Thread: Cannot find Wireless networks

Hi, i just bought an HTC TOUCH HD, i do detect W-lan when i'm about a 20 in from a router. if i go out of the room i lost connection inmediatly. in my bedroom with my laptop i find about 6 networks but in my htc i cannot find any. i have switched my settings to best performance and it still doesn't get any signal. at the mall i don't any network either.
i would like to know what's the problem is the router or mi device. how far from the routher do you guys get connected?
thanks for your time and answers i hope you can help me out.
