- Surge Supressor??

While on dial-up, I passed the modem cable thru a surge
supressor. Dunno whether it actually worked, but never got
blindsided -- and here in NC we get tons of lightening.
Sooo ... should I pass the DSL cable (twixt the wall and
the modem) thru a surge supressor, or will that mess up
the DSL signals??

All you can do is try it and see. Some units will pass it ok, others
will not. Try downloading a big file, say Google Earth before and after
and make sure if it does work, it's no cutting your speed in half.
I'm in NC also and deal with grounding a LOT with the businesses I work
The single best thing you can do that's practical is to make sure your
phone and power (and cable) come into your house near each other and
that the phone demarc is grounded to the same earth ground as your
power. NOT to a wire ground on one of your power runs. This ties your
phones and electrical service to the same "ground stake" and any nearby
lightning generated voltage spikes will come into your house in step and
likely not bother you. Like two boats riding a big wave. If they are
close and connected they go up and down the wave together and are never
very far apart vertically.
Now lightning hitting your power pole or roof, well all bets are off.
The best comments I heard on this was the only perfect lightning
protection is the 12" of air space between the power and other cables
and the jacks on the wall when the cables are unplugged and lying on the

As DLR mentioned, try it and see what happens.
I tried running my DSL modem through a higher end APC surge protector (that
didn't say anything about DSL) and it killed the signal to my DSL modem.
Switched to an APC Back-UPS that did say it would work with DSL, and I
didn't see any attenuation or degradation of my DSL line.
Personally I use a surge protector - in fact, I'm hearing rumblings of
thunder again here in St. Paul, MN.
