AC86u 5ghz random issue

[telUK]

Hi

I have a random issue, although rare with the 5ghz band on my ac86u running merlin firmware.

All my devices will lose the wifi that are on the 5ghz band.

Yesterday evening I noticed playing online game (BFV) that after a minute or so my game would lag extremely with my ping increasing to 999.
The 5ghz band would then drop altogether, weather these issues are both connected, Im not sure, but previous to this, all online gaming has been fine.
I also checked my iPad connected on the 5ghz band and that had lost its connection as well.

The 5ghz band seems to come back online on its own, but I reboot as well just to be sure.

I'm in an area that I would not say is congested with wifi 5ghz signals either.

I'm just lost on what could be the cause of this happening every now and again.

Thanks

Look in the router's syslog to see if there are any messages at the time of the problem.
