It seems that everything involving wifi settings like turning on WPS,  changing wireless mode from Easymesh to Onemesh using the app, or even turning off wifi using the wifi schedule will result in this issue.  When this happened, the 5ghz channel would get stuck in 100mbps mode that even hard rebooting or turning off the router wouldnt get it out.  Speedtest.net would report download speed of less than 100mnps and up speed of like 20mbps or less (I have a 500mbps plan up and down) so it looks very much like it got stuck in 100mbps mode internally!  The internet negotiating speed still reported a 1000 connection however.  I'm using a Samsung S22 phone and using speedtest.net app to test.  When this happened, i would have to turn off the 5ghz channel>save>then turn on>save and it would be back to normal. This is repeatable 100% of the times and very annoying.  Please fix this bug!  Tks.
