I have no issues.
Have 3 pc....2 laptop.......2 ps5 ......5 Smart TV ....and 1 nas on the 2'5 lan port.......and all work correctly.......
No problems since the last firmware.....
Good and stable router in my opinion
AC-86U +1
Im stuck on 2066 now......and no update
Change wan dns for 3 times with the same result....no refresh signature....(seems like "trend" issue..... i hope)
RT-AC86U 384.12 Over 384.11-2
reboot, causes the loss of qos parameters (classification) in custom mode.........in my case.
no error message in syslog..........:confused:
The router needs time to implement changes correctly.........
Update firmware and wait 5 minutes before restarting or restoring.......
P.D: Sorry for my English.....:(
Same problem on rt AC86U..........
Solved giving time for the implementation of the new firmware between........restorations..... restarts and implementations of qos...........5 minutes approximately in my case
Now all works fine
