  Adam HernandezAug 14, 2025
  If you're having trouble accessing the settings of your Buffalo Switch, here are some steps you can take: 1. First, ensure that your PC is properly connected to the switch. 2. Try accessing the settings using the switch's IP address, which is 192.168.1.254 by default. 3. Confirm that you are using the correct username ("admin" by default) and password ("password" by default). If you've forgotten these, you may need to initialize the switch. 4. If you have a proxy server configured in your web browser, try disabling it or adding the switch's IP address to the proxy server's exception list. 5. Finally, ensure that your PC is connected to the port that belongs to the management VLAN.
