I'm planning to buy a WLAN USB Adapter one of the following days:
I got the choice between the WUSB54GC en the WN821.
From the Linksys, I am certain that it is fully supported by BT4 R2. Nevertheless, it's a quite old device with only 54 mBps. The WN821 support 300 mbps and has a bigger range. But I'm not entirely sure if it's supported since I find all kinds of information(reports that it works easily and other that it doesn't work) They both cost 20 Euro. What do you guys think is the best choice? How are your experiences with these devices?

Thank you in advance
