Great Gergät with great WiFi weakness

After 7 days I returned the tablet again.
Actually, I found that the tablet well was in the hands and the display was readable in each charge. Even if it was in the envelope of "Supremery" I could work well with it. Only I always had to be near wireless router (max 3m with view of the antenna). Am everywhere walking around with it in the house, with an ASUS EeePC 10Zoll and 'nem Lumia820 in tow. In the living room (approx 8 summarizes and visual contact with the router) on the couch with the Odys no wireless, but 80% of the ASUS and 100% with the Lumia. In the living room (my parents) in the basement, where the Odys should stop most, I had with the ASUS still 50% WiFi signal and 60% with the Lumia, but no reception with the Odys.
Thus the fate of returning for the Odys was sealed, because what I do with 'nem tablet without secure connection to the network. And the day just near the router, I also did not want to spend.
Therefore, only one star, if ever ... :-(
