My WiFi worked fine until around a week ago. It now drops off after a few minutes and then comes back on again after a while which could be anything from 5 minutes to 20 minutes. I have dual boot (unfortunately need windows for some cad package!). The WiFi works fine on windows so I know its not the adapter. I tried just about all the suggestions which I could find. Kernel is 6.5.0-35-generic. Dell Vostro Laptop. I am currently using a 6m long network cable to access the internet. Not very convenient!
If you go into windows and check the network wifi adaptor, collect make model and any other info under properties from right clicking on the adaptor in windows.
Then go back into linux
Check
Software & Updates → Additional Drivers.
See if it offers anything in the wifi driver area matching your info collected under windows
If not please reply with the information so someone on this site can advise you
Linux does come with most installed but occasionally it needs some help
Hi. Thanks for the quick response. I haven’t made any changes to the power settings. I double checked that. I disabled IPV6 as recommended as one of the solutions. I also changed the power setting to 2 as recommended as well. Both these haven’t changed anything. It seems to be a common problem which Ubuntu 22.04 users are experiencing.
I’d look for a kernel update around the date you first discovered the problem.
I assume you use Ubuntu, or something derivative.
Just boot up your system with the previous kernel, and see, if the problem does vanish?
You can find many sources on how to boot a different installed kernel, for example:
Cannon Point-LP CNVi [Wireless-AC] does appear to cause many others problems with drop our but the suggestions you have already implimented in kernel upgrades.
As wifi keys are so cheap I would be tempted to buy another and try that.
Thank you very much. Are you referring to a USB WiFi key? If so I’ll get one of those and try it out. That’s what I have on my desktop also running Ubuntu 22.04 with no issues.
That model cannon had issues with older versions of ubuntu 20.? But either went away by 22.? Or other users were then on other connection systems.
Most of my research was based in france where it was a standard on some machines for a period. Hence the ubuntu forums had many examples but mainly suggestion the update fixed it.
Yes, as I mentioned earlier the WiFi worked fine for the last 6 months or so and started giving me problems in the last week. I can do one of 2 things, either get a USB key or change the WiFi card in my laptop. Its a Dell Vostro 5581. Will have to find a card that’s Linux friendly! Will probably give the USB key a shot first.
That may suggest a recient update to your system could be the cause.
Wifi cards are also cheap but more than the usb keys.
Try the key first but you may have to physically remove the card at some stage.
I would be drawn by tp link as my prefered out of the box solution.
One issue you may face however is position, if your desktop machine is in efect under a table the range or view of the router could be a problem without antennas and repositioning may help.
Run this grep, it will theoretically show a list about what packages were upgraded and when.
Copy it here.
In your situation relevant finding will be the kernel packages, an firmware related packages I think.

So you have a HWE kernel too. Did you install this intentionally, or Ubuntu installs this by default?
(I’m not an Ubuntu user, hence I’m not sure).
I’d try to boot the 6.5.0-28 kernel, for that you need to reach the GRUB menu like you did before.
After boot up, make sure the system runs on that kernel, run this command: uname -a
It should output a string somewhere mentioning 6.5.0-28 (your actual kernel version).
Does it?
Well, if yes, your system really runs on a previous kernel.
Use it for a while to see, how the wifi behaves?
Hi and thanks for your assistance. I did not install the HWE kernel intentionally. Ubuntu must have installed this by default. I am booting from 6.5.0-28. I went back from the newer 6.5.0-35 kernel as suggested. None of this has helped. Currently I am using a USB TP Link WiFi key which I bought today. It is the TL-WN725N and is working flawlessly so far.
