Hello,
If you are looking to use PPPoE wired WAN as your main internet source, then you will need to configure the WAN interface for PPPoE.
You can do so by accessing the WebUI of your device. Configure PPPoE by editing WAN settings in Network -> Interfaces -> edit WAN. There, select PPPoE as the protocol and set other required parameters, such as a username and password. You can find information about interface settings here.
To ensure that this connection is your main connection for internet access, drag this interface to the top so that it is the first interface in the list. This will ensure that this interface is a preferred interface for internet access.
In case you want your RUTX50 to use a different access point (a separate device) for internet access, you can configure RUTX50 in wireless
client mode. This way, RUTX50 will connect to an access point, and all devices connected to the LAN network of RUTX50 will be able to access the internet via this access point. I suggest watching our YouTube video here.
This configuration will create an additional interface, similar to the WAN interface for the PPPoE. You can then arrange the order of these interfaces as you wish, as described previously.
If you want to use a PPPoE connection as your main internet source and swap to a wireless WAN connection only when PPPoE becomes unavailable, you can configure failover. With failover, when the interface with higher priority (lowest metric) loses connectivity, the next interface in the list takes over to ensure connectivity.
Kind Regards,
