The first I have returned as defective because it did not work under Windows 7.
I had, like, first install the appropriate Dremel Software in the accompanying description and then connected the stick. But repeatedly reported the computer, which is connected to the WLAN stick NOT.
As I said, I took him for defect and gave it back.
When the second attempt the same thing happened, I was taken aback. Twice a defective device? That can not be.
In telecom forum, I found the solution. The included software is only for Windows XP and Vista.
In Windows7, you can dispose of the attached Speedport software CD or can be safely in the pack because Windows the key installed automatically. But only if you let off the Speedport software.
Conclusion: This thing is going great and I am very satisfied. 4 stars there because of the lack of reference to the function with Windows7.
So I had Amazon and even saved me returning and me a lot of time with installationsveruchen and root cause analysis.
If you know that: buy!
