With careful antenna placement and use of 'iwconfig wlan0 rate 2M' I
have a nice reliable connection. Thanks for the advice on lowering
the rate.
Does anyone think I would be better off with a 15 foot antenna
extension cable and a PCI adapter than what I have now which is a USB
adapter on the end of a 15 foot USB cable? I know antenna cables are
lossy.
