but then i renewed DHCP lease (can be found on Advanced... > TCP/IP

and voila! it worked

Hi,

Having the same issue, I restarted using safe mode, the problem did not happen in safe mode.

I then restarted normally and now everything is OK.

Further to the information above, the Setting/Network Wifi status indicate it is connected via IPV6 when the issue arise. Turn Wifi on and off reconnect to IPV4 and work again.

I had the exact same issue! The solution is so simple... read below instructions I've found elsewhere:

System Preferences > Network > and create a new Network Location (normally its says Automatic) and to re-join a known working wi-fi network.

And that's it!!

Have you tried booting in safe mode and then rebooting again normal mode? Works for me all

the time now. Location does not work for me. I am in a different hotel almost every night so this has to work for me

The only way, albeit tedious, that it works for me is to start in Safe Mode, connect to the network and then reboot. It is **** obvious the the network device driver when loaded in normal mode, is being overridden by another device driver? How hard is that to fix.

Tried almost everything here and found out it was a proximity issue! I had no problem connecting to the wifi after updating to Catalina but when I moved to my room (probably 4meters from the router) it went bonkers. Had the patch downloaded and installed (by connecting to a LAN), it worked for 2 days then acted up again. Decided to sit close to the router just for shikks and giggles and viola, connected to the wifi with internet instantaneously.

I've tried all the mentioned methods but I didn't worked. After that I just turned off brandmauer and now wifi works fine.

Thank you, hasan-x. I created the new network. Nothing happened, so i deleted it and selected automatic again. Problem solved. Variation on a simple reboot. Thanks again!

I performed a PRAM reset 3 times hold down opt-cmd-R-P and power. Listen for chime release power and repeat a couple times. Should work after that.

Nothing worked, but deactivating the firewall solved it for me.

Downloading the final version of catalina now. no beta's anymore.

hope I could help anyone

Starting in safe mode fixed the issue for me pretty annoying !

Hello and welcome to Apple Support Communities, Savas44.

If I understand your post correctly, your MacBook Pro is connected to Wi-Fi but Safari and Chrome can't connect to the server when you try to visit websites. I’d like to help.

Follow the steps in this article:

If Safari doesn't load a page or webpage items are missing

Let us know if that resolves this issue for you. 

Thanks for using the Apple Support Communities. Take care.

The only way it worked for me was to boot in safe mode the establish the connection and reboot. Seems like you may have to do this for every new network you attempt to join . A secure network that requires password access works fine! Anyway there was a patch released couple of days ago, I installed it hopefully would not have to do the safe mode anymore

Hi, none of the solutions worked for me but I found this method here https://poweruser.blog/macos-catalina-wifi-issue-captive-portal-broken-45610cc016b5

Basically you navigate through finders following this path  /System/Library/CoreServices/Captive Network Assistant.app/Contents. In my computer, once i found the Captive Network Assistant.app, I had to disconnect first from wifi, re-find whatever public wifi I was trying to join, and while my wifi icon is flashing I click on the Captive network icon repetitively to time it's opening with the connection of wifi. It might take a few seconds but then the login popup should come up if you timed it correctly. It has worked for me with different public wifis so far.
