@GRL Oh ok. It's a shame because I've had this router for about 1 year. I bought it as a new device. I have to wait for the AX75 for example. thanks for the explanation.

Dear Helpdesk, AX10 at the 5Ghz support only 36-48 channels. I use last FW 1.3.1 Build 20220401 Rel. 57450(4555) When I used any wifi-analyzer, 5Ghz is full (lot of neighbors around me). Are you plan...
