Can't connect to Internet on MacBook Pro -Sonoma 14.1

What entering an all numeric IP address is supposed to do in a Pubic or Hotel Wi-Fi is force a web page access, which the service provider typically intercepts with their login page. Then you can enter your credentials and proceed.

Sometimes the Domain-Name Server access is also denied, but in some cases nothing (no log-in page) appears, and referencing an all-numeric IP address like 1.1.1.1 gets you out of that Rut.

If you have the green light in

System Preferefdnces > Network > Wi-Fi

Launch a browser and enter this easy to remember all-numeric IP address:

1.1.1.1     and press return.

If you get the CloudFlare** splash page, your internet is working, but DNS lookup may not be working.

**CloudFlare is NOT part of the solution, they just own the easiest to remember all-numeric IP Address.

All-numeric IP addresses do not require an "internet Phone number lookup" provided by your DNS service. the numbers shown in system preferences >Network >whatever-interface, e.g., Wi-Fi are the sites that will be asked for lookup.

There are no good:

0.0.0.0

your Routers local IP address, often 192.168.1.1

These are good:

the two numbers your service provider tells you to use

OpenDNS:

208.67.220.220

208.67.222.222

googleDNS, but I hesitate to provide them knowing google sells you searches and web site visits.

There are many more. If none of those work out, just post back.

hold down the Option key while you click on the Wi-Fi icon on the menubar.

from the menu select 'Open Wireless diagnostics.'

Click (Continue) to begin diagnosing your Wireless Environment and Configuration.

report anything it discovers other than

"Your wireless connection appears to be working as expected."

did you click (Apply) when finished?

did you check to see that the changes "took"?

are they still there after a restart?
