What Causes the TP-Link WiFi Extender Red Light Issue?

If you are facing the red light issue on the TP-Link WiFi extender then that means your extender is having trouble getting a Wi-Fi network. This generally happens when there’s some bug in the router or when your router is far from the Wi-Fi’s range. 

Apart from this, the issue can also be encountered when the firmware of the extender is corrupted or outdated. Sometimes, the issue can be due to the router itself and not the extender.

So what can be done if my TP-Link WiFi extender is showing a red light? Given below are all the ways to help you fix the TP-Link WiFi extender red light issue-

1. Place the Extender in an Appropriate Place

When you install a Wi-Fi extender you need to ensure that it is getting a proper Wi-Fi network to extend it further. One of the key aspects of installing a Wi-Fi extender is knowing where to place it.

The extender must be installed at a place where your Wi-Fi signals are optimal. Your extender must be able to get the Wi-Fi signal so that it can extend it to other places in your house. 

Not only you must install it within your Wi-Fi range, but you must ensure that there are no obstacles or electronic devices in between the extender and the router.

Electronic devices interfere with the Wi-Fi signal and your extender may show the red light issue due to this. 

2. Ensure there’s No Issue With the Router

Sometimes the issue can be encountered due to your main router. If your main router is having issues then your extender will not be able to extend the Wi-Fi signals and show the red light issue.

You must check that your router has proper network connectivity if you have been facing this issue. 

You can directly connect to the router and see if you can use the internet. If you are not able to use the internet when directly connected to the router, then there’s no issue with your extender but your router. Check the wires connected to the router.

Ensure the wires are properly connected and not damaged. 

If you still face the network connectivity issue with your router then contact your ISP to get the issue troubleshooted.

However, if you can use the internet when directly connected to the router but facing issues with the Wi-Fi extender then you should try the troubleshooting steps mentioned in this article.
