Another thing to note was that Sky originally blamed the fault on a McAfee update. I looked into this and deinstalled McAfee and even spoke to them for a while and they confirmed that it had deinstalled and did some other tests and said it was definitely not their software causing the problem.

have you removed the mcafee completely
I would suggest that
we have a link to how where
http://forums.techguy.org/networking...s-network.html
next this may not work (as wireless often does not work in this mode) , but its simple to do - so please try anyway
- try safemode with networking
as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works
------------------------------------------------------------------------
next can we see an ipconfig /all and an xirrus screen shot
------------------------------------------------------------------------ ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.
We would like to see the results from an
ipconfig /all - post back the results in a reply here.
Hold the
Windows key and press
R, then type
CMD then press
Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):
In the command prompt window that opens, type the following command:
Note that there is a space before the /ALL, but there is NOT a space after the / in the following command. ipconfig /all > network.txt & network.txt
It will export the results into notepad and then automatically open the notepad and display on your screen.
Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose
Edit -
Select all
all the text will now be highlighted
Next
From the notepad menu - choose
Edit -
Copy
Now go back to the forum - goto the reply and then right click in the reply box and
paste the results.
The results from the notepad should now appear in the forum reply.

Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
note: the signal level is a negative number, so for example -88 is worst and -40 is better
If you are using the Mac OS then use
http://www.istumbler.net/ or
if you want to optimise base station position and signal strength / dead spots use
http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal
