I happily unloaded my XT8 on eBay for pretty close to what I paid for it and no longer have to deal with the abortion ASUS calls a mesh system. Been out for months and still dealing with issues that should have been rectified a long time ago.
Im using a Amplifi Alien stand alone router and it covers a wider area with faster speeds than the XT8 ever did. No mesh required and it been rock solid for over a month without any issues. They actually pushed out a beta firmware update the same day the firmware bug was found by a user within a couple of hours of being notified.
