For my M-Tablet and travel I bought the wireless kit, to use the tablet with my MacBook.
Initially I had huge problems with the radio connection. The line went dead, either completely or from the history of the mouse was so hakelig that you could not work with it. As long as the tablet was connected via USB cable, everything went smoothly. Eben just the wireless connection did not work clean. I have all the drivers installed and otherwise tried everything. No Result Found. I had really been fed up and wanted the kit actually return.
Now I have found the solution and all is well:
The dongle that plugs directly in the MacBook is seemingly so greatly disturbed by the laptop, that the radio connection is broken or hooked. Now I have the dongle extent removed by a short USB extension cable (only about 6-8cm) from your laptop, that it can build and maintain a smooth wireless connection. Since I started using the extension cable, the tablet with the kit also works great in wireless mode.
Since - as far as I could see in internet forums - there is a problem that some users of the wireless kit, I hope that this post, one or the other, will help.
