does that unit have a wall wart? if so, and its 12 volts out, try
interfacing a small 12v battery.
if the problem goes away, you have a bad wall wart. I had a switch here
that would do that
all the time. I plugged into a 12v battery and the problems went away
(so I have setup all
my switches, and the cablemodem, to live on a single 12v gell cell with
a wall wart to keep
the battery up to charge).

bad lines, have qwest come out and do a complete assessment (don't take
no for an answer, and ask
a lot of questions).

if thats a biz account, they shouldn't be changing your IP every 15
minutes. its beginning to sound like
qwest fubared the account and are placing all the heartache on you (the
customer). thats an old story
that qwest lives up to many a time.

its supposed to. she needs to call the biz office and start up the chain
of command. eventually she'll reach
someone in authroity who is authorized to say "yes" and get something
done. she might also consider cox
biz services. they tend to be reliable and stable (according to DSLreports).
