I have done more fooling around with the boosters. If they are both plugged into the modem they transmit a signal and the light remains blue. Even after resetting and running the app install procedure, everything says great...until you unhook the 2nd booster from the modem. I have the first booster connected to the modem as directed and it appears to work fine, even though in the app it says it's offline and there is a connection problem. If I go into the modem settings for boosters I can actually see the booster and my laptop downstairs connects to it, and it appears to be working despite saying offline. I need to get the 2nd booster to work, any ideas?
