The reason I want to install an old kernel is that my laptop WiFi adapter doesn't work well in monitor mode. By that I mean, airodump shows all clients as "not associated" when they actually are.

In the past, I managed to fix that by installing the kernel image 4.0.0-kali-686 pae, which worked well with the wifi driver (b43) for my wifi adapter (BCM4311), but it's been over 3 years now since I last used Linux and I don't remember how to do this.

The "not associated clients" problem has to do with either the wifi driver or with the kernel, but I don't know which one is to blame. I installed the latest version of Kali Linux earlier today and just updated and upgraded it. If it helps, the "not associated" problem was encountered before and after the upgrade.

    Probably not doable. Stock kernel in Kali 2022.4 (in Kali now) is 5.16.0. Try this article for recompiling the Kali kernel. .... kali.org/docs/development/recompiling-the-kali-linux-kernel Can you (better) upgrade the Wireless Adapter.

  • I managed to do it in the past in Kali Linux 2019 which by default came with a kernel version higher than 4.0.0. I did a lot of research back then and eventually installed the kernel version 4.0.0 alongside the stock version. Everytime I wanted to work with monitor mode enabled, I loaded the older version from Grub. It worked back then and should work now. @John

  • Try the article. V2022.4 is a long way ahead of V2019 so I have my doubts.
