I am using mac leopard.

When connected to a wireless network using my airport, sometimes the network stops, and I get a 'self assigned ip"

The wireless network works for other people,  and it worked for me to before I got a "self-assigned-ip"

so I go to 'system preferences' -> 'network' -> 'advanced'-> 'tcp/ip'
and click 'renew dhcp lease'  and this sometimes corrects my 'self-assigned-ip'  (which always begins with a '1')

And sometimes my network stays as a 'self-assigned-ip'

Hmm, I assume that you may be losing the connection, and since the computer can no longer connect, it assigns itself an ip address.

So, when this happens do you still have a signal?

You could always try setting a static IP

i have access to the modem
i dont have a router


how on mac leopard, could i set a static IP
If you go to System Preferences > Network > Airport > Advanced > TCIP/IP and then choose the Configure IPv4 > Manually

And put in all of the correct info from when you do get a dynamic IP

Not the solution you were looking for? Getting a personalized solution is easy.

what does the sender do
It is not required, but you could make a static ip range on the router so that it doesn't try to hand out the static ip that you're taking. But as long as the lease on the address is taken by your computer, the router should be smart enough to not give that one out.

i dont have a router, I am plugged into the modem and share the internet

what should the giver do in mac "system preferences"
What do you mean by giver? Giver of the internet? That would be the modem. The only thing that you have to do is on the mac you are trying to use is set a static ip.
And the modem should do all of the routing functions that I was talking about. Unless you have something else handling DHCP.

Is this an ad-hoc network?

You keep referring to the "giver" of the internet. In most network schemes the giver would be the modem. These modems do not have OS's on them, therefor there is no reason for you to be configuring the static IP on them.

If say you have a linksys modem/router you can configure a static IP, however what i've been trying to tell you is that you only need to do this from the computer that you are having trouble with.
