I own 2 X55 v1.0 routers which are at 2 different locations. I am able to see both through the Deco app. This week I received a message that the X55 router that is at the other location was updated to firmware 1.5.5. I decided to do a manual firmware update on the router that I have at my location and noticed that it would not update.  It just said I had the latest version.  I checked the support site and noticed that after my current firmware of 1.5.1 there had been another firmware release v1.5.3 I am not sure why the router is not recognizing that firmware and why my other router is able to do an auto update. I am thinking that firmware v1.5.1 must have broke the that function on my current router.  So I changed the settings to do an update update at a specific time that I am asleep at and it still did not update. Today I decided to update my router's firmware manually instead by downloading the file and upgrading it through the routers gui.  I am now on v1.5.3.  Not sure how my other router got v1.5.5 but it is definitely not listed on the support site. I have also seen other owners say they have received a firmware update on a different model to only find that firmware is not listed on the site and that only 1 router is updating while the others are not.

Any ideas how I can fix my router to accept a manual update of firmware when I use the deco app or even auto update?  I like to have this feature working again please.
