The range is comparable to the other wireless devices that I have or had. No more and no less
To speed was in the previous reviews already said a lot. The drive synchronizes with the full 150 Mbit (more does not support the router) and irritates my 16Mbit Internet connection fully. The speed on the local network, unfortunately I could not test in detail.
Especially important: The connection was stable for several weeks continuous use.
The big BUT: Windows 7 64-bit does not included drivers, the CD is therefore required. However, it is not normal sized CD, but a "mini-CD" with a smaller diameter. In normal CD / DVD drive is in the middle of the tray for an extra recess. "Slot-in" drives, in which you simply reinschiebt the CD in a slot, but can not tolerate this small CDs! Who has such a drive should definitely make sure that it can transmit the drive from another computer with "real" drive to the target computer, such as a USB stick.
Knowing this, then that is no reason, however, devalue the otherwise very good product, so 5 stars.
