Fixing Wi-Fi Connection and Captive Portal Failures

Older Broadcom Wi-Fi cards patched via OCLP on macOS Sequoia often fail to redirect to Captive Portal login pages (like hotel or public Wi-Fi).

Solution Steps:

  1. Turn Off Private Wi-Fi Address: Go to System Settings → Wi-Fi, click Details on your network, and set Private Wi-Fi Address to Off.
  2. Force Login Page: Open Safari and navigate manually to http://captive.apple.com or 192.168.1.1 to force the login prompt.
  3. Verify OCLP Network Patches: Open OCLP and verify if the Modern Wireless patch is applied correctly.

Original Question: "Captive portal protected wifi broken"

So I've recently installed macOS Sequoia on a MacBook pro 2017 13 inch with touchbar, and it works wonderfully, however I am unable to use any captive portal protected wifi networks (tested with NS free wifi in the train) on my phone it connects, prompts me to accept the agreement and then it works, but on my Mac it just connects without even giving me the option to open the captive portal and so I never end up having wifi access, despite it showing connected. Additionally it safari it specifically says "this mac is not connected to wifi" and Firefox says to check my internet connection
