Make sure you are connected to the COMFAST WiFi network when scanning the QR Code.

Please check the password is correct, if this doesn’t resolve the issue we suggest restarting the installation process by resetting the Extender. Copying the password into the password field is a good way to solve the password issue.

Please check WPS is enabled on your router, it is often disabled by default. Once you have set up WPS, you still need to enter the password by connecting to the WiFi  extender network (PLUS)

It is likely that your extender is placed at the borderline of the signal range covered by your main WiFi router. Moving your extender closer to the main WiFi router will most likely resolve this.

Yes, you can use as many as you like. If you are extending the network, then you may experience a slower speed as more repeaters are used.

In general, COMFAST wireless extenders are “universal” extenders. This means that they are compatible with the vast majority of wireless routers on the market, whether purchased separately or provided by an ISP.

Some important considerations regarding compatibility of wireless range extenders:

Some Wi-Fi extenders operate on both the 2.4 GHz band and the 5.0 GHz band. If your Wi-Fi router only supports 2.4 GHz, the extender can of course still be used, but performance may vary depending on which band is used.

The wireless device MAC address is translated to another MAC address when the wireless device connects to the extender.  To allow the wireless device to connect, you must add the translated MAC address into the router.
To get the translated MAC address:

  1. Disable the MAC filter on your router.
  2. Power on the extender and connect desired wireless devices to the extender.
  3. Make sure that the Link Rate LED remains lit.
  4. Log in to your router and check the connected devices on the Attached Devices screen. Add all MAC addresses including Virtual MAC (begins with 02:0F:B5) into your router’s MAC filter table.
  5. Enable MAC filtering on your router.

The first 3 bytes of MAC address is translated into 02:0F:B5 as mentioned above. Please log into router and add translated MAC addresses into IP reservation list.

No WEP is not supported try changing your router security mode.

Make sure that the passphrase you entered on your wireless device is correct, and power cycle the extender and your router. If your device is still not able to get the IP address:

  1. Move the extender closer to your router, and move your wireless device closer to the extender.
  2. Disable the wireless interface and enable it again to see if your wireless device can get the IP address.
  3. If your router has a MAC filter (wireless access control), disable it and follow the FAQ to add the device’s MAC address to your router.

Try to change the wireless settings of the main router. You can also try a new network name and password.

During the initial connection stages, the gateway generates a different WPS implementation which may cause wireless devices to be unable to connect to the WIFI Extender. If you are unable to connect to your Extender, please reset the device by holding down the reset button for 10 seconds.

WPS supports WPA/WPA2 security, if your Router is using WEP security you will need to walk through the Extender setup.

You can have more than one Extender connection to your Router network, however you cannot daisy chain your additional Extenders. Daisy chaining is not officially supported and will affect performance for client devices connected to the second Extender in the chain.
