@mariak It appears Omeda controller has hijacked my switches, even bore adopting them and changed both to the same IP (???): 192.168.0.1. I thought UniFi controller was bad.... I'll stick with CISCO...

@Emitplink A noob question. I have just installed omada controller 5.0.15 and adopted two switches (TL-SG2428P 1.0), then decided to remove them. I selected Forget option. Now, I'm unable to access...
