I'm "trying" kubuntu 22.04.1 from a dvd. That is I haven't actually installed it. It seems to be running OK but I can't connect to internet via wireless wifi. I'm lost on how to set up the connection. Documentation points me to things that don't seem to exist.

  • what does the documentation point you to that doesn't seem to exist? – Esther Dec 13 '22 at 00:59
  • I would write the 22.04.1 ISO to thumb-drive and "try* Kubuntu from there if you can. Ubuntu no longer aims for optical media installations, and you can experience timeouts due to extra time caused by your use of DVD (or optical) media that can cause your system to experience errors you won't have post-install. That may not be your issue, but unless you've checked your system logs it may also be. Normal wifi troubleshooting details can be found here where 3. Device Recognition and Operation will most useful. – guiverc Dec 13 '22 at 01:51
  • Do note: the link I provided assumes Ubuntu Desktop (not Kubuntu), but the same applies to all flavors of Ubuntu (ie. to Kubuntu) as we all use the same underneath Ubuntu infrastructure. – guiverc Dec 13 '22 at 01:52
  • Ester - https://help.ubuntu.com/stable/ubuntu-help/net-wireless-connect.html.en System menu wasn't where it said it was. The menu I found didn't name any networks. – Bugdog Dec 14 '22 at 23:08
  • guiverc_- Yeah, I was thinking the same thing. Running an OS from anything other than a hard disk is something I'm still on a learning curve with. – Bugdog Dec 14 '22 at 23:13
  • I run live systems (including with persistence on occasion) from thumb-drives very regularly without issue, but I'd not use a DVD unless it was purely for QA (Quality Assurance) purposes, the last time being to confirm the issues with DVD post-groovy (20.10) changes & to ensure install was still possible. Adding kernel modules (aka drivers) to a live system (regardless of media) is always harder, so live or not-installed is easiest with generic hardware with mainstream (enterprise) hardware (less so consumer grade unless very common). – guiverc Dec 14 '22 at 23:20
  • I found the troubleshoot page on my own. (thanks anyway) . I didn't get a connected response. I did find that the machine knows it has a card (PCIE). I got indications it has a driver. I suspect though it's not working because it's a windows driver. I haven't yet figured out how to install a driver to test that. While trying to set up a wireless connection I had blank fields that I didn't know how to fill. SSID and such. – Bugdog Dec 14 '22 at 23:24
  • Drivers are actually kernel modules; thus are built for specific kernels (why a windows 7 driver may not work on 8 or 10 etc), so you need a kernel module (aka driver) for the 5.15 kernel used by Kubuntu 22.04 LTS. If talking about a printer driver, as many are just text files they will work on any OS/system (macOS, Ubuntu or windows), but hardware drivers are built for a specific kernel. Drivers are made for the chipset on the hardware they control; 3.1 on https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide is where I'd start (for Ubuntu & all flavors inc. Kubuntu) – guiverc Dec 14 '22 at 23:37
  • Hey, the thumb drive worked for what ever reason. Boot from that and a wifi icon shows up at the bottom right. Put in a password and all is right with the world. Thanks all. – Bugdog Dec 16 '22 at 01:41

I suggested (in comment) I would write the 22.04.1 ISO to thumb-drive and "Try" Kubuntu from there if you can. Ubuntu no longer aims for optical media installations, and you can experience timeouts due to extra time caused by your use of DVD (or optical) media that can cause your system to experience errors you won't have post-install.

These issues are seen in logs, so you need to explore system logs at terminal to recognize/confirm this. You can re-try the boot & install & next time it may work (it works flawlessly about 33% of the time in my own [rather limited] QA) with it failing if timeout is reached before data is read. The GUI messages post-timeout are not helpful though & only make sense if the full system logs are read and you recognize the subsequent error was because of optical-read timeout.

The OP confirmed it was (as I read it) related to the optical installation media which is not intended for releases past Ubuntu 20.04 LTS. This answer just to close the question.

  • this answer is just copy/pasted from my prior comments, with some edits & expansion; alas mostly my opinion as result of QA. The 33% may vary on hardware, both CPU & optical drive & my testing was limited to only a few dell & hp devices, none of which are newish. – guiverc Dec 16 '22 at 02:00
