Me: new iBook G4, v.92 modem and airport extreme card.

My wife: airport (dual ethernet) base station that is connected to her Indigo 350Mhz iMac via ethernet cable.

The problem: for years we have been using our phone lines and airport at v.34 speeds, because v.90 doesn't work for us. Lo and behold, when I get the new iBook I can connect at v.92 speeds every time with the internal modem.

Since Apple doesn't yet have v.92 for Airport (I called Applecare and asked), is it possible to use my iBook's internal modem and also allow my wife to surf the net from her iMac without using airport as the connection?

In other words, instead of using airport to call the ISP, use my iBook's modem to call and then allow both of us to surf because we are networked via airport?

Thanks!

yes... use internet connection sharing... you dont even need the airport base station then

Internet connection sharing doesn't work properly in Mac OS X 10.3 and not at all in 10.3.1. I hope this will be fixed with the next update, but at this time, it only works flawslessly in Jaguar (since 10.2.5 I guess).

Okay, walk me through this please

I turn on the Sharing from the internal modem to the airport on my iBook, and on my wife's iMac I turn it on as well? Her iMac doesn't have an airport card in it, remember, just the base station that is connected via ethernet. Does it still work? [Maybe that's why I thought it wouldn't work--I thought it must have an airport card installed on both machines to work.]

I thought I had done this before, but maybe I'm missing something. It will give me something to work on tomorrow

Thanks!

Turn on ICS only on the computer directly connected to the internet, not on the other computer.

I tried it--doesn't work (sorry). Maybe because the other computer doesn't have an airport card, just a base station on the ethernet. I tried turing on the ICS on her computer, too, and told it to look at the ethernet (for the base station) but no good.

Somebody on Apple's Discussion Board last night said I can't make it work, but maybe I'll call Apple next. Hell, that's why I'm paying the Big Bucks at Applecare for! *heh*

Thanks for your help anyway!

yea she would have to have a airport card in her computer

That's the sad problem: her iMac is the only model (of its time) that doesn't allow airport cards to be installed. That's why I have to go around this in a back-assward way...

Ok there may still be a way to do this... but I'm not 100% sure it'll work. First of all assign your iBook's airport card a static IP address outside the DHCP range that the Airport Base Station provides. Then also give the iMac a static IP (again outside DHCP range), but make it's default gateway (Apple calls it "Router" in the network prefs) the static IP address of the iBook. Make you can ping each other to assure connectivity. Turn connection sharing on the iBook (you should only need to do this once), and dial-up. Basically we're just using the Airport as a hub/bridge and the iBook as a router since it would be running natd (connection sharing) at this point. Good luck.

I think I tried it correctly, but said on the iMac that the address I assigned was in use (I made up the address on my iBook and applied it). Oh well, it isn't THAT important... just something I wanted to try

Thanks!

just curious the static IPs were different right? they can't be the same.

I thought they were supposed to be the same...

Anyway, I tried it again with different #s but no good. No biggie. Maybe I will play with it again later when I have time.

Each computer on your network must have a different IP number, but all the IP's must be on the same subnet. In other words, their IP numbers must be the same except for the last set of digits. You also have to specify your Router Address and the Subnet Mask (which is usually 255.255.255.0).
