Hey it looks like updating to Mint 22 fixed my weird WiFi issue I was having.
Like IDK if this was a problem with Mint 21.3 or with my modem/router, but we recently got a new modem/router from Spectrum because last month, our Internet just completely went out and nothing we would do could fix it, so Spectrum came out, did some checking, and replaced our old equipment.
It was all working fine and dandy but then one day, the Internet went off and back on in like 15 seconds and, after that, the Internet on my laptop when connecting via WiFi became crazy slow, functionally unusable even.
Before I would get - depending on how many other people were online, remember there's four other people living here - download speeds of like 180 to 300 Mbps and upload speeds of like 20 to 30 Mbps. But after that, while the upload speeds remained unchanged, I would be getting like maybe 4 Mbps down AT MOST and it would often just drop to sub 1 Mbps.
And it was only my laptop that was having this issue, no one else was complaining about slow internet speeds, the streaming on both of my TVs was still fine, my Switch was connecting fine, my phone, and my tablet too.
Literally the only thing I could do that would actually make using the internet usable again on my laptop was just...connecting my phone to WiFi, plugging my phone into my laptop, and sharing its internet connection. Nothing else worked.
But now that I've upgraded to Mint 22 and I'm not facing those issues at all anymore.
So yay?
