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'
