I got my EAP 225 a few months ago. it was working okay (I am not pleased with the speed but it was good enough and I didn't have time to troubleshoot the speed)

this week I got so much grief from the device I wanted to smash it on the floor.

aside from the wifi speed dropping to nothing before going back to regular speed, I been having this bizarre issue that dhcp are registered fine on one band (2.4GHz) but refuse to work on the second (5GHz).

can't figure this issue out. the DHCP is hosted on the router. why would lt work on one band and not the other?

I don't even know how to begin to troubleshoot this issue.
