I have rogers High Speed right now, but it giving me problems.

The modem will disconnect at random, re-connect about 30 seconds later, and sometimes disconnect again 10 or seconds later.

This is really starting to **** me and my brother off.
i've called the tech support a few times, they sent a guy out on monday, which he didn't know what the problem was, but he replaced the modem.
but it is still giving me problems.

and its the same price for rogers and primus $44.99 a month CND

TIA
