Macintosh computer cannot see d link wireless ??

Hi !!
We have a router d-link WBR 1310.

And our Macintosh computer (MAC OS X 10.4.11) cannot see our specific wireless, but can see all the other wireless in the neighbourhood.

With Ethernet cable, the Macintosh computer can connect to Internet without trouble.

We also have two PCs (with windows XP) we can connect to the router with the wireless connection and this connection is still excellent !


The technical support of D-link told us the configuration of the router was okay and the problem was with the Macintosh computer.

The technical support cannot help too...

Have you any advices ? any suggestion
Thanks !!

What kind of wireless security are you doing? Are you broadcasting the SSID? Can the Mac "see" the wireless router? What happens when you try connecting?
