Reading through other posts with similar setup/connection issues. (4) times on separate days dealing with Verizon tech support to so far no avail. Just switched to Verizon from another major carrier and need this device to work for my basement home office. I have the unit setup properly, went through all the major troubleshooting exercises with reboot, resets, etc etc. Unit can see satellites, connects to servers then blips out to error 8C every time. Cannot connect phones. As far as I can tell, my router can see the unit and I cannot see anything there with the security/firewall that would prevent the unit from working...however I'm not 100% sure of this, and it seems there is no one on Verizon''s end that can walk me through this so far. I must say after multiple tech people transferring to each other on any given day, they are very nice and I believe are trying to help, but this was not an issue with my prior carrier where I used their extender on a regular basis. Although this issue is becoming a game changer and I may need to switch back to my prior carrier witch will be a nightmare in itself, I did not think it would not work based on my prior experience with my old carrier. Many reasons why I switched to Verizon but this is a killer. HELP!!!
