BPI-R3 Linux 160MHz Bandwidth

Hey, has anyone got 160MHz Bandwidth working on non OpenWRT Linux? As soon as i switch to he_oper_chwidth=2/vht_oper_chwidth=2 DFS can no longer start with:

nl80211: Failed to start radar detection: -16 (Device or resource busy) DFS start_dfs_cac() failed, -1

80MHz Bandwidth on the other hand works fine.

Which image and which kernel version?

I’m no expert in wifi settings but maybe mt76 driver does not yet support MODE_11AC_VHT160 for r3 wifi chips. You could try using some recent kernel (6.4 or 6.5-rcX),maybe there is now support for it.
