[X4U] Airport Express, old router & Xbox?

[Mark Des Cotes]

Hi all,

Not sure where to ask this question but I thought this was a good  
place to start.

My son has been asking me to get him the wireless transmitter for his  
Xbox 360 so that he can access Xbox Live. His Xbox is in the basement  
where there's no wired internet available.

I recently replaced my old 802.11b wireless router with an Airport  
Express. Can I hook the old router up to the Xbox and have it  
communicate wirelessly with the Airport Express which is in turn  
connected to my cable modem? I remember people on this list saying  
how they had multiple Airport Expresses to extend their range. This  
got me thinking that perhaps I can plug the old router into the Xbox  
and save myself the $100 or so for the wireless transmitter.

Can this be done? Is there anything I need to do to the old router  
first for this to work?

Thanks,

Mark
