If you’ve configured the range extender step by step and LED lights are on but there is no internet or your extender is working but the connection is unstable, please try the following troubleshooting.

If you don’t know how to login to your router’s management page to check IP info, please refer to Method 1, otherwise, refer to Method 2.

Method 1

Please connect the computer to your main router with Ethernet cable or Wi-Fi,  then check the IP info of your computer, If you don’t know how to check the IP address on a computer, please refer here.

 

Configure the info on extender’s management page:

Method 2

First, please configure the range extender in a normal way.

Then check the DHCP configuration info on the router’s management page:

We take the TP-Link router AX1600 as an example(If your router is not TP-Link, you need to ask for help with your router’s support)

On this page, the IP address is the Router’s LAN IP

The subnet mask needs to be filled into the extender’s DHCP settings.

IP address (router’s LAN IP): 192.168.0.1                       

Subnet Mask: 255.255.255.0                                            

IP address pool: this range is set on the main router, on the extender, we need to set a smaller range than this one.

IP address pool (main router): 192.168.0.100-192.168.0.199

IP address pool (extender): 192.168.0.150-192.168.0.199       ③

All the info in red text, we need to configure on extender’s management page.

Finally, set on Range Extender

Block 2:

  • Fill with the info IP address pool (extender): 192.168.0.150-192.168.0.199 (Smaller than the router’s DHCP pool)
