Here’s What to Do When TP-Link AC750 WiFi Extender Is Not Working

Check the Signal Strength & Internet Connection

The TP-Link extender might not be receiving a strong signal. It could be the reason why your range extender is failing to provide internet connectivity. Placing the range extender near the main router will fix this issue.

The second reason why the TP-Link AC750 WiFi Extender is not working is the problem with the internet connection. The main router might not be getting an internet connection from the ISP or the connection speed might be too slow that it is getting hard to access the internet on multiple devices. To rule out this possibility, connect a single device to the router and access the internet connection. A better approach is to use the ethernet cable to check the internet connection on your PC.

If you are not able to access the internet, either way, contact your ISP.

Reboot TP-Link Extender

A reboot does the trick many times. You should apply this method too here. To reboot the TP-Link AC750 WiFi Extender, simply plug out the extender from the wall outlet for 5-10 minutes, and plug it back. Check if the problem is solved.

Update Your Range Extender’s Firmware

Your TP-Link AC750 WiFi Extender could be running an outdated firmware version, which might be triggering many problems. Even if you don’t face any problems, you should keep the range extender’s firmware up-to-date.

Here’s how to update the firmware version on your TP-Link AC750 Range Extender:

  1. Download the latest firmware version for your WiFi extender by visiting website.
  2. Open on your phone or PC on which you’ve just downloaded the firmware.
