Comment 6 for bug 508746

I also have a Samsung R580.
With the Lucid Kubuntu Alpha 3 Live CD, the r8192_pci kernel module is loaded but the lshw tool reports the HW as "disabled". I downloaded the firmware as explained in #2, then I rmmod-ed and modprobe-d the module again. After that the WiFi was up and usable.

To answer #5, I DL the source of the linux-firmware 1.32 and compared with what I DL from git, and it is completely different (names & sizes). So I think this won't solve the problem.
Git := boot.img data.img main.img
Src := rtl8192sfw492.bin rtl8192sfw74.bin rtl8192sfw.bin
