I just got Comcast high-speed cable hooked up here about ten days ago. At first, everything was great: I was even getting speeds faster than advertised. Then after a day or two the speeds came down to what they "should" be based on my package. Now, in the last 48 hours, my connection has decided to go ape. I'm hooked up on a Motorola SB5101 and it just drops me cold in the middle of doing things on the net. One second it's online, and then suddenly the "online" light on the modem turns off and other lights start blinking. It looks like it tries to correct itself but in the end I have to physically unplug the modem and then plug it back in to get it online again. I'm not using a router or anything else: it's just that the modem is kicking out on me. I Googled around and apparently this isn't an uncommon problem. The problem, however, is that nothing I've read so far explains it. Some have problems with this same modem on different cable companies, but then some others who have different modems have the same problem with Comcast. Some suggestions have been made about limiting traffic so as not to "overload" the modem (which is annoying since I pay for high-speed internet for a reason), and then many suggestions have been made about firmware, software, routers, etc etc etc. No one has a straight answer and none of the suggestions I've seen pan out. I've even read bs about or blowing a fan on the cable modem to keep it cool and to not have your cell phone near the cable modem . DOES ANYONE HAVE ANY IDEA PLEASE? I've been messing with this thing all day and reset it probably around 20 times. I would call Comcast for support but I'm about to head out for a night shift of work. (I try to avoid calling support until I've exhausted all self-help options and am ready to sit on hold and talk to someone for a loooong time who will tell me things I've already tried.) Who else has (or had) problems with dropped connections on cable modems? Did you find a solution? I will call Comcast as soon as is possible but if I don't get a straight answer about this from them (or whomever) I'm going to have to switch over to DSL (which never gave me any problems in the past). I'm about ready to throw this damn modem out the window.
