I am not an expert on this, and I may be missing something in your post. 
The way I am reading your post is that you are trying to hook two 
computers to the router with wireless adapter cards, right?  The way I 
understand the wireless network, if you have only two computers on the 
network, one should be hardwired to the router and the other one is 
connected by a wireless adapter, at least that is how my system works. I 
have one computer hardwired to my CNet Pro200WL PCI Fast Ethernet 
Adapter using a Linksys WRT54G and the other two desktops and the laptop 
all have wireless PCI network adapters. 
I have also found that using the live chat with Linksys is much more 
satisfactory than using emails. You can tell them what is happening and 
they can respond at once.  I have used this several times over the last 
4 years and has always solved the issue.  A transcript of the chat is 
sent to you as an email when done and I print it out for future reference.
Hope this helps.
