I've found WiFi routers where I cannot open domains, but ping ip addresses just fine. This means I can't browse websites. This happens only on my Macbook, and these connections work fine for Windows laptops. How do I fix this?

I have two internet AP at my office, one is problematic, one isn't. I also have a wifi at home that works, but another wifi at my friend's house doesn't work.

**Details**

These tests were performed on the same machine. I can switch to either WiFi and this always happens.

Routers that are fine:
