Karta zmieniona, ale

Mam karte USB - mt7921u usb  COMFAST CF-926AC V2, sterownik ktory sie laduje

Powinno byc tak:

| radio0: lan, mode: ap, ssid: L340virtual, channel: 1, conn: 0             |
| radio1: lan, mode: ap, ssid: L340virtual, channel: 36, conn: 0 

A niestety dziala albo 1 czyli 2.4G albo 2 czyli 5G

Mam WIFI config - podejzewam ze jest blendny option path, przy wifi config tworzy mi sie tylko 5G z palca probowalem dodac 2.4 ale z tym samym ciagiem (wiem ze 2 option path powinien byś inny odwolywac sie do 2 radia)

config wifi-device 'radio0'
    option type 'mac80211'
    option path 'pci0000:00/0000:00:15.0/0000:03:00.0/usb4/4-1/4-1:1.0'
    option channel '1'
    option band '2g'
    option htmode 'HT40'
    option country 'PL'
    option cell_density '0'
    option noscan '1'

...

config wifi-device 'radio1'
    option type 'mac80211'
    option path 'pci0000:00/0000:00:15.0/0000:03:00.0/usb4/4-1/4-1:1.0'
    option channel '36'
    option band '5g'
    option htmode 'VHT80'
   
   
   
Mam 2 x

phy0-ap0

a pominno byc

phy0-ap0
phy0-ap1

Pewnie bedzie dzialac jak sie zmieni

option path 'pci0000:00/0000:00:15.0/0000:03:00.0/usb4/4-1/4-1:1.0'

Ale co zmienic i gdzie nie mam pojecia

tego nie wim, ale skoro tak mowisz to pewnie tak jest, na to bym nie wpadl, podejzewalem, ze moze tak byc.

no niestety, a jaka moze byc przyczyna tego ze tel nie dostaje mi dhcp tylko musze ustawic recznie getway - znaczy dostaje z DHCM ale nie ustawia sie getway automatycznie. A z karta niestety sa 2 bandy

dzieki za pomoc

Do AU są normalnie w openwrt dostępne. Z niektórymi kartami działa, z niektórymi nie, sam przetestuj czy z tą którą masz zadziała.
