I have read various posts and guides about setting up a router with wifi and a separate AP also with wifi that is connected to the router by LAN cable.
Most of these posts say to ensure that the wifi broadcasting from router and the wifi from the AP are on different channels that do not overlap - often they quote selecting from channel 1, 6 or 11.
But these are the 2.4Ghz channels, does the same advice apply to the 5Ghz channels? If so which channels do not overlap? Or is it that with 5Ghz I just need to ensure they are on different channels but it could be 2 channels next to each other?
