Changing the operating mode and role of network ports

A Keenetic router provides flexible settings for network ports of the built-in Ethernet switch. For example, you can change the operating mode of a particular port (manually set speed, duplex, or disable it), change the purpose of the port (e.g., use one of the LAN ports as a WAN port, or vice versa, use the WAN port as a LAN port).

1. changing the port's operating mode (speed and duplex parameters).

This feature may be required for compatibility with the connected network device.

On the 'General system settings' page in the 'Network ports' section, you can manually set the operating mode for each network port. By default, the Keenetic router's built-in Ethernet switch uses automatic detection of connection speed and cable type (duplex mode). If necessary, the speed/duplex settings on the Ethernet port can be set manually.


2. Assigning one of the LAN ports as a WAN port.

For example, such a task may be required if the main WAN-port of the router is inoperable. You can assign a WAN port function to one of the free LAN ports. To do this, go to the 'Wired' page, in the 'Connection and VLAN' section, select a free LAN port (in our example it is port 1) and specify the value 'Provider' for it, which will determine the operation of this port as a WAN port.


Save the setting and connect the ISP's network cable to this port.


Then make sure that Keenetic has received an IP address from your ISP (established a connection). On the 'System dashboard' home page in the 'Internet' info panel, the IP address will be displayed in the same way as when the ISP cable is normally connected to the main WAN port.

TIP: Note: Keenetic routers support multiple simultaneous connections (usually called Multi-WAN). For example, you can connect two Internet Ethernet cables from different ISPs to the Keenetic at the same time and set up basic connection redundancy. All Keenetic routers without exception support Multi-WAN. For information on how to configure it, see the article 'Using more than one ISP: redundancy and multi-WAN'.

3. Using the WAN port as a LAN port.

For example, such a task may be required for routers that use a 3G/4G USB modem as their primary and only Internet connection. The WAN port 0 of the router is not used, but it can be configured to connect home network devices, i.e. it can be used as a regular LAN port and thus increase the number of home network ports. For example, in the Keenetic 4G router (KN-1210) only three network ports are designed to connect home devices, and the following actions can be used to add a fourth LAN port.
Since this example does not use the main WAN port 0 of the built-in switch (using an Internet connection via a USB modem), the wired connection to the ISP must be deleted. Go to the 'Wired' page and click 'Delete connection' (located at the bottom).
After that, the WAN port 0 will be automatically included in the Home segment, i.e. it will become a regular LAN port, and you will be able to use it to connect home devices via Ethernet cable. 


To check, connect the device to the WAN port 0. It should automatically obtain the IP address of the home network from the router.

You can restore the assignment of the '0' network WAN port (wired Internet connection) at any time by adding a wired Internet connection, or by resetting the router to its default settings.

To restore a wired Internet connection, go to the 'Wired' page. Click the '+' button (Add provider).


After that, the assignment of the WAN port 0 will be restored.


Go to the General system settings page to reset your Keenetic to the factory default settings. In the 'System reboot' section, click 'Reset all settings' (located at the end of the page).

NOTE: Important! All user settings will be deleted when you perform a reset.
