Hi emac
Welcome to the forum, from what your describing and if this problem only started immediately after upgrading to Mint 21, it might be an IP conflict, try setting a static ip address in network manager also set ipv6 to ignored, bear in mind once you do that you will have to reboot the computer for the changes to take effect, if you're unsure how to do that post back and either myself or someone will talk you through it
Good luck
Graeme
