One of these has been working fine for years but now is experiencing a strange issue. It seems to have stopped being able to repeat both satellite signals because the MyFi receiver diagnostics display only shows SAT1 which fades in and out and nothing for SAT2. But only for about half of the channels - the other half are fine with solid reception on all channels. And all channels are ok without the repeater connecting home antenna direct in the same window. I"m trying to figure out if the repeater has gone bad or if some change in the satellite configuration is affecting it.
