Our home fusion network worked great for several years. Recently, however, it started going down daily and then several times pere day. It is getting worse each day. Rebooting the router will not bring it up but rebooting the cantenna does. For this reason I believe the problem is with the antenna. I hate to spend $150 for a service tech if there is something I can do to fix the problem.
If there is a physical problem with the system you will need to contact VZW for warranty support or a local contractor to perform the repairs.
Best thing we can do to help you isolate the problem to a physical issue or not would be to start with a simple reboot of the entire system. IF that doesn't help then try restoring the defaults and running everything in that state. If that doesn't work then search for firmware upgrades and try to update anything you can. Last shot would be to look through the event logs on the router and see if there are any clues pointing to one area or another. Go to VZW or your local service tech with that information.
