Ventura network/internet problem -- Please help!

[ItsAShaunParty]

Hi Everyone!

Just updated from Monterey to Ventura 13.6. 27" 2020 iMac.

I thought it was safe. I thought wrong. Issues include but are not limited to:

1. The internet wasn't working at all until I disabled Little Snitch
2. The internet still isn't working for some apps like the Messages app/iMessage (can't send images).
3. Other messaging apps like WickrMe and Keybase don't connect.
4. My 2.4 wifi connection is about 1 mbps. Usually, it's over 150 at least.
5. I can't find my printer on the network.

Anyone know a fix?

Thanks!

Thanks! Worked great!

If someone else is having this problem...

When I went into settings and clicked "Details"to turn off the iCloud Private Relay, nothing happened. So skipped ahead and reset the network settings.

I restarted my computer once and after the OS loaded, it froze. That was very odd. So I restarted again, and now everything seems okay.

I still have to reinstall LS, but I'm hopeful.
