Defective EDA-2100 on modem line??

Hello,

I live in a house with a ridiculously (though necessarily) complex cable set-up. Long story short, in order to get a strong enough signal for broadband internet, one line in my basement apartment had to have an EDA-2100 amp put on it.
Over the last few days, I've been experiencing problems with the modem staying connected. Sometimes, it'll go out for a second, then kick back in; in other cases, it can take an hour or more. After some very rudimentary troubleshooting, I've determined that the only way to guarantee a return of service is to undo all the coax cables going into and out of the EDA-2100 amp, as well as the one going into the modem. That brings service back, though there's no guarantee for how long.
My suspicion is that there's some sort of problem with the amp, possibly needing replacement. Is there an easier way to deal with this? I have problems getting my landlady to bring Comcast out here--should I just replace the amp myself? Or am I barking up the wrong tree here?
I am also somewhat hesitant to bring out a Comcast tech, since we're running two modems on one account. Technically not against the rules, and has worked for almost a year now, but I don't want to risk being shut down.

Any help will be apprecited.

I didn't find the right solution from the Internet.
