Hi,

I'm no expert on wireless but it sounds like the bridge should be in
AP mode if poss and connected to something to do some routing. This
could be a router or even an old laptop.

For a starter you could try setting the bridge to AP mode then running
a proxy on your laptop connected to the bridge via ethernet. Then try
getting another laptop to connect to the AP and use the proxy to get
out to the internet.

If the bridge can't act as an AP you could try having an old laptop to
connect to the bridge then a separate 'ad hoc' connection between that
and your other laptop. Maybe an AP and router could connect directly
to the bridge.

Best to find out if the bridge can act as an AP or connect directly to
an AP and take it from there.

cheers,
Pete.
