k2p ac2100 mtk7621使用openwrt官方固件无法启动双频WIFI的解决办法

具体什么操作顺序我也忘记了。

忘了先开radio0还是先开radio1，然后选N模式，第二个选AC模式。

但是有个简单的办法就是修改配置文件：

密码1234567890

config wifi-device 'radio0'
    option type 'mac80211'
    option path '1e140000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0'
    option htmode 'HT40'
    option band '2g'
    option channel 'auto'
    option cell_density '0'
 
config wifi-iface 'default_radio0'
    option device 'radio0'
    option mode 'ap'
    option ssid 'OpenWrt-2G'
    option encryption 'sae-mixed'
    option key '1234567890'
    option network 'lan lan_ipv4 lan_ipv6'
 
config wifi-device 'radio1'
    option type 'mac80211'
    option path '1e140000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0+1'
    option band '5g'
    option htmode 'VHT80'
    option cell_density '0'
    option channel 'auto'
 
config wifi-iface 'default_radio1'
    option device 'radio1'
    option mode 'ap'
    option ssid 'OpenWrt-5G'
    option encryption 'sae-mixed'
    option key '1234567890'
    option network 'lan lan_ipv4 lan_ipv6'
