What is worrying to me, are the many dropped packets that went through your wifi.
Are you sure you are using the right driver for your wifi chipset ?
Or did you setup a firewall on your router’s firmware?

Happy new year,

On a second thought, open a terminal window while connected to wifi and please post the output of

resolvectl

Cheers,

Well, Everything works fine in Win10 (dual boot). It was only when I upgraded from Mint 21.1 to 21.2 that I had all this trouble. I'll have to get back to you about the resolvect1 results as that machine is off right now. No firewall on the router.

What is the output of ...

nmcli con show

One of the devices listed here, should be your wifi interface.
run the same command, with the name of the interface at the end.

nmcli con show wno22 ( yours probably won't be wno22 )

Your DNS servers above, "could" be right.
It looks like it's trying to use dynamic DNS through the DHCP from your wifi router.
Your DNS Domain, usually isn't a number, it's a string like "spectrum.net" or "comcast.com", or something similar.

Is your wifi router from an ISP, or is it your own personal router?

to edit your ip information you need to go to the setting for the network device. This varies from flavor of linux to flavor. You will want to go into those setting and find the IPv4 settings. I am convinced you have bad information in there. I am not sure what "dns domain" is as I normally do not see it. DNS should always show up here as an IP address not a name.

If you're able to plug in an ethernet cable and it works but then wifi does not, you need to go into the wifi setting and make sure the IPv4 is all set to automatic or obtain from DHCP. That is the default and should work in 99.5% of cases.

What I see in your information says that you have good dns server information but DNS domain is something a bit unfamiliar to me. I doubt it should be set to google server though. Wipe it out if you can or set it to automatic. Wiping it out means wipe it out do not set it to 0.0.0.0 that will not wipe it out. So set to all zero only if no other choice to wipe it out. blank is best. Also make sure the gateway address is your IP address with a 1 replacing the last set of numbers. All this should be done if you set to auto or DHCP. You can check your wired adapter setting while plugged in and match the setting on your wifi adapter.
