Why is my TP-Link Range Extender Not Providing the Same Speed as my Main Router?

The purpose of a Range Extender is to expand Wi-Fi coverage and connection stability in areas of your home. However, it is important to note that you may not be able to achieve the same speed as the main router when you are using the Range Extender, due to elements such as distance and the characteristics of Wi-Fi technology. It is not uncommon to receive lower connection speed through the Range Extender when compared to the main router.

Here is a simple example of the above theory:

Network topology:

Note: All the clients are in the same position as the Range Extender

Due to the functions and protocol regulation of Wi-Fi technology, the more wireless hops, the slower the connection rate will be. When Client 1 is connected to the main router and Client 2 is connected to the Range Extender, Client 2’s speed will be slower than Client 1’s, as Client 2 goes through an extra wireless hop compared to Client 1.

However, there will be no speed difference if the client is connected via Ethernet cable to the Range Extender.

Overall, the speed relation of each client in the above topology is as follows:

Client 1 ≈ Client 3 > Client 2

Note: The above speed relation is only used for reference, as the actual speed will vary as a result of each device’s specifications and environmental factors, including building materials, obstacles, volume and density of traffic, etc.
