We’ve all been there, you are on some hotel guest Wi-Fi and you see the Wi-Fi connect, but then you can’t get an IP address, and the Captive Portal just isn’t getting triggered.
Here are a couple of solutions that might help trigger the HTTP the Captive Portal is looking for, instead of the HTTPS your client is probably defaulting to.

You can also trigger the captive portal by grabbing the IP address of the router from your wifi connection info and putting that in a browser.
