decent netbook with low WLAN performance

for the price a decent netbook, ultra-light, clear colors. The only shortcoming is, and therefore a trigger, the wireless power does not reach a 15 inch model of the same brand. From the basement through the concrete ceiling, the performance of the Extensa 5630Z is quite enough, moment during this netbook suuuucht, and suuuucht, and did not find anything.
