I need something I can revert to when the DSL goes down. It doesn't happen often, but when it does, it can be for a few hours. If we lose power due to a significant storm, it could potentially be down for a few days since there is no back up power on the remote DSLAM. I'd prefer something that can feed a LAN like the DSL does, but I could tolerate something that would feed only one PC either by Bluetooth or USB if not by Ethernet. I wouldn't mind buying a modem for a cell based system, but I can't pay a monthly fee for something I would only rarely use. I'd be looking for something to take out of standby and pay a daily rate only for the days in use.
