Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

This is for my desktop which has no built-in wifi adapter. I am currently using a ZyXel dongle which works fine using the zd1211-firmware package. The problem is it does not support 802.11n. It only has 802.11b/g support and this results in a 33% loss in connection speed.
I made the mistake of ordering a SAVFY dongle from Amazon but can't get it to work. I should have read the reviews before ordering it. They all say it is a piece of junk. In any event it cost £5.95 which I have written off.
Can anyone recommend a dongle supporting 802.11n which actually does work with linux and is easy to install or at least has clear instructions. I found this one: IOGEAR Compact Wireless-N USB Adapter GWU625 (Black), also on Amazon but would appreciate your personal recommendations for one that is known to play nicely with linux.
Thanks for that, aus9. I must be blind or senile but I can't find the brand name (to find a closer supplier than Australia). Yes, I have the firmware-realtek package in my repos. Do you happen to know the brand name of this product?
Update: I looked for it under "Realtek" and found it on Amazon.co.uk and have now ordered it. If I understand correctly I install the firmware-realtek package, shut down the machine, plug in the dongle and restart and the system should find the realtek wifi adapter. Is that correct?

If it's a desktop, wouldn't it be better to use an internal WiFi card?
Why? My ZyXel dongle works perfectly well and has done so for a number of years. It still works now but it doesn't support 802.11n so I don't get all the speed my wifi connection is capable of. That's why I'm looking for another dongle.
Thanks Brian. Too late though. I've already ordered the Realtek one suggested by Aus9. I'll wait till I've received the Realtek and successfully installed it before marking this thread as solved. Thanks again to all who answered.
Thanks again, Aus9. I think you misunderstood. I have been using a dongle for several years and have no problem connecting to my router with my ZyXel dongle with zd1211-firmware. I prefer to use wicd-curses for my configuration but I think that amounts to the same thing. I do have both rtlwifi and RTL8192SU folders in my /lib/firmware folder (along with the zd1211 folder which I used for my ZyXel dongle). The problem was that ZyXel doesn't support 802.11n (only 802.11b/g) which is the reason I was looking for a newer dongle.
So the dongle works with the ZyXEL driver zd1211rw. But I can't find the RTL8192SU driver. I have installed the firmware-realtek package but lsmod shows no sign of any module being installed. Since zd1211rw doesn't support 802.11n there's no point in changing from my old ZyXEL dongle. Can you tell me what the driver file is and how I install it. I seem to missing a step here after I install the firmware-realtek package.
Ok, now the dongle works and I get speeds up to 37+ Mbs whereas I could only manage around 21Mbs on my old 802.11b/g dongle. I did need to manually insmod the r8172u module. But here's the weird thing: when I boot up with the RT dongle plugged in there is no sign of life; no blue light flashes. No reaction at all. To get the wifi working I have to boot up with the old dongle. Once the system is running I then unplug the old dongle and put in the new dongle. The new dongle then responds and performs normally. The substitution changes my ip address (within the local network) and my hostname gets lost and is replaced by "unknown-<mac address>" No amount of fiddling with the hosts, hostname or dhclient files change this behaviour. Any suggestions about these two anomalies would be most welcome.
