Wireless Bridging

[Supersonic]

I'm trying to set up a little wireless network at home, but this particular
permutation sounds a bit different so if anyone can verify that this could
work, that'd be great.

I've cable broadband coming into the house, and have the supplied modem
that has to be used then wired into a Netgear wireless router (RP614)

Sitting right next to it is my 24" iMac with airport built in so the signal isnt
really going far!...

Downstairs is an elderly iBook, which i use with my plasma TV which is
headless/screenless, and once upon a time -did- have an airport card in it
until some klutz forgot that the screen bezel contained the airport antenna
(thats another story...) so no signal coming out of that any time soon...

Can I take the router and hardwire with an ethernet cable it into the iBook
and then hard wire the cable modem into my iMac and bridge between the
two wirelessly to transmit files and the usual?

If so...how does it need configuring?

In theory (assuming imac is always on) it should be possible depending on your router (some dont allow bridging) - not quite sure on how a mac would do it but a pc would need internet sharing enabled, however this looks like it could cover that.

Then it should be simple case of setting up ip addresses in the same range, the same dns/password etc is needed too.
So for example
modem: 192.168.1.1
imac: 192.168.1.2
router: 192.168.1.3 - makes sure this is in a bridging mode not set as an access point.
ibook: 192.168.1.4

Make sure the gateway is 192.168.1.1 if its needed.

But to be perfectly honest it would probably be easier to just buy a wireless bridge such as the airport express or similar and plug it into the ibook.
