TROUBLESHOOTING
 

1.  What should I do when I cannot get the Linksys RE6400 connected to the router or access point?

Here are some things you can do to check the position of your router and extender:
  • Make sure you are using the same WiFi name and password as your existing WiFi router or access point.  The WiFi password is case sensitive.
  • For first-time setup, you may need to place the extender closer to the router.  After you’ve set up your extender, you can unplug it and move it to the final location.
  • To reduce signal obstructions, try alternate locations for the router and extender.
  • Avoid placing the router and extender near metal objects, masonry walls, and reflective surfaces, such as glass or mirrors.
  • Avoid placing the router and extender near other electronics that may cause signal interference.
  • If you’re using WPS to connect, wait until the WPS indicator stops blinking before trying to make the connection again.


2.  What should I do when I cannot access the web interface of the Linksys RE6400?

If you cannot access the Linksys RE6400, try any of the following troubleshooting methods (make sure your computer is connected to the extender’s WiFi name):

  • Use the friendly name of the Linksys RE6400:
  • For Windows:  http://RE6400-xxx
  • For Mac OS X® and iOS devices:  http://RE6400-xxx.local

NOTE:  xxx represents the last three characters of the MAC address.

  • Use http://extender.linksys.com – To use this, make sure your computer is connected directly to the range extender with an ethernet cable.  If your computer is WiFi ready, make sure it’s connected to the SSID with the -ext extension.
  • Use the range extender’s IP address, which is http://x.x.x.x –   If the range extender is not yet configured, its default IP address is 192.168.1.1.  Once the Linksys RE6400 is connected to your existing network, it will detect a DHCP server in your network, like your WiFi router.  Your WiFi router will automatically assign a different IP address to the range extender and treat it as a DHCP client.  Therefore, the default IP address will change.  You may need to check the DHCP client list of your router.  To do this, click here.
  • If all links above do not work, then try the following:
  • Powercycle the range extender.
  • Move the range extender closer to your router.
  • Look up your range extender’s IP address on your router’s DHCP table and try to ping it.
  • Connect your computer to the range extender’s LAN port and attempt to access it via the default IP address and check the WiFi settings.
  • Reset the range extender to factory defaults and go through the setup again.

3.  What should I do when I experience intermittent connection issues when connected to the Linksys RE6400?

Ensure that your range extender is getting at least 50% of your router’s WiFi signal and is located midway between your router and the area without WiFi.  Log in to the Spot Finder page and determine your signal and move the range extender according to the Spot Finder results.
