Mac OS X: MacBook Wireless

The MacBook Pro’s wireless reception is relatively poor in comparison to the MacBook. The reason? The aluminum casehas a tendency to interfere with its radio waves. The wireless signal is received only through the antenna located in the clutch (note the rubbery area under the MacBook Pro lettering on the bottom of your display) – that rubbery material is transparent to the radio waves.  The MacBook itself has a plastic case.  Most plastics, unlike aluminum, are relatively transparent to radio waves – so better wireless reception.
