BBDom,
Have read people using the drivers from the website you mentioned above has given some good results.
I have made some notes, as they become available for Recommended Wireless Router Settings WPS can be an issue with some adapters and the note below about Coexistance may also help. I do not use the firewall in my wireless router. The computers all have firewalls, especially if you take them to a public WiFi, you should be protected.
