Mode

If you want your router to have its own subnet, you need to choose WISP mode. If
you want to extend your existing network by bridging the mini router and your
current router wirelessly, you can use WDS.

You have to make sure your existing Wi-Fi supports WDS. Using WDS only if you know
what you are doing.

Using Repeater means connecting your mini router to another existing wireless
network, e.g. when you are using Wi-Fi in hotels or other public locations.

Choose Repeater mode in your Internet Settings and your router will
automatically search for SSIDs. Choose a SSID and input the Wi-Fi password.

GL-AR750 Router is a dual-band router; when it works as a repeater, you need to
make sure that it uses the same frequency as the existing router does.

Saved Networks

The repeater manager will remember a list of your used networks in Save Networks.

When your current wireless network is out of range, the manager will find another

available one from the list and switch the Repeater connection to it automatically.

To disable repeater manager, uncheck the box Auto scan & reconnect on the Internet
status page. In Saved Networks, you can delete or choose one from the list to
connect.

Using above DIY features might have a risk of bricking your router. We have no obligation to provide support, maintenance, upgrades, modifications,

or new releases on DIY features. We reserve the rights of interpretation on above DIY contents without further announcement.

Our firmware is developed based on OpenWrt / LEDE and you can download all the firmwares from our

website: www.gl-inet.com/firmware. Find the available firmwares from the folder according to your
device model, and they are located in different sub-folders:

v1 folder contains release versions. It should be the default firmware shipped with the router.
clean folder contains clean versions of OpenWrt / LEDE firmware, with Luci software only. By default, Wi-Fi
is disabled and you need to enable it in Luci.
tor folder contains Tor firmware for the device.

GL-AR750 does not have an official DDWRT firmware now and it might be avaiable in the future. For further

information, please visit https://www.dd-wrt.com

GL-AR750 does not have a Tor firmware now and it might be avaiable in the future. For further information,

you can refer to our online tutorial at www.gl-inet.com/docs/openwrt/tor/

If you have sufficient technical skills, you can compile your own firmware and flash to the router. Please

refer to our online docs at github.com/domino-team/openwrt-cc

If you flash the wrong firmware, you would brick your router. But you still can recover it by using uboot

failsafe. Please refer to the guide at www.gl-inet.com/docs/diy/uboot/
