Hi, I recently purchased the Deco X3000-5G router with firmware 1.1. 7 Build 20240809 Rel. 18610 I can't manually set the Channel to 5Ghz or 2.4Ghz, it gets stuck on CH6 where there is an analog signa

Where did this X50-5G firmware (1.1.7 Build 20240809 Rel. 18610) come from? I updated to it but it's not on the X50-5G firmware download page on https://www.tp-link.com/my/support/download/deco-x50-5g
