I have a belkin n1 wireless router with 3 external antenna. This is a good router but it only make it a few rooms out because it is in the corner of our basement and i can't move it. Is there any antenna adapter for belkin router or an after market one i could buy. i9 nee this to get to the third story of my house with great signal strength. Are the any wireless-n receiver for a G4? or any extenders.
