Get rid of APIPA on mac broadcasting WiFi

Specs: Mac OS X 10.5, 50+ GB of RAM
OK, I have a mac laptop that is using Ethernet to connect to the internet. I'm trying to make the mac laptop broadcast an internet connection on WiFi (ICS). Sometimes it works, but most of the time, it fails and gives me APIPA. How do I fix this?

broadcast wifi?

Does your wifi card support WDS [wireless distribution system]?

From my experience wifi to wifi the only other way of doing it is create an adhoc network but that is one to one not one to many or many to one.

Usual way to solve apipa is to assign static ip addresses. But apipa is showing there is a lack of communication.

WDS... Im not really sure what that is. The wireless card is built in. By broadcast I mean, well, the laptop sends a wifi signal with an internet connection. Im not sure if that is WDS or ad-hoc. Your answer was kind of confusing.

And um, the website you posted was on topic, but it didnt help much because mine works sometimes but mostly doesn't. I'm pretty sure it's the APIPA, once it starts giving me that it doesnt work for a whole nother month. Talk about unstable wifi!

apipa is not the problem but the end result of the problem.

if you web search wds you will see its a distibution system where as adhoc is point to point.

According to x86 link you need to make an adhoc connection. The article does not mention what would act as a dhcp server which is where your problem originates.

It would appear your mac is not acting as a dhcp server for either itself or the pc.

This means you need to assign both static ips in the same subnet.

I would suggest the following since it will have the least chance of ip conflict. for the mac [no gateway since the mac is supposed to know to send it to the nic interface] for the pc with gateway entry and the same for dns.
both with subnet mask
