i am having trouble connecting to 2ghz network, i have tried two different phones, and it connects then drops out all the time. The trouble with this is my wife's phone can only connect via 2ghz. Forgot to mention i have hub 3.0
Go into the Hub settings and in "smart wifi" - disable the channel optimisation feature. You can also rename the ssid's of the 2 networks so they are clearly separated so that you can "force" each of your devices to connect to the one of your choice. Also try a wifi analyser App to identify which of the three non overlapping channels (1,6,11) are least in use around you - and select that one to use
