Can the Airport Express share an already wireless connection?
Yes; the manual tells you how to do it.
Are you sure? I just asked on the Apple support pages and they say it
Here's my situation; when my team goes to a hotel we don't like paying
$15 for each person to access the internet.
So I bought a Linksys WTR54GS and its utter crap and must be replaced.
It crashes when there's a large download like from youtube or CNN video.
So I'm trying to share a hotel's wireless internet connection with four
other machines - also wirelessly.
Easy solution if you have at least two Macs, with only one additional
piece of equipement: an Ethernet cable.
Mac A connects to the hotel WiFi network, and has Internet Sharing
enabled to share from Airport to Ethernet.
Mac B connects to Mac A via Ethernet and has Internet Sharing enabled to
share from Ethernet to Airport, creating a new wireless network.
Any other computers connect to the wireless network created by Mac B.
Mac A will have a single NAT layer (hotel's) to the Internet.
Mac B will have double NAT, so some applications might not work properly
(e.g. iChat with audio/video chat).
Other computers will have triple NAT, which shouldn't be any worse than
The big disadvantage of this method is that the wireless network created
by Mac B is limited to WEP for its security.
If you want better security on your private WiFi network, then you just
need one Mac, an Airport Express and Ethernet cable.
One Mac connects to the hotel WiFi network and has Internet Sharing from
Airport to Ethernet.
The Airport Express connects to the Mac via Ethernet, and is set to
"Create a wireless network", with connection sharing "None (Bridge
All other computers then connect to your private wireless network. They
will all have double NAT. Mac A is doing the NAT and DHCP server for the
rest of the computers.
