Latest Firmware V2.5.0.38

This may or may not help, and may or may not be pure coincidence - but reading the solutions (factory reset) presented made me irritated enough to post it as a suggestion -- in case it helps.

I decided to try to poke and bang it a little, so to speak, to see if anything came loose - I turned on "Access control" ( [Admin_Base_URL]/adv_index.htm ) - just turned it on, nothing else. After a few minutes, it started showing everything, Could be a coincidence - no idea.

One other thing: despite the web interface showing no satellites attached, I used a wireless card in "monitor mode" to verify that the routers were in fact connected and talking. (Aircrack-NG, Kismet, Bettercap etc - tools we don't talk about in polite conversation, but they help here!)

Best of luck!
