Little snitch uninstaller broke WiFi (Catalina)

[poohat1000]

Tried to uninstall LS. Restarted. Ever since my WiFi connects but shows the exclamation mark, it seemed although I wasn’t getting an ip from router so I logged into the router w my phone and saw it had designated an ip for the MacBook so copied that in manually- computer now says it’s connected (green light) but won’t work (still ! on WiFi logo in menu). I also can’t join my phones tethering - nothing will work.
Have tried deleting prefs files.
Replaced hosts file w the default
Reset pram
...nothing. Never a problem until I uninstalled LS
Any ideas ?

Try creating a new "Network Location" in System Preferences > Network.

If that does not work try reinstalling macOS Catalina over your existing Catalina you won't lose you app-data etc but might fix the wifi

I’m having the same issue, did you get a resolution?

Wifi works fine on my windows 10 boot camp install, not on macOS.

I can connect to my network devices via wifi (My unraid NAS and router), but it won’t assign an IP and gain internet access on MacOS.

Attempts to resolve
- Upgraded from Catalina 10.15 to Big Sur 11, nothing
- Made a new network location in System Preferences > Network as Heralds suggested above

I might try reinstalling little snitch and uninstalling again on Bigsur.

Hi,

ran into the same issues. Currently on Ventura.
Solved the problem when removing Little Snitch Filter. Go to System Preferences>Network>VPN> remove the Little Snitch filter from List.

Best regards

Also in the same boat.
Also on Ventura.
Removing the LS filter did no good here I'm sorry to say.
