Common issues and troubleshooting steps 

Here are some typical problems that could happen when using the Linksys RE6400 to connect to the internet, along with potential fixes:

  • Dropped connections or sporadic connectivity

Solution: Ensure that the range extender is positioned far enough from potential interference sources and within an ideal range of the router. Make sure the router's firmware and the range extender's firmware are both current.

  • Accessing the setup page is impossible:

Solution: Make sure your computer or mobile device is connected to the network of the range extender and double-check the address you entered (http://extender.linksys.com or 192.168.1.1). Alternatively, try using a different web browser or deleting its cookies and cache.

  • The wrong Wi-Fi network was chosen:

Solution: During setup, double-check the Wi-Fi network you choose from the list of available options. Check to make sure you are connecting to your own Wi-Fi network and not one of your neighbors.

  • Network password incorrect:

Solution: During the setup process, double-check that you entered the correct Wi-Fi network password. Check the password one more time for typos and case sensitivity.

  • Little or No Signal Range:

Solution: Move the range extender closer to the router and to the location where you need better Wi-Fi coverage. Avoid obstacles and gadgets that cause interference.

  • Issues with incompatibility

Solution: Verify your router and range extender's compatibility. For optimum performance, make sure they support the same Wi-Fi standards (such as 802.11ac). Consider contacting Linksys support if compatibility problems continue.

  • Configuration problems with a router or an Internet service provider (ISP):

Solution: Check to see if there are any problems with your internet service and that your router is operating properly. Make sure that access points or range extenders can connect by checking the router's configuration.

  • Firmware Reset:

If all else fails, reset the range extender to factory defaults by pressing and holding the reset button for roughly 10 seconds. Then, configure it once more using the correct procedures.
