When you swap out the wall-wart, use your 12V or 13+V power supply if that
is appropriate.  I use my supply on my LINKSYS ROUTER with no problems!
FYI, some of my antennas are 20 ft above the router (and my shack!).

Yes. I include these power supplies in the list of potentially 
bad boxes. Also, try using ferrite chokes to suppress radiation 
from the power supply leads. The trash on the power leads can 
originate either on the Ethernet box or the power supply (or 

Another solution is to have one suitably-sized linear supply 
trickle-charging a battery that runs the gear. I'm gradually 
adopting this strategy as an alternative means of UPS for my 
computer networking infrastructure. In addition to the obvious 
noise reduction possibilities, conventional UPS units are power 
hogs. I've become quite conscious of this after moving from 
Chicago where I paid $0.10/kWh, to California, where I'm paying a 
graduated rate that hits $0.35/kWh.
