looking on website i found instructions to use command tar zxvf zd1211lnxdrv_2_21_0_0.tar.gz but this didn't work either, it said there was no such file or directory.
Well, that says it - there (the place that you were currently working in, probably your home directory unless you changed it) is no such file that you tried to extract. The right way is to pop up a terminal, use 'cd' command to enter the directory (on the cd?) where the package is, and then issue the command.
..or, because this is Fedora, put the cd in (a file manager, Nautilus probably, should open - if not, open the CD by double-clicking on it's icon so you can see the contents), locate the zd1211lnxdrv_2_21_0_0.tar.gz package, copy it (right-click on it with your mouse, select Copy), head back to your home directory with the file manager and select Paste from the menus, or right-click the background with your mouse and select Paste. Now you should have the package there (or you could just drag it to your home directory from the cd, if you had two file manager windows open). Then right-click on it and select the option to extract it ("extract here" if you like, maybe make a new directory, put the archive there and then extract it to get less mess), and there you should have it's contents - just what tar -zxvf would do (zxvf = eXtract a gZip compressed archive, Verbose output, File <filename>). Then look inside, and try to find further instructions - maybe a README file.
On the other hand, if the light blinked on, it may be it works already. Often if there are no drivers for a wireless device, it won't power up - when it does, it will. There is a chance it doesn't work though there is a light, but you can always try. So before extracting the archive, test it - either use the NetworkManager applet you can add to your panel, or open a terminal and
<type root password to become root>
iwlist eth1 scan
If the latter command says "eth1 doesn't support scanning", try wlan0 instead of eth1. The name varies so you may need to try both. If both say "doesn't support scanning", it means that the driver isn't working. If you instead get "no such device" or similar, it could mean the device is not up; try running (as root again)
and then the scan command again, or the same for wlan0 if you didn't get results. If the device works, you should get a list of wireless access points found in the area - this is a good sign, and next you can move on to graphical apps to connect. But if you don't get such a list, there is very probably still something wrong with the driver.
The CD should contain straightforward directions to get the drivers installed, usually a README or INSTALL file or both. Might be inside the package like I mentioned..anyway, even though there are probably commands mentioned that you need to run to get it working, you must of course run them in the directory where the needed files are. When using command line, you can see your current ("parent") working directory with
That should be the directory where the files are that you're working with. If it's not,
and your working directory is changed to /path/to/new/directory. Use
to list files inside the directory you're currently working on, to make sure it's the right one, and remember that in Linux a difference is made between uppercase and lowercase letters, unlike in Windows (so: 'Hello' is not the same as 'hellO' which is not the same as 'heLLo' and so on).
