Rain Interrupted Network

I have been experiencing interrupted connection for months now. I have called in to get a resolution with no success. I was advised that my modem needs to registered to the nearest tower, which was done, but yielded no results. The modem keeps disconnecting and restarting every 10 minutes or so. This makes working from home a hurdle (which is my primary place of work). My payments are never interrupted, I don't understand why your service is. It was ok for the first 4 to 5 months or so and then suddenly started disconnecting. I need this resolved ASAP or advise if that is not possible so I can seek service from another provider
