Troubleshooting Has connected to TP-Link extender but no internet, what can I do?
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.
Case 1: The Initial Configuration of Range Extender
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 to the Main Router or Errors out ‘No Host Network Connection: 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. Verify the Wi-Fi password of the main router:
1) Log in to the management page of your router and double-check the Wi-Fi password.
2) Or forget router Wi-Fi network on mobile device temporarily , connect back to router Wi-Fi by putting in password manually to examine Wi-Fi password.

2. Factory reset Range Extender and reconfigure
RESET: With the extender powered on, use a pin to press the RESET button (pinhole) until all the LEDs flash once
3. Disable Mac filtering/Access Control/Band Steering functions on the main router.
4. For Dual Band Range Extender, if the App or Web says ‘ No Host Network Connection ‘, check if router 5Ghz Wi-Fi is on DFS channel ( Brief introduction of DFS function) change Router 5G channel to Band 1 channels (36, 40, 44, 48) and set up RE again
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?
1. 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.
1) 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 Wi-Fi you want to extend. Start -> CMD ->ipconfig /all. You can get Subnet Mask, Default Gateway and DNS Servers values from there.
2)Customize the DHCP server settings on RE. According to the settings on Router, RE’s DHCP server should be set as below.
If the issue persists despite the above steps, please Start a New Thread for your range extender with the troubleshooting steps you've tried and we'd love to look into that further:
1. LED status on RE
2. Model of router and network topology, e.g. Router AX1500 <wireless> RE450
3. Try to log in range extender web page and share a photo of Status page after setup
4. Firmware and hardware version of RE: How to find the hardware and firmware version of my TP-Link device?
5. For dual-band extender, RE failed to connect to 2.4Ghz or 5Ghz or both Wi-Fi bands.
Thank you!

I am using extender RE450 in camp to get better wifi.
I have setup extender with no errors, but when I connect to extended network, nothing works. On extender all blue lights are on ..... 2,4 and 5ghz, but when im connected to this network I can't even access setup thru tplinkrepeater.net to see what is going on. I tried to reset it and setup again, but the same problem occurres all over again.
What am I doing wrong ?
