I will say that some distros "find" & connect to wireless easier than others. It all depends on the wireless adapter inside the machine.

The easy go to distro for wifi is Ubuntu, it has always found & connected wifi for me and I have tried out at least 15 of the various top distros.
If you don't care for the ubuntu default look you can click to use the old style classic or use the repositories to get XfCE or other "styles"

Xubuntu is based off Ubuntu so wifi worked connected nicely on Dell laptop.


I use ISO burner, very easy.

be sure to set burn speed as slow as you can for best results. I did some on automatic/default speed and they did not work.
