I opened a case with ASUS Support and they suggested downgrading to the version before this one. I didn't even try because I thought it was impossible. I'm running v37103 now. Still seeing the deauth messages but hoping the wifi crashing stops.
I have this same issue except I have to restart the router for wireless devices to reconnect. Wired devices are unaffected. This started with update 37963 on 3/23. I tried hard resetting and restoring settings but this did not help.
