Re: RB4011: wlan1 disabling itself

Looks like frame lifetime = 0.02 work fine. 8 days - all systems nominal :-)
Well. No good. After 14 days wlan1 disappeared again

Nope. Playing with channel settings still have no effect.

Re: RB4011: wlan1 disabling itself

I didn't change anything in config. Just upgraded routeros.

Re: RB4011: wlan1 disabling itself

I upgraded to 6.45.1 and 5ghz is running and visible for 3 days. It lasts only for 1 day before. Is the issue fixed? Can someone confirm?
Yep, running for 5 days or so. But maybe "adaptive noise immunity" disabling helped also.

Re: RB4011: wlan1 disabling itself


5GHz is falling due to the fact that the client starts to reconnect frequently.
So why it fails when there's no clients at all? After a long period of idle?

My observations show that rts/cts disabling may help. Still investigating.
