[AccessD] OT - Home networking question

Hi Doug:

Off the top, as you appears to be using a simple work-group type network,
with no servers, the first things to check if a computer is not seeing the
network, would be one of three items:

1. The workgroup name has to be the same on all your computers.
2. The IP range has to be the same i.e. 192.168.177.xxx where xxx is a
different value for every computer on the network. (Note: the value 177 can
be any number but it also must be consistent network wide)
3. The subnet mask usually defaults to 255.255.255.0...check for a key-in
error.

If these items are checked and are consistent then we have to look at the
router configuration and whether you are using your ISP as your domain
controller which will make it a whole different ball of wax.

HTH
Jim

Subject: [AccessD] OT - Home networking question

Folks,

I know there are several members of this group who are knowledgeable about
computer networking. We have a network in our home/offices that has evolved
over time. The basic configuration is that out of our cable modem there is
an Ethernet hub. 3 cables come out of this hub and go to routers, one in my
office in one part of the house, one in my wife's office, and one to our
wifi. These have been added as requirements came about so this probably
isn't the best configuration. At the present we don't use the network to
access machines in other parts of the system. I have several in my office
that access each other, but they are on the same router.  I do want to stay
with the wired systems to the offices.  We just added a home security system
that can be monitored over the network. It is connected to my router as it
is closest to the box. I can access the system by typing in it's IP address.
Now I am trying to access it from other points in the network and the IP is
not visible. As you can probably tell I am network challenged. I think what
I need to do is find the IP address of the security system from outside my
router. How can this be done? 

Thanks 

Doug
