Check the exact device

Menu names and behavior can vary by US hardware revision and firmware. This guide was researched from official material, not tested on a physical router.

Applies to: GL.iNet Slate Plus GL-A1300 Wi-Fi 5 travel router behind hotel or short-term rental Wi-Fi.

Official evidence: GL.iNet Slate Plus GL-A1300.

Before you begin

  • Confirm the venue permits a travel router and that any captive portal login follows its network terms.
  • Keep all VPN credentials private and use only the local manufacturer admin panel.

What to check / do

  1. Power the GL-A1300 using a compliant USB-C 5V/3A source and complete local administrator password setup.
  2. Join the hotel guest Wi-Fi using its vendor-supported repeater/client mode; validate the hotel captive portal using a connected device before assuming VPN is at fault.
  3. Check internet without VPN first, then add only a supported WireGuard or OpenVPN profile in the local router UI.
  4. If VPN connects with no traffic, inspect policy routing, DNS and captive portal state rather than resetting firmware.
  5. Use the local dashboard to verify which connected devices are assigned to VPN policy; a hotel access point is still the upstream network.

Verify the result

  • Internet works through the travel router before VPN and, when configured, through intended VPN route.
  • No passwords, VPN private keys or portal tokens were entered on RouterFix.

If the result is not what you expected

  • Stop changing settings if you cannot identify the model or a reliable administrator recovery path.
  • Use the exact manufacturer support link below and quote your hardware label, firmware version, and what changed.

Restore / undo

Disable VPN and repeater for testing, disconnect the uplink and restore original travel-router saved profile as needed.
