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'
