I share my internet with other gadgets via an ad hoc WiFi network via my laptop running Windows 7 Home premium. The range covered is extremely bad. At as less as 10 meters away, in an open hall, from the laptop sitting on my home office desk the signal is weak - it shifts between zero and one "curve" on network notification icon on my gadgets.The signal is non existent in the floor immediately below. (The floor is made of reinforced concrete.)
What can I do to get good reception?
Thanks.
