Zyxel WRE6505 [Range Extender] - Troubleshooting

This article aims to offer useful troubleshooting tips for resolving issues with the Zyxel WRE6505v2 wireless range extender. One key step is to check for available firmware updates. Updating the firmware can often resolve compatibility issues, enhance performance, and fix known bugs or vulnerabilities.

Firmware Upgrade WRE6505v2

  • Download the firmware to your computer
  • Log in to the web GUI of the router via http://zyxelsetup or http://zyxelsetup.local (for MAC) with the username (admin) and password (1234)

Note: If that doesn't work, then please try it with its IP address, which is either default 192.168.1.2 or an IP distributed by your DHCP server (router).

  • You will need to change the password upon the first login. Please change it to something you will remember in the future.
  • Navigate to Maintenance -  Firmware Upgrade

  • Click on "Browse..." and find the .bin file. Then click on Upload.

Note! If you have a .zip file, you have to extract it first before applying the .bin file.

  •  Wait until the router has restarted itself (not more than 10 minutes) and then refresh the webpage. Login again and double-check that the firmware version is updated (you can see it on the home screen of the web GUI) and you are finished.

Can't access the extender

This topic is a little bit broader, and we already have an article on how to access your device:
