Ethernet Wired Homes - Interference prone?

I've wired my own home with Cat5 and have no problems, in either direction.

I've got CAT5 Etherenet in my house (even in my shack) and have no
problems either way. CAT5 is balanced and very tightly twisted so
there is not a lot of leakage. You wouldn't want to run an antenna
right next to it, but it is fine for a normal installation.

I have several PC's wired to a hub router and ADSL, using cat 5
connections. No problems have been detected with RF noise.

Doug -

"Properly installed" should be NO problem

I installed miles of Cat 5 running Ethernet at a major hospital.

Due to ICU, Surgery, Radiology and Lab departments, we swept the entire area
for
any potential interference - which would interfere with patient support
equipment.

NONE. The industry does not need "urban legends"

"Properly installed" is the key aspect --- and their are a number of
certification organizations
for installers and contractors.

In my experience at home and at work, it's OK unless and untill a
hub, switch, or NIC decides to get noisy. Then it's time to get out
the handheld scanner and start tracking it down. The radio shop at
WeBuildHighways, my day job, had a bad switch, and it took a day to
find out what was trashing their VHF reception.

Aside from that, it's just fine.
