To date, the Linksys WUSB600N was my favorite, although he mucked 7 under Windows. Whether 32 or 64 bit system, after cold or warm start there was always an abortion and you had to remove the stick, and reinsert it. Annoying, but it was just the strongest of my subjects and brought four bars in the display and my full bandwidth, which no one else managed.
The Digitus but came a new wireless feeling for me:
Quickly installed with the enclosed CD. Immediately, I saw 5 bar in the Windows 7 display. That was hope. Finally is my Netgear router in another floor, separated by a thick reinforced concrete ceiling.
And the tests did not disappoint me. My 64 Mbit line goes through 100%. When I would be connected to the network cable. Great!
The functionality is uninterrupted. After two days of continuous test, not a misfire, no Macke!
Conclusion: The perfect wireless stick - super fast, very stable, and all for a bargain price. Recommendation: Buy, buy, buy!
