Re: 2.4 GHz Reception Indoors?



1.  At microwaves, water in vegetation is an absolute killer.  You'll
do better through it in the winter...

and

2.  I have an "English Basement"-- sorry I didn't mention it, but half of my 
basement wall in the back of my house (South) is OSB, wood, fiberglass 
insulation and vinyl siding!
