Want to network my dually 1.25GHz G4, 1.5G RAM, OS 10.3.8 with my 14" iBook G3 800MHz 384M RAM, OS 10.3.6, both have Airport cards. I followed the Help instructions, both Airport cards are on, created a computer-to-computer network, both 'puters say they're connected to the same network, the card signals are strong, but I can't log on to the Internet from the laptop (the desktop has a cable modem), and neither 'puter shows the other on the desktop. I will say I made this work a few months ago but put the laptop away for awhile, so I don't know what I'm doing wrong now. Any ideas? Tips? Tricks?

What I hate about networking is the alchemy style-crap still leftover from when you were supposed to be a wizard to run this stuff.
First thing I would check is firewall settings on both systems. There may be a port setting or something else, there, that doesn't recognize the opposite machine.
I went nuts for an hour or so, last week, when I went to log in with my shiny new 12" PowerBook for the 1st time -- on the wi-fi-G home network. I forgot I had Mac filtering enabled and hadn't entered the MAC address of the laptop into the "allowed" file.

Oh boy. I barely understand your reply, even. I think I know what you're talking about, so I'll try that. I can totally relate to your first sentence, though. Thanks.

[cayugalad]

Actually the firewall is off on both machines. Any other directions anyone can point me in?

[cayugalad]

Okay, here's the latest. I discover that when I establish the network and confirm that airport is on on both machines and connected to the network, when I enable Internet Sharing on the desktop it disconnects from the network. No clue as to why. This whole thing is a stumper.

[Reboot]

Did you tell the laptop to share it's Internet through Airport, that's what it should be set to.

[cayugalad]

Yup.

[Reboot]

Turn off Internet Sharing. Connect to the Internet through the laptop and Ethernet DHCP. In Show: Network Port Configurations make sure Ethernet is at the top of the list, that's how you connect to the Internet, then try starting Internet Sharing over Airport in the laptop Sharing prefs. Make sure AppleTalkis off o n both machines so we're only dealing with TCP/IP connections. Can you do FileSharing between the machines now. You do know that Internet Sharing should only be turned on for the laptop, right?

[Reboot]

You can try deleting all your Network locations and setting up new ones, that's been known to cure Netowrk oddities.

[cayugalad]

Actually I think you've got it reversed. It's the desktop that has the ethernet connection to the Internet through a cable modem. However I followed your advice but reversed, and even deleted the network locations and created another. Still same problem of the computer-to-computer networking being broken when I turn on Internet Sharing, or not being able to establish one when Internet Sharing is on. I'm willing to try whatever you can come up with-I want this to work (it's why I got the freakin' laptop in the first place) /forums/ubbthreads/images/graemlins/mad.gif

why not spend a few bucks on a linksys or dlink wireless router.. plug that into your modem and your problems will be solved.
as I understand it, your connection is modem to one Mac with hardwire, and then the two Macs are connected to each other with AP.
so you are basically trying to use one IP address and go two ways to two machines wih it and no router/switch to help you. the mac in the middle is basically a bridge at that point.
can't fnd the post that was in this forum on someone else that was trying it.. i don't believe he had good results either, and he only wanted to connect to the internet and not fileshare.
personally, i say spend for the wireless router.

[cayugalad]

You're probably right, and that's what I'll probably end up doing, but the problem is a big burr under my saddle right now-I made it work a few months ago and it pisses me off that I can't do it now. I'm sure someone will say some silly-ass thing that I should have known and that will solve the problem. So? Anybody got anything silly-ass to say? I'm all ears. And thanks again.

Hey all-
Thanks for the input, here's the solution, from another forum, in case some other doofus asks the same question. BTW, the silly-ass step I forgot was turning on File Sharing.
In System prefs/Networking, turn on Airport and Ethernet in the Network Ports Configurations option on the machine with the Cable modem. Then turn on Internet Sharing in the Sharing Prefs Pane. Turn on File Sharing in both computers Sharing Prefs Pane. Then open a finder window on the iBook and click the Network Icon in the Finder SideBar and the other machine should show up as an Icon and you should now have internet on both.
Simple, yet a very specific series of steps to follow.

[Reboot]

LOL. Well we were warned by the title of your post. /forums/ubbthreads/images/graemlins/wink.gif
Glad you got it figured out. /forums/ubbthreads/images/graemlins/smile.gif
