Since Monday my Deco X20 wifi will not pass 2.4ghz traffic. I can see various devices connected at 2.4ghz in the app, but there is zero traffic up or down and no new 2.4ghz device can join. I tried creating an open guest network (no password) with only the 2.4ghz band, and that shows up as an available network, but again, nothing can join it, including my iPhone. If I change the settings to allow 2.4 and 5, then I can join the guest network.

I deleted the entire network and set it all up again from scratch. The setup went fine, but the problem persists. It's like the 2.4ghz radio is dead or at least not working properly. Does resetting each node using the reset button on the bottom of the device do anything that just deleting the network and starting over does not do?
