Hello,

I have the Deco X60 v3.20 (x3 units).

Few days ago, I got the update 1.4.0 build 20241212 rel.48194 via the TP Link Deco App and besides the mentioned issue which breaks 160Mhz Channel width selection. it also breaks the the lan devices which are no longer show up as "wired" connection and basically wired devices no longer showing up.

I also tried the beta firmware mentioned here (1.4.0_build_20250805_Beta) but it doesn't seem to solve any issue.

Kindly waiting for update which fixes most issues. 🙏
