How I activate the 5 Ghz antennas so that the devices can access it and thus have internet. Since my free router I use it as an external access point and not connected in mesh
So late of a reply… more for completion.
In order to open a network on the 5ghz interfaces so devices can connect to them you need to run the following command on your router (through ssh):
uci del_list lime-node.wifi.modes='ap_5ghz' uci del_list lime-node.wifi.modes='ap_2ghz' uci add_list lime-node.wifi.modes='ap' lime-config lime-apply reboot
Can you verify @SAn?
It was replied in spanish here: ¿ Cómo activo las antenas de 5 Ghz?
The gist of it is what is described above.
