My FIOS TV guide on both setop boxes (One digital, one standard) constantly displays this error. I have logged onto online as well as called verizon tech support and did the usual reboot of router, TV and boxes. Also disconnected and reseated the coax to all devices and switched tv's to boxes . All the fixes worked for one day then the problem resurfaces the next. I have had it and ready to dump the service. To me this is a hardware problem or maybe a firmware upgrade on the router. This has been ongoing for months.
Please help!
