I have been using 3Com usb adapter(3CRUSB10075), with a Zydas ZD1211 driver... and it was working almost perfectly... but then I found out that it was killing the fan control on my machine(Acer Aspire 5104wlmi hackbook), everytime I went online.
As overheating was my nr.1 problem, I have now stopped using it(and the overheating problem is no longer a problem)
But perhaps that is just a problem on my laptop...

So now I am looking for another solution. Perhaps a cardbus wifi, or a USB solution which uses a better driver.

So, I would love to hear what you guys here are using...
