I've been using my orbi ax6000 for a few months, and mostly love it.
My one issue is that I regularly have to reboot my xfinity router due to local slowdowns. Whenever I reboot the router, it takes almost 30 minutes for the ORBI wifi network to allow device connections. The light on the unit stays purple for the entire process.
Seems incredibly long to be down for a simple router reboot.
