Since we are on the subject.  Does anyone have an opinion on shielded
Ethernet vs not shielded?  I used to be a small voltage tech for the cable
company and I did a lot of cat5-6 installs for other jobs and almost never
used shielded Ethernet. I’ve been told that it doesn’t matter but I’m
having my doubts lately.  I am suspecting that my HF signals are
interfering with my networking as well. It can certainly knock the wireless
router out if commission.  I’m thinking of replacing every networking cable
with shielded cat6.
