hi all,


i have a asus 1001 pxd netbook(intel atom 1,6 ghz,1gb ram,windows 7,intel graphics accelerator 3150),with a wifi network adapter "atheros ar9285".my problem is:when i sit in the kitchen with my netbook (about 6 meters away from my wireless router, a belkin with model number f7d1301 v1,and just a single wall between my netbook and the router)i have 4 or 5 ( max is 5) connection signal with my router(internet with no problems).but when i sit in my bedroom with my netbook(about 13 meters away from the router and 2 walls between my netbook and the belkin router and 1 floor higher then the router),then i have only 1 or 2 connection signal (max is 5)with the router(sometimes the netbook can not even find a router at all in my bedroom,WITH IS A VERY BIG PROBLEM.) we have a cable networkprovider,but connection between pc's of this house and router of this house is via wifi,if this info helps.also we use a wpa2 key.once connected to the belkin router on a signal higher than 3 there are no problems at all,perfect internet and downloads.
