Hello All,
I installed the latest 19.07 rc1 version on my router and I'm having 5ghz wifi drop, the interface works for some days and the suddenly the radio0 is completely disabled (Marvell 88W8864 802.11acn) and never comes up again, after some router reboots it eventually comes up again but at this point is unusable.. similar issues happened with dd-wrt and with the official Linksys firmware it works quite stable but really slow..
Is there a chance to troubleshoot the behavior of the faulty interface?, could be that the interface itself is broken?
Thank you in advance.
Cheers,
tmomas

option channel 'auto'
What happens if you change this to channel 36?

Hi, just as follow up, after one week testing in channel 36 the connection is much more stable, I just had to reboot the router yesterday only due to the wifi in general (2.4 and 5ghz) was behaving strange, the rest is working fine with the proper speeds. Thanks for the help!
