(Slightly OT) Very odd wireless networking problem

Hey,

First of all, I appologise for being slightly offtopic. I've tried
researching the solution to this answer and this is a kind of last
resort, so if someone can help me (without flaming) it'd be massivley
appreciated.

Essentially my Mac (10.4.9) has major issues connecting to my home
wireless network.

I run the following machines at home:
2x WinXP
1x Win2K3 Server
1x Linux box (desktop not server)
1x MacOS X

Where I live I'm unable to get any form of broadband other than
satellite so I'm stuck with dialup. I use my 2K3 server at DHCP and
dial up server (192.168.0.1 [gateway]), have my router set to not
function as DHCP and as such has a static IP (192.168.0.2).

When I'm on wireless, whether I'm running Linux or Windows, I have no
trouble accessing any network resources (shares, servers, internet,
etc) and DHCP allocates IP addresses automatically.

When I run my Mac on wireless, I can not get a DHCP allocated IP. When
I try to set networking information manually (IP, Gateway, subnet
mask) I have VERY VERY strange results. When I have another PC on
wireless, I can access only that PC from the Mac, none of the cabled
computers (NAS, file server, etc). With Linux and Windows I can access
both wired and wireless.

Does any one have any idea on what the hell is causing this? It makes
sense as to why DHCP isn't automatically giving an IP if it's having
trouble accessing the DHCP server which is wired to the network.

Much appreciate the replies.

For the wireless end, try 'alt.internet.wireless' which google does
carry. Be sure to identify make, model, and O/S version, or you aren't
going to get much help. As for the Mac, you're probably going to
have better luck over in one of the 'comp.sys.mac.*' groups.

That tells me either there is a firewall problem on the Mac blocking
DHCP, or the DHCP client isn't working. A remote possibility is a filter
of some kind on the wireless router.

This would suggest that the wireless router is ignoring the IP if it
wasn't the one to assign it. That could be a configuration setting on
the router. Can you tell the router to assign (grabbing a random number)
192.168.0.123 as a _static_ address, and then set the Mac to that value?

Scan the traffic in the 'alt.internet.wireless' newsgroup, and see if
anyone else has the problem. Obviously you'll need that make/model and
software version data.

Not enough details, and wrong newsgroup[s]. Good Luck
