OpenWrt
Model    TP-Link Archer C7 v2
Firmware Version    OpenWrt Chaos Calmer 15.05 / LuCI (git-15.248.30277-3836b45)
Kernel Version    3.18.20

Wifi G now appeared, but I have three visible Radios.

I think one of these Radio is configured wrong.

Qualcomm Atheros QCA9880 802.11nac (radio0)

Qualcomm Atheros QCA9880 802.11nac (radio1)

Generic MAC80211 802.11bgn (radio2)

It's working but the Radios here I think is wrong.

Thanks!

I have found LuCI can get confused sometimes as the /etc/config/wireless file is generated before you install the 802.11ac package ath10k, which means the order the WiFi chips are detected then changes when you reboot.

You can either delete the interfaces in LuCI then add them back, so they will be picked up in the right order.  Or SSH into the router and delete the /etc/config/wireless file, then run wifi to regenerate the file with the devices in the correct order.

A third option is to edit the /etc/config/wireless file and change radio0 to radio1 and what was radio1 to radio0.

Could someone provide me with the cmd line to delete or edit?

Thanks

I've updated my post.

This removes wifi settings and generates new config file with defaults:

rm /etc/config/wireless
wifi detect > /etc/config/wireless

"vi /etc/config/wireless" for hard way.

Thanks, it worked!
