I got a USB551 modem for my client the other day I ran some speedtests with it and only got about 640 kbps. It was just hooked up to a XP PC for testing. We are in Queens NY. A place that is suppose to have full coverage for 4g. Why wouldn't I be getting better results with it? They were going to use this as a backup to their existing Time Warner connection. But with speeds this slow they can't.
Any help would be appreciated.
