The Hama stick comes with the job have no problem.
The installation was quick and straightforward:
Stick in a free USB port (2.0), install the configuration software from the CD, select an existing WLAN from the list of found networks, "Create Profile" button, enter login information and then "activate profile" in the Profile tab - done.
The signal strength is excellent, ergo a very good reception and transmission performance.
If you - like me - already had a wireless card, you should disable the item in Control Panel because the parts otherwise get in the way (so my experience).
The Hama stick is stable in continuous operation, it is a bit warm, but not overly so, and affect the quality I can not find.
When changing to another account on the computer (if necessary. Must be the aforementioned means for each account once make) the power for a few seconds is gone (is probably because, like Windows USB interfaces handle the account change), but that is in usually not a big deal.
For the price a No-Brainer (in German: since you need not think twice before buying), clear recommendation!
