Wireless connection

I'm really baffled now.

Before my wireless adapter thing was hanging over a door on a special extending USB cable - not an ordinary USB cable. I was getting a signal strength of Low Speed 24.0Mbps.

I then moved it - to a position where there was a direct line of sight between it and the wireless access point. Now I'm getting a signal strength of Very Low and a speed of 1.0Mbps.

I just don't know what to make of it.

Peacock dreams.

Edit : It's now at 12.0Mbps although it did go to 54.0Mbps. What the hell can be affectinh it when there is a direct line of sight.
