check the little connectivity icon in the task bar, it will then show "Local

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

up some of the equipment because I wanted to make sure that my laptop was
not vulnerable to "drive-by hackers." *They supposedly set a type of
security that is better than what I had done through Control Panel. *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.

A couple of things come to mind. One is a general comment on testing
routers, the other is more specific to your problem.

General comment:

You said: "I frequently...lose connection to cable and to the
Internet."

Which obviously means that sometimes you have a good connection.

You said: "He suspects that the router is at fault. However, he tested
the router and it responded correctly. Moreover, the
cable company was able to "ping" it from the home office. "

Which means the router was working when the tech tested it and when
the cable company pinged it.

Has the tech tested the router (from your side) when the cable/
internet *wasn't* working?
Has the cable company pinged it (from their side) when the cable/
internet *wasn't* working?

Not finding something wrong when the system is working doesn't mean
the router is OK. If it has an intermittent problem, the problem may
only show up - ready? - intermittently. :-)

Now, specific to your problem:

I'm assuming you have 2 routers: The LinkSys Wireless-G that you own,
and the cable company's router, right?
OK, you said "I frequently...lose connection to *cable* and to the
Internet."

If you are losing your cable connection at the same time, it can't be
your LinkSys router can it? Your cable TV doesn't go through the
LinkSys does it? If that's correct, then tell the cable to change
their router whether it passes their tests or not.
