Well I know how to flash a router and do a basic setup, but sending commands with SSH is not my thing
My router should be just a wireless AP, nothing else
So after flashing Gargoyle I did a config as Gateway (Default) with WAn disabled. Then disabled DHCP and everything works fine now.
But I do not see the assign WAN port to LAN option.
When I go wireless bridge/repeater it's possible to bridge WAN to LAN
But I have to join an SSID and this seems just wrong because I don't need to repeat a wifi signal
