both 380.7743 and 382.18991 with random reboot issue.
upgraded from 7443 to 18991 then downgrade back to 7443 again.
all upgrade and downgrade comes with factory reset , no added on USB devices or running any built in features.
it just apple and android phones connecting via Wifi (less than 10 devices in total) + one PC running on LAN.
i would say less streaming in my case , maybe some watching of videos on youtube.
no on going BT download.
Using N12 D1 and N12HP previously without any issue , but of course that is not an AC router
Will try to do some changes on Wifi setting , and see if it works.
meanwhile wait for Asus representative feedback
