How far is the affected box away from the router? That shouldn't be happening, but the closer you are to the master box, the less troubles you will have. They eventually installed a signal repeater (like an extra router) and it fixed the problem and improved the other wifi signals as well. If you can get a wired connection to the box, you will be fine. Call them and ask about your options. It sure helped here!!
