@Sunshine I would have thought the Smart connect feature would do this automaticaly otherwise what is the point of it. Sunshine wrote @Boom2 Hi, You can disable Smart Connect and test the speeds...

I found that disabling the Smart button allowing an option to switch between 2.4 and 5 ghz and setting to just 5 ghz inproved WIFI speed from 1-2 to aroud 20 mbps.
