I have the subject cable modem in my setup here at home. Also 2 Airport Extremes, one of which is set up as a WDS remote. System has been in place for almost 18 months with no issues. Last week, the modem started kicking out, at least that's what the front lights were indicating. But the strange thing is that when this happens, connectivity is just fine, no problem whatsoever. A simple reset of the modem and all is well again, until it kicks out again. This usually happens every day or two. You can see the modem here, after this happens: http://web.me.com/tonewheel/Motorola_Surfboard_Modem/Surfboard_Connectivity.html I called the cable company, and they say the signal is clear and strong. They also said this can happen if a wireless router is used. Perhaps, but it has been trouble-free for 18 months. Thoughts? Thanks!
