2. when installing the ex7700 using the installation assistant, uncheck the "extend 2.4ghz network" button. You'll still be able to use the 2.4ghz but it won't act as a failover for the main 5ghz backhaul. 2.4ghz is slow and sensitive to interference. If its acting as failover and for some reason the 5ghz drops, it tends to cause issues. I wish it was unchecked by default.
