How about your receiver firmware version? I saw in GearLink 9.00.07 was supposed to release on Sep 30 to fix the disconnection issue on receiver. But mine stuck at 9.00.05
I tried Armory crate, there was some hardware updates, but not the one 9.00.07 in GearLink. The disconnection issue still exists after update from Armory Crate. and I was not able to changes settings from Armory Crate, it redirect me to GearLink
