Re: Electrical Question

The problem isn't Neutral to ground differentials within the house,
it's the differential BETWEEN houses that is important. Anything over 1-2V
will likely cause problems. Signal voltage on 10BaseT is 0-5V. You may want
to switch to a fiber transceiver between the locations, then the voltage
differential is a non-issue.

If there is a 6V differential between House A and House B, then current WILL
flow from one house to the other. The one on the downstream side will see
a constant 6V signal on the line. LAN signalling will then be amplified
to 6V-11V, which is probably enough to fry delicate chips and circuitry
in your network card, short to your PCI bus and probably take out random
circuits on your mobo. Not pretty.

Spend the bucks and electrically isolate your drops. Even if they are fed
off of two separate feeders.

Also, multiple grounding points is also a bit tricky, as you may wind up
with a somewhat floating ground, also not good for IC circuitry.

Another option would be to go wireless with 802.11b if fiber is not an
option either. A simple Access Point, pigtail, LMR-400, and an antenna
setup can be had for about $300.

Otherwise, you may be replacing equipment on a regular basis, not to
mention the computers the networks connect to.
