Hello everyone,

I am part of a network in which everyone has static IPs. The gateway
is 192.168.0.1 and my IP is 192.168.0.28.

Ok now I have two LAN cards. 1st LAN is configured for the above
mentioned IP. 2nd LAN is for my home use. I use it to connect to my
brother's computer. No static IP for it, and i usually keep this LAN
connection disabled.

But when I enable it, my IP changes to 169.254.64.8. I know this by
PINGing myself. My brother's computer is running Win98 and he too
hasnt set any static IP. Although this changing of my IP doesnt cause
much harm, but my LAN chat program (Vypress) stops working. Why does
my IP changes to 164.x.x.x ?? Cant it remain 192.168.0.28 ?

And I would also like to know something more. I think data
communication between my computer and my bro's is slow. I think thats
because of dynamic IP. Can i make it static ? how ? Will it conflict
with my previous network and IP of the other LAN card ?

Thank you,
Faraz Azhar
 
Each NIC will have it's own address depending on how you
have configured them. You don't say how your home network
is set up eg. direct connection to another pc or via a
router etc.
If you are using a direct connection, this is why you
have a 169.254.x.x address - there is no dhcp server so
your computer configures itself. If you are connecting
through a router, then either dhcp isn't enabled on it or
there is a problem communicating with it.

You could set the second network card to have a static
address (right click the icon for it/properties/double
click TCP/IP and configure it here.) your brothers pc
will need to have an address in the same range and with
the same subnet mask in order for the two machines to
communicate.

This shouldn't conflict with your work one provided you
are using the correct card for each location.
 
ok.. ill set the static IPs. Ill set myself as 172.168.0.1 and my
bro's as 172.168.0.2. What about gateway ? do i need to set that too ?
