I'm paraphrasing here, but the general tone of the FCC rules for  
operating in the 2.4Ghz. band are"

"You must accept any interference, including that which results in  
undesired operation..."

In other words, don't complain if things don't work as you expected.

There are also the generic "instructions" included with every  
wireless device, which include helpful advice like "try re-orienting  
the antenna(s)" etc. We all throw these away of course.

The idea of trying 802.11A is reasonable, as it operates outside the  
2.4 Ghz. band. Using a 5.8Ghz cordless phone can help as well.

But no matter how well you "co-ordinate" your own house the fact is  
your neighbor can fire up a device that wreaks havoc on your gear,  
and there's nothing you can do about it.

The only real answer is to use equipment operating on commercial  
common-carrier frequencies which requires co-ordinating with other  
users of that spectrum. Not something most consumers are capable of  

Wireless is not the same as wired, no matter what the manufacturers  
might have you believe. The manufacturers all sell this "wireless"  
stuff like it was candy, and consumers expect that something they  
have paid for will work. But all frequencies are "shared" and once  
you put your signal into the atmosphere you are asking for all sorts  
of trouble. It's a miracle to me that these things work as well as  
they do.
