AirPort Internet sharing problem

[Woolley, Darren]Darren Woolley - 12:31pm Oct 20, 2005 PST

I have a full AirPort system at home, but at not yet at work.

I ended up with a spare AirPort Extreme Card, so I brought it into work and installed in into my Dual 1.8 G5, with the hope of sharing the LAN net connection to my AirPort-capable laptop.

Following Take Control of Your AirPort Network's brief instructions, I used the Internet Sharing preferences to share the connection "from Built-in Ethernet" to "AirPort".

Unfortunately, while the Powerbook could see the network the G5 is creating, it reports that "There was an error joining the AirPort network".

The Take Control book specifically states on page A-1, that you don't need to create an ad-hoc or computer-to-computer network to be able to share, in fact you shouldn't - as the two are mutually exclusive. Apparently computer-to-computer networks are best if you _don't_ want to share a connection, only files or Bonjour chat etc.

Has anyone had this sort of configuration work successfully?



[Yes, though it's not something we do often, since sharing a connection via a computer is quite a bit flakier than using a base station. In fact, I just did it successfully here - the only quirk I noted that isn't in the book is that your AirPort adapter in the Network preference pane should be set to DHCP, or at least a unique IP address (mine isn't normally for reasons I won't go into here). If you're not even being able to connect to the network, that's probably an issue with channel selection or WEP passwords or something. -Adam]

I've made similar configurations work…did you remember to plug in the
Airport antenna to the back of the G5?

It should've come with the G5, and without it the Airport card's antenna
is nicely shielded from any RF radiation by the G5's case.

I just went and thoroughly checked the Airport Extreme card install. It's located
at the front of the G5, up above the RAM slots.

Was installed correctly - reseated to be sure, antenna cable attached correctly,
and antenna was installed on the back of the machine correctly....

cheers,

Darren

Re: AirPort Internet sharing problem

I had this type of setup running prior to buying an airport base station, using an iMacG5 as the host and pc and mac portables as the clients.

Don't forget that the firewalls on the client machines must be *off* for sharing to work?

They will be protected by the host machine's firewall upstream.

Re: AirPort Internet sharing problem

It may just be a software problem. I have had experiences like this where a network was misconfigured and failed once and it was then impossible to connect. Deleting some of the related files in your user Library will probably fix it: there are lots of discussions of AirPort connection problems on http://MacOSXhints.com with various solutions.
