So, I received an email from one of our members asking how to go about installing the drivers for an edimax EW-7128G PCI card on Hardy Heron (7.10). I won't post the contents of the message here to respect their privacy, but it seems like the computer in question has no other method of accessing the internet (always makes it hard, doesn't it?). A net connection is available on another computer, however, and they can transfer files between the two on CD.
Now, it's been a while since I've used that card, since my computer's now next to my router and thus connected via wire, but I'll see what I can remember.
This card uses the rt2500 chipset, which should be supported automatically in Gutsy and later. All you should need is the rt2500 packages, which you should be able to get off of http://packages.ubuntu.com (it's down atm, so I can't check).
However, if it doesn't, there are a few places to look. One is the entry on the wiki, which also provides a few links at the top. There are some instructions on how to use the Windows drivers through ndiswrapper here on the forums (though that's not the first option I'd try), and also some notes at the bottom (very bottom, it's quite long) of this bug page on how to compile the newest testing version from source.
Those last options are quite a bit of a challenge for someone who's new, so I'd first try just plugging it in and seeing if it works. I'd check and see if it shows up in the network admin, and if not, start going down this list of commands. Specifically, post the output of lshw and lspci. The terminal can be found in the menu at Applications menu -> Accessories -> Terminal, then just type these two commands:
The > indicates that the output will put to a file called lshw.txt and lspci.txt, respectively. You can then go ahead and open those files up and copy+paste them in here.
lshw > lshw.txt
lspci > lspci.txt
