I was never a believer in Wi-Fi for the home, but I am now...

> I used to have CAT5 Ethernet for my 5 desktop PCs, but the long Ethernet
cables act as antennas... I couldn't afford the filters or the space to 
bring
that many ferrites and cable loops to my 8-port switch.

I am wrestling with that now with an extensive CAT-5e wired home network.  I 
have moved all the broadband routing equipment to my home office on the 
other side of the house from the shack, but the S3-S5 noise is still 
persistent.   Ferrites were placed on all cable ends and there is almost no 
reduction in noise.  Proximity between the home wiring and the outdoor 
antennas is a considerable factor.

I almost have too much invested to turn back now (mainly my time in a 
130-degree attic a few summers ago).  I have the 802.11g up and running 
anyway for when I want to roam the house with my laptop.   At some point, I 
may need to bite the bullet and convert everything over to 802.11g just to 
get past the cable radiation.
