i was affected since Wednesday May 17th 3Am EST i was running 386.10 on my RT-AC5300 using my phone hotspot i first flashed the newest firmware which is 386.11 and had the same issue same thing for my node RT-AC86U. i got so frustrated plus family was working at that hour so i did a quick swap and brought back my old netgear R7000 and we were up and running, we use comcast i felt like the provided modem might be an issue too so i was busy on facebook market place to score a deal and get a motorolla MB8600. (P,S i dont pay modem fees with comcast so that why i had it for this long)
