The cable company technician changed the splitters "just in case," with no

There is no reason you need a network tech at your house to set up a
wireless router. Millions do it right out of the box. There is no
security that a network tech is going to enable beyond that which
comes with the equipment and the std setup can be used to enabe. The
key is to make sure you put security keys into the wireless router and
any wireless connected PC's and make sure the encryption is turned on.





*So, I
really hate to do that unless I can be fairly certain that the router is at
fault. *Incidentally, I have a lot of experience with several types of
software, but I have absolutely no knowledge of hardware and would not even
be comfortable with software that involved editing the Registry.

One thing the SuddenLink technician said surprised and confused me: He said
that they "preferred" that homeowners not use *any type* of surge
suppressor. *He did not request that I disconnect mine, but I don't
understand that statement. *Does anyone know why the cable company would
take that position. *He also said, "They don't do any good anyway."
Actually, I had a small surge suppressor that proved its worth a few years
ago. *My microwave would not work after a major thunderstorm, and I thought
it was ruined. *It turned out that the surge suppressor had been destroyed,
but it had done its job -- the microwave worked perfectly after I discarded
that surge suppressor.

First question is what exactly goes through the surge protector. Does
it include the coax cable from the cable modem, or just the power?
For protection against surges, both should go through the same surge
protector. I have not heard of any issues related to surge protectors
and cable performance. Also, since the cable folks were out there,
they should have been able to measure the signal strength at the cable
modem. Actually, that can be done right from the PC or remotely as
well.

In any case, if you want to rule out that it has anything to do with
the surge protection, just temporarily eliminate the one you may have
the cable modem routed through. For that matter, you could just
eliminate all the ones connected to any of the PC, router, etc.

Also, cable modems have status lights on the front. What do they
show when you're having this problem? If there is a signal problem
between the cable modem and the cable network, the online, send,
receive ligts wlll generally go out. Then the modem recovers and
you'll see the receive, transmit, then online lights come back on in
that order. If that is happening, then something is wrong either
with the signal from the cable system to the modem or the modem
itself. If it's not happening, then it suggest it's probably not the
modem and something could be wrong with the router.

Also, look in the manual for the cable modem, their website or google
online. The cable modems have an IP address that you can just put
into your browser and pull up the internals for the modem. That will
show you many things, including it's error log. The error log will
show what time it lost signal, last rebooted, etc. This is also
accessible remotely, so the folks at the cable company should be able
to tell you if the modem shows hickup when you're seeing the
connection loss at your PC.

Consider how many splits you have on the cable signal coming in.
Where possible it's recommended that the incoming signal be divided
once, with one leg then going to the cable modem, the other gets split
as needed for TV.
