WiFi DWL-520 ISL3874 [Prism 2.5]/ISL3872 [Prism 3] (rev 01) uses hostap
I would have thought that this Prism chip would just work, but not the case in Slackware 14.0 [and earlier versions as well] (The biggest problem was figuring out what module needed to be loaded and I had no clue, I searched for ever before I found out it was hostap.) (In this case it's a PCI card in a desktop PC.)
I found that /lib/modprobe.d/hostap.conf was blocking the module "hostap". I simply had to comment out blacklist hostap_pci and blacklist hostap lines to make it work, like so:
In Slackware 13.1 and 13.37 I also see lines in /etc/modprobe.d/blacklist.conf
And so we'd need to comment out hostap and hostap_pci lines in order to make this card work.
