My girlfriend has Rogers Portable Internet in montreal, and it's terrible. the modem has to be near a window at all times, it disconnects a lot or becomes really slow in bad weather, and is usually much slower than videotron cable. about once a month, it goes down completely and rogers can't seem to get it back up for a day or so because their system still registers her mac address as connected and their only solution for this is waiting for the lease to expire.
