Hello, I have recently installed pclinusos2011(kde) on and old laptop of mine (Compaq Evo n620c) and every thing was working great, it detected my wireless card and seamlessly got me on the internet. Yesterday I decided to update my system with Synaptic and after the update finished I rebooted and attempted to get on the internet but got an error stating ''the following component is missing /lib/firmware/isl3886pci" which relates to my wireless card, the error also gave me a download link to the missing file
which I have downloaded but I do not know what to do with it,where to put it or how to install it.The download link offered some install help but this was way over my head. My wireless card does show up in the network center but no network is listed.. Assuming this is my problem could someone offer me some simple advice on how to get this working, Thanks in advance for any help given.
