@BigBugby I've contacted TP Link support and you have to take off the Smart Connection option to change the wifi channels manually. Hope this helps any pother customers coming across same issue.

Hi Kevin I have already done that as per TP Link instructions but there is no option to change channels in the Advanced Wireless Settings?? Any help greatly appreciated

Hi there - is it possible to manually select the wifi channels for the Archer A7??? There is NO option in the Advanced and Wifi Settings. The auto selected channel for 2.4Ghz is set to channel 10-...
