I had a similar problem with another provider. accept it was more
difficult getting it back up.
After sever service calls, one of the techs showed me a meter
reading. I forget if it was 15 or 25 Db, but he said it should be
0. he put an attenuator on it and i never had another problem at
that location.
I don't know how you could check or attenuate the cable signal
yourself, but if you have an idea it may be worth a try.
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.
