Hello! I have a problem with my Horizon box, with the 2.4 ghz connections, I can only connect one device at a time, if I want to connect a second device I have to disconect the first one. I don't have any problem with the 5 ghz band, but I have more than one device which connects only to the 2.4 ghz band. My model is SMT G7400/XEN. Thanks!
