Discussion of behaviour on arch forum: - notice 'Last night's push of 5.17.1-arch1-1 clearly fixed all the problems I was having with my Qualcomm Atheros AR93xx Wireless card'.

The kernel bug 'ath9k frequent connection problems after kernel upgrade': - notice 'The same change that affects 5.16.15 was also incorporated into the 5.15 tree: 5.15.28 works, whereas 5.15.29 and 5.15.30 don't.'.

For the first fixed version uname -r reports 5.15.0-33-generic Links

Tp link wdn4800 driver software update#

Now on 20 May an update to 5.15.0.33 was offered and it definitely fixes the wifi problems I was having.Ībove version numbers are those reported by 'Software Updater'.

On 13 May, the update to 5.15.0.30.33 also had broken wifi. Using ubuntu's kernel version numbers, the original was 5.15.0.25.27 with broken wifi. I'll try 22.04 again after the next kernel update - if you're still interested, let me know and I'll let you know the results. Since it took me a while to track down, I thought I'd share. I know wifi issues can have many causes, and my answer is not perfect - particularly since I haven't reinstalled ubuntu 22.04 and installed a different kernel to verify the fix, but this setup has been rock-solid over many operating systems over the past few years, and this was the first time I've seen behaviour exactly as you did. The smoking gun here - in my view - is the exact same BAD WIFI behaviour newly occurring over two linux distributions where pretty much the only thing they had in common was kernel version. I then saw exactly the same wifi behaviour when using the 5.15 kernel in manjaro. This was with a 'TP-LINK TL-WDN4800 N900' PCI-e wireless card, with Qualcomm Atheros driver. I was dual-booting with an existing Ubuntu 21.10 installation which continued to show no similar problems, so I knew that the problem was specific to the updated OS. I had exactly the same issue with 22.04 - everything else fine, but I had slow wifi that would regularly silently disconnect. The fix is already available in the kernel sources for 5.15, but downgrading until it is available in the ubuntu 5.15 packages is a reasonable workaround.īased on dates and schedule only (the upstream fix was committed 28-Mar, after the previous ubuntu kernel commit deadline but before the start of current cycle), I am hopeful that the next scheduled Ubuntu kernel release on 09-May will fix your problem. If so you can only fix the problem today by changing to another kernel version without that bug (this can be done without changing anything else). I think it is likely that you are hitting a bug with the 5.15 kernel (linked below) that is used by Ubuntu 22.04. Original answer follows, then detail of which version fixed it for me.

UPDATE: latest version of ubuntu 22.04 does not have this problem, just install updates. Can I use the part of the system that handles the networking stuff from previous version of the distro?) Should I just downgrade the entire OS? Or is there a way to fix this? (e.g.

It turns off intermittently, doesn't let me download large files, streaming is also difficult. The overall experience of ubuntu is better, but, the wifi is having issue.

Which should mean my drivers are installed, right?

I just installed ubuntu 22.04LTS since it has been release, and right off the bat, I notice my Wifi is extremely slow, it only downloads at 500Kbps, and I tried to download pycharm ~500mbs, it fails each time.
