Hardware Version:
Firmware Version:

The Range Extender becomes more and more popular nowadays with the demand for enlarging the Wi-Fi coverage area. But you may get in trouble to make it work. What can I do if I failed to configure my Range Extender? Today, we will show you several common situations you may encounter and how to deal with them. We will take RE450 as an example.

Note: RE is short for Range Extender.

Case 1: The initial configuration of RE.

Please follow the instruction mentioned below to configure your RE.

  1. Please refer to https://www.tp-link.com/support/faq/1400/.
  2. You can watch the setup video as well.  https://www.tp-link.com/support/setup-video/

Note: Please use the main router’s Wi-Fi password to configure the RE. And the Wi-Fi password of RE cannot be customized.

 

Case 2: Failed to connect it to the main router: Signal LED/2.4GHz/5GHz LEDs are off. Or you will see the picture below after logging into the web UI.

What can I do then?

  1. Ensure that you entered the correct Wi-Fi password of your router during configuration.
  2. Hold the reset button/hole for 3s and reconfigure it. You can refer to Case 1.
  3. Disable Mac filtering/Access Control/Band Steering functions on the main router.
  4. If it is still the same, please provide the information attached below:
  • The model number of RE, and its hardware/firmware version.
  • The model number of the wireless router/modem, as well as the hardware/firmware version.
  • A full screenshot of the status page on RE.  
  • You can start a new thread with the information mentioned above attached and then we can give you a specific answer.

 

Case 3: RE has connected to the main router: Signal LED/2.4GHz/5GHz LEDs are on but still no internet access.  

And you will see the Status page on RE shows as below: DHCP Server (On), Dynamic IP (Failed).

 

What can I do then?

First, the root cause is that the RE/clients failed to obtain IP address from Main router. A static IP and specific DHCP server settings on extender will sort this out.

A.Login to router and check the DHCP server settings on Router.  For example, below is the DHCP server settings on TP-Link Archer C7.

Or connect your PC to the WiFi you want to extend. Start -> CMD -> Ipconfig /all. You can get  Subnet Mask, Default Gateway and DNS Servers values from there.

B. Customize the DHCP server settings on RE.  According to the settings on Router, RE’s DHCP server should be set as below.

C. If you have any further problems, be free to contact us by starting a new thread.

3.10 Edit: Add how to get the IP address, subnet mask, default gateway and DNS server for CASE 3 - Step A.

@Kevin_Z i have tried everything you've suggested but it still doesnt work. The 5Ghz network keeps disconnecting and i have to reboot the extrender to regain access to the internet which is very annoying.

@M_ok 

 

What is the model number of your extender? What is the led status of it when it stops working? 

 

Do other devices connected to the main router have the same issue? Can you get internet from the extender via LAN cable at the same time? 

 

Please show us a screenshot of the settings page and the Settings-DHCP page if you are able to log into the web UI with extender stops working. 

 

Besides, what is the model number of the main router?

@Kevin_Z hello, I have attached the model number of the extender and the settings page. Just to reiterate, the 2.4Ghz works fine but the 5Ghz keeps disconnecting. I can get internet on the 2.4Ghz but not on the 5Ghz when it stops working. The LED is still on even when there's no internet. Thanks

@M_ok 

 

Thanks for your information. 

 

You can set up a static IP for the RE450 and turn on the DHCP server and configure the DHCP settings by referring to case 3 on the original post. 

 

Besides, what is the model number of your main router?

@Kevin_Z so I think I figured a way out of this mess. I'm simply connected to the main router on 2.4G and extended on 2.4G and 5G. Now the speeds are not so fantastic but I'll take this over having to reboot my extender every 3hours or so. I haven't rebooted the extender in over 24 hours so far so it should be a good sign. I'll appreciate if there's a firmware upgrade to tackle this issue. Thanks

Hi @Kevin_Z 

 

I just bought RE450 and experiencing the anomaly problem.

 

Everything fine with 2.4G, but when extending the 5G it was ok for the first 60-120 minutes.

After that, all my devices had some issue connecting to Internet, Intermittent connection and then for the new devices cannot get IP addresses which connected to 5 Ghz SSID.

When I was connecting my devices to the 5Ghz host/root wifi router, all were good.

 

But here is the weird thing, I tried to not setup password (Open Authentication) for 5Ghz SSID in the host/root wifi router, as well as RE450. And everything were stable and normal for around 8 hours. But if I setup the password for connecting to host/root wifi router, it became unstable again after 2 hours.

 

I assume there is a defect/bug with the 5Ghz chipset corresponding to password encryption.

 

Thanks for your attention!
