FS#2650 - r7800 19.07-rc2 unable to change channel for AC #7531
Comments
adrianschmutzler: Is regulatory domain set (correctly)? |
kaxa: default settings: root@r7800:~# iw reg get phy#1 phy#0 |
pepe2k: @vadim please be more specific and at least provide what channel number and HT settings are you trying to use - not all combinations are possible and correct. |
kaxa: all default setting: when I channel change in luci change get rollbacked after shoort wireless blackout. this was found in dmesg during such change in luci: [529385.947125] device wlan0 left promiscuous mode If /etc/config/wireless is edited manually and router rebooted then AC wireless gets disabled. |
bjonglez: This indeed looks like a regulatory / DFS issue. Please select the right country, and tell us which channel you try to use. If you try to use a DFS channel, it's normal that it gets disabled on boot. |
kaxa:
in Luci when change channel number change actually never gets committed, when do manually in /etc/config/wireless and then reboot router comes up with 5GHz network disabled, after changing back to default channel 36 5GHz network is usable again.
please provide steps to collect log
in dmesg only:
(wlan0) entered blocking state (wlan0) entered disabled state
