you could try to uninstall the utility to see if it will work stably.
You can also try this way to connect the wireless network:

Hi
Thanks for reply.
Uninstalled new version of utility and re-installed original version from mini CD supplied.
Same problem.
Its as if the power management is switching it off despite having switched this option off.

I had a similar problem I think with the TP-LINK USB wireless adaptor. I lost the wireless network connected icon from the system tray after tinkering with a Kellys Korner macro and could not find how to get it back.

So, I decided to use the TP-link adaptor.
It connected fine bystarting the config utility, clicking on the 'Network' icon and the wireless router in the list of available signals, clicking on connect and entering the password. All fine. But the pasword seemed to vanish every time I switched off, and in my case it was selecting another server by default (A neighbour's?) and this would not connect.

So clicking around aimlessly I clicked 'QSS' (no idea what this may mean), 'auto' and hit the 'QSS button'. The 'progress' bar grew slightly then stopped. I then (Don't know why, so don't ask) Then going back to 'Network' there was a little twirly spinning pair of arrows next to the router name where it appeared in the list. 'Oooh'....I said, looks promising I thought. Switched off, switched on and the password had gone.

So.

I clicked on 'Profile' (Don't now why I did this either) and added a profile called 'Prof 1' with my router picked from the list. It had a blue triangle next to the 'Prof 1' profile and anothe blue triangle next to the router icon.

I restarted the computer....Bingo! success, auto connect with the password retained, Wi-Fi joy unbounded.


All is not yet right there is a funny script appears on restart but I just click on its X to turn it off.

Mysterious.
