Repeater (WISP)

Note: Please check the Repeater Manager function

Using GLi mini routers, you don't need to have an Ethernet cable to surf the Internet, you can user it as repeater. The most common one is WISP (Wireless Internet Service Provider).

In WISP mode, the mini router act as a firewall and protect you from outside. If you are using a public wifi, you need to use this mode.

In the following diagram, your main router has an IP Suppose its netmask is, your mini router will have two IP address: which is got from your main router which is created by itself

So all your devices connected to the mini router will be protected by the firewall.


First Click Repeater tab in Internet Settings, the router will search for the available SSIDs around automatically. Then choose the one your want to repeat and type your password. The Mode should be WISP, then click Submit.


Repeater Bridge (WDS)

In other circumstances, you want to connect to your own router which you trust. You don't need a separate network, you can use Repeater Bridge mode. The most common one is called WDS. To use this mode, your main router has to support WDS. Consult your main router's manual to check if it has this options.

In WDS mode, the mini router only boost your main router's signal area, not creating a seprate network. There is no firewall between the mini router and the main router.

To use WDS repeater, ensure your main router support WDS, then choose WDS from mode list. You will have an option to input a static IP, which will be used to access this mini router.

If you know the subnet of your main router, for example in this case it is 192.168.1.x, you can input a static IP, e.g. This static IP should not conflict with any other devices' IP address. Then later you should access this UI at

If you are not sure, just keep the IP address blank so that it will get a IP address from your main router automatically. But you need to find out this IP in your main router's admin UI if you want to access this UI again.


Repeater Bridge (relayd)

In case you are having an old router and it doesn't support WDS, you can use WISP mode then setup a relayd overlay.

Here is detailed instructions of how to do it.
