"I started receiving timeouts when the distance was about 30 yards and while
I thought this to be a little shy of the claimed 50-100m, the 30 yards
wasn't in a straight line in complete open space. Basically, it wasn't

The documentation of the DWL-650 states that walls will decrease distance by
anywhere from 1m to 30m per wall. Within those 30 yards, I was able to
wander from desk to desk in the office and never lose network connection at
