Kubuntu 22.04 Wi-Fi issue.

I’ve installed Kubuntu 22.04. It’s got Wi-Fi issues. Freezing and dropping on occasion. Then wide open. I’ve been reading where it’s a known issue.
My question, is this unique the Kubuntu? I’m thinking Ubuntu 22.04 would have the same issue. Is there a fix coming /known?
Thanks.

Please specify which NIC you have. You can also boot up 20.04 or 21.10 and check if the problems also occur there.

You are right. The NIC / driver is Atheros AR9485.

I was running Kubuntu 19.10 and things work great, including the internet. But as the support ran out, I was forced to move on. I chose Ubuntu 20.04 with KDE installed. Worked fine. I ended up trying Kubuntu 22.04 whe I realized it was out. That's when the internet started acting squirrelly. I've got Slackware 15.0 installed at the moment and the internet is working fine.

I have an old machine, HP Pavilion G series. I would stay with Slackware as I've ran Slackware for years. But I have some older software that I enjoy running and the 15.0 version has some difficulties running them. (It's probably operator error)

In any case I wanted to try Kubuntu 22.04 but can't get the internet to stay running long enough to download updates or application packs. I looked it up online, thinking maybe the latest Kubuntu was just advanced for my old machine. However I came across several complaints and people smarted than me seem to think it was an issue with the new kernel. If it was kernel / software related, I was thinking someone might have updated it to correct the issue.

Thanks

Doesn't the old machine have a common ethernet port? For the first updates you could just use the hardwire connection and get it all updated and then test your wifi connection. Also, if wifi connects/disconnects sometimes getting close to the wifi router will stop that too. Just a thought.
