, I have same issues and what I have been doing is cutting coaxial 1 inch back @ connector that goes into modem and the silver wires need to get pulled back (away from modem), make sure you peel back silver insulation also, and dont let any silver tiny wires get exposed outside of connector. This ongoing issue I have hasnt been corrected by my provider (cablevision). They have no clue. They really suck balls. But anyway, try to carefully put connector back on properly. I might have a drop off of electricity, which might crash it, but I also notice that internet explorer is always trying to send report and thats when I crash.

P.S.: When Internet Explorer reports it cannot open a web page (connection has been lost) I check SB5100 and proper lights are on as though everything is fine.

About two weeks ago, my four year old Motorola SB5100 cable modem started losing connection (required reboot) more frequently. Now, if I turn the computer off (wireless router remains on) I NEVER have an internet connection when I reboot the computer, and several times I have lost connectivity during a session. Rebooting (unplug SB5100 power, wait 10 sec., plug power in again) always restores the internet connection. In the past, need to reboot was infrequent. Cable connection is shared with TV (splitter) and TV signal is fine. Any thoughts, or should I just trash the thing and buy a new cable modem? Any recommendations on brand or model?

I am using a Motorla SB5100 modem with a splitter (TV & internet) to connect to Comcast. Using Windows XP. I keep losing connection. How can I tell if it is the cable or my modem? TV on the splitter is fine. Thanks for any help.

For you Hans Malik, maybe it means you to have a router in order to conect more than 1 pc with the modem, i try as well but everyone told me that it can only hold 1 IP so i had to buy a router for more computers in a network, i assume you have to buy one.

Hi, I have a question about this SB5100. Can I connect 2 computer to internet at the same time using both of the connection (USB & ethernet)? I tried before but only 1 computer that can connect to the internet. The manual said that I can do it, does it need any other settings?

Hello, i have an issue with this model, it seems that when i turn on the modem this loads the lights normaly, but after 3 flashes of the ‘PC\ACTIVITY’ light, only the Power light is on and the RECIVE and SEND lights start flashing both at same time, i dont recive any kind of signal from the router, i had it off for 4 days thinking may be overheating, do you know a solution or any kind of help that may solve my issue?

Im a Canadian user whose ISP issues these modems out with the service. I went ahead and bought a modem off ebay so I wouldnt have to keep renting it from my ISP but the American made modem won’t work on my PC with my ISP. Any ideas? Is it possible there is a lock of some type that prevents this modem from being used outside of the USA?

evelyn what you should do is unplug the modem from the wall wait 30 seconds then plug it back in. that should help with your problem and if it does call you local internet provider.
