You may have something there. If I look at the internal web page of the cable modem < http://192.168.100.1/signal.html > it tells me Downstream power level 3dBmV Upstream power level 50dBmV When I was last visited by a RoadRunner service tech who worked on my outdoor cabling, he told me that the Upstream power level was too high. He also said that he could not fix that with an attenuator but that it would need an adjustment somewhere in the external cable plant. Nothing happened. Maybe I have to try to find a responsive customer service person. Now that I have given away the secret of the Motorola SB5100 cable modem's internal web page, perhaps a few helpful people could tell me what kind of power levels their cable modems report. carl -- carl lowenstein marine physical lab u.c. san diego [EMAIL PROTECTED] -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
