My apologies, I thought I’d clicked on the X5 model. If a mod would please relocate it?
But, in response to your suggestion: I can’t differentiate between 2.4/5 bands on my network without making network-wide changes, I.e., disable one band or the other. I would assume that the unit connects to the best channel it sees on the network. Thus it wouldn’t, at least in my mind, make any difference if it was 2.4 or 5. Either way, the unit fails to connect to my network immediately as it should. This leads me to believe a probable(?) issue with the WiFi section of the unit.
