rmilecki: Your router has single PCIe device with two PHYs. That's why your devices in the /etc/config/wireless have paths "foo" and "foo+1". The problem is your iwinfo not understanding that. That has been just fixed with the commit 6e8475b ("iwinfo: update to the latest version"). Related to that is also commit e1d57d4 ("mac80211: rely on iwinfo for phy->path and path->phy lookups"). Once above fix receives some testing we'll probably backport it to the 21.02 release branch too. Meanwhile you could help by testing the latest master branch. |

Luci (git-21.160.71743-e3bf521) correctly sees configured channel but ignores 'option htmode HExx' for both radios (shows 'mode: legacy' for both radios, allows to choose AX and channel width from drop-down list and writes correct values to /etc/config/wireless when applying changes). HT and VHT modes are properly recognized. Iwinfo returns htmodes which seem ok:
root@OpenWrt:/etc/config# iwinfo radio0 htmode
HT20 HT40 HE20 HE40
root@OpenWrt:/etc/config# iwinfo radio1 htmode
HT20 HT40 VHT20 VHT40 VHT80 HE20 HE40 HE80 HE80+80 HE160
I have no AX clients so I'm unable to test these modes anyway.

jow-: The incorrect htmode preselection should be addressed by openwrt/luci@4286c84825 |

rgrgrg: LuCI Master (git-21.163.60157-1bcb125) correctly selects AX menus for HExx htmodes on both radios. Thank you very much. |

Autogenerated wifi configuration results in:
inability to set frequency in LUCI
channel analysis in LUCI shows only radio0 with incorrect frequency (radio0 is 2.4GHz, channel analysis shows chart for 5GHz)
iwinfo returns results only for 'iwinfo radio0 ...', but results are taken from phy1 (which belongs to radio1)

Enabling radios and editing files manually gives working configuration.
** Workaround **
Removing path and forcing correct phys makes luci/iwinfo happy.
