Wifi does not recognise captive portal after upgrade to Catalina

Ever since I have updated to MacOS Catalina, the wifi does not recognise some captive portal based wifi networks.


The wifi appears to connect OK and is assigned an IP address, router and DNS server, so DHCP is fine, but the floating window with the normal login details doesn't appear. If I navigate to the router IP address in my browser, sometimes it will show the login page but entering the required details fails to activate the Internet connection.


Anybody got any ideas for a fix?

There is already an ongoing discussion


Maybe some of the tips over there will help you. For me it did not work out :(


I even had a one hour long call with @AppleSupport. Unfortunately even they could not help.

There are Mac viruses out there. https://www.macworld.co.uk/feature/mac-software/mac-viruses-list-3668354/


You are somewhat naive if you believe Macs to be invulnerable. Whether AV software is an effective solution to the problem is questionable. Certainly Avast shared many of the characteristics of malware.


Unfortunately, as long as lists exist like the one I linked to, "there are no Mac viruses" is not a good answer to the people conducting the security audit.

That article that listed a number of Mac vulnerabilities and that proves the statement "The honest answer is there are no Mac virus' out in the wild that can attack your Mac" is hopelessly naive? That article?


It may be that all the ones listed are no longer a threat (and, yes, some of them never really were), but they do exist and some were real threats until they were blocked.


You also forget about the use case of accidentally passing Windows viruses on to customers. I work in an organisation where some people use Windows. If their PCs were infected and they gave an infected file to me to distribute to a customer, it wouldn't be too clever.
