I have posted in Linux Mint forums but no luck yet. I have an HP mini PC running a media server on Linux Mint 21 and want to aggregate the wireless and wired LANs for resilience and throughput. I have seen a few suggestions that it can be done through the NM GUI but I can never see the wireless connection to add to a bond if I go down that route. I did find a thread on Stackexchange that said "NetworkManager GUI does NOT present wifi as an option with bonding" but that was for Mint 17 and goes on the suggest using the NM CLI but the later commands produce errors about the psk. I am pretty familiar with UNIX cli but to be honest just don't know enough about networking to modify the commands to suit my setup.

I know one or two people on here are tech gurus so - Can anyone help?

For reference, all the details of my setup are included in my Mint forum post here - https://forums.linuxmint.com/viewtopic.php?t=442221

Cheers
