Conecting 2 computers using built in airport. Sharing internet

Hi All....I would like to be able to share my cable modem connection to the internet with both my laptops. I have an ibook and an aluminum g4 powerbook. Can they be connected and share one internet connection? Through the airopt cards?
Thank you for any input.
Best...
Phil

I have an iBook G4 and we recently bought an iMac G5. We use dialup and AOL. We installed the AOL software on the new Mac and set up a additional account (because you can't use more than one screen name at a time). We are able to use the internet over Airport Extreme with dialup with very little loss of speed.
We do have printing problems. The iBook has to be turned on for the iMac's print jobs to get printed. That's why I'm here. But you should be able to do the internet as easily as we did. Joe

PS3 using BUILT-IN Airport on iMac???

Ok, so I'm trying to set up my PS3's network using wifi streaming from my iMac (sharing ethernet via wifi). I have all protection (wep/wpa) off. The iMac is transmitting (the arrow symbol is present on the wifi icon) and the PS3 can see the SSID when I scan for a network nearby, but when I try to connect it failed to obtain an IP address. Any clue? Please help!

The search function does work in this discussion area. The following is in my post in the thread "PS3 wireless connection via internet sharing":This may be related...
In the AirPort (wireless networking) discussion areas there have been several threads about trying to use a Mac's Internet Sharing to give a Nintendo Wii wireless access. To date, all of them have failed.
The result of the threads seems to point to the very strong possibility that the Wii uses ports that are not available/opened by Internet Sharing. Since there is no configuration options in this area on the Mac, there is no way to open these ports.
The general consensus is that a wireless router or access point must be used instead of the Mac's Internet Sharing.

MBP on G5 over airport sharing internet (Firewall issue)

Got my ADSL/router modem (intertex IX66 edflc) with two e/net ports feeding one PC and my G5 quad with airport fitted. Recently got a Mac book Pro. Originally i could not get my MBP to get an internet connection using dhcp from the G5. The for some odd reason i got one then lost it again. Then i regained it again so i noted the ip the MBP gained, it was 10.0.2.2 which i understand is what the G5 would issue when its sharing its internet connection. So i setup a manual Ip address, mask and router and i all worked very well. No dropouts or anything bad, apart from some more range from the quad would be nice.
However the problem with this story is that the MBP looses its internet connection (not Airport network) if i switch the G5 Firewall on. I have Personal web sharing on as required on both G5 & MBP.
So is it possible to get internet connection sharing from my G5 and still have my firewall on (as i don't like it off) ? I would have thought the elegance of OS X would allow me to get good wireless networking without having to kill my G5 firewall... Or am i doing something wrong ?
MBP & Quad all up to date with patches etc...

Niel - Thanks for the good suggestion.
When tracking the blocked ports in the logs, i noticed that the ports were constantly increasing upwards and so couldn't open them u. So i tried to revert the MBP to DHCP and after 60 seconds it hooked-up to the G5 even with the firewall on and all protective modes also on (stealth, udp blocked...?).
So with a little patience on start-up i get a good wifi connection, but when changing from one website to another there is a noticable delay as it loads-up. Each page has about a 3 second delay to load. Any ideas what's causing this ?

How do I use Mail on a shared internet connection

Hello All;
I've tried searching the forums, and either I'm using the wrong search terms, or this question is so basic no one else is having problems....
My wife and will sometimes be in a hotel that has an ethernet cable for internet access. We both travel with our laptops (sad life, I know...) and use the internet. We usually plug the cable into her MBP and then I set up internet sharing to my iBook. Which works fine, except that Mail can't make a connection and I have to check my email accounts by going to the browser interface for each. I have several, which is why I set Mail up to work with them. Not a big problem, but annoying. Finally, sitting here in Ottawa I decided to do something about it since I'm waiting for it to warm up a bit - its something like -20C this morning.
Is it as simple as turning off the MBP's firewall? Or adjusting it? I don't like playing with the security settings, if I don't have to, for her MBP because it is vital for her work.
We are both using 10.4.11, and as stated above - she has a Mac Book Pro and I'm using a G4 iBook.
Thanks in advance....
Brrrrr - its cold out there.....

Hello Seth.
I believe you must go to System Preferences > Sharing > Firewall on the computer that shares its Internet connection and enable the ports that Mail needs, i.e. click on the New button, choose Other from the Port Name popup menu to name that setting however you wish, and specify the port number(s) there.
Also, go to Apple Menu > System Preferences > Network, choose Network Port Configurations from the Show popup menu, and make sure that the configuration used to connect to Internet appears at the top of the list on each computer.

Sharing Internet connection/Using a macbook as a wireless bridge/router?

I was wondering if it is possible to connect a computer, or more specifically an Xbox 360 or PS2, into the MacBook's Ethernet port. Then somehow use the MacBook's AirPort to connect to my wireless router. Thus, this would make my MacBook some sort of bridge to my wireless router, so I could use my gaming systems to the internet.
I would like my set-up to be the following
PS2/XBox360 = Macbook >>> wireless >>> Router = Modem
I've explored the system preferences of Mac OSX, and noticed that in "Sharing," under the Internet Tab, there seems to be some way to share your connection. I've selected the options:
"Share your connection from: AirPort"
"To computers using: Built-in Ethernet"
My settings could be off, but it does not seem to work, although the description makes it seem entirely possible. If it does, this would save me money from having to try and buy another wireless router for my room, as we have no cable/Ethernet lines going to my second floor.
Any help on trying to figure this out, or reassure me if it does or doesn't work would be great. Thanks a lot!

Problems with sharing internet connection via usb

I have been sharing the internet connection on my iPhone 5 via usb to a PC for a few years. When updating to iOS 8.3 and iTunes to 12.1 (from iOS 6 if I remember correctly) the internet sharing through usb stopped working. Sharing through wifi works and settings are the same as when usb internet share did work. Any idea on how to solve this except downgrading?
For my troubleshooting, has anyone been able to share internet via usb to PC (or Mac) with iOS 8 / iTunes 12.
PS I have unliited cellular data and iPhone is my only internet connection at home,

Mark,
There is a excellent book that teaches you how to do this (and other things) called Mac OS X Tiger: The Missing Manual (others of course)
If I remember correctly (book is on loan)
1: System Preferences>Network>Show>network port configurations (click unlock)
2: Click>Built in Firewire and drag to the top of the list (why I forget why)
3: System Preferences>Sharing>Internet>Share your connection from: Built in Ethernet (or what your using for your connection in) >To computers using: Built in Firewire>Start
4: Mac #2>Hook up Firewire 400 cable>System Preferences>Network>Location>New Location
5: Show>Network Port Configurations>Drag Built in Firewire to top of list and enable.
6: I also think you have to enable Personal Web Sharing on the Mac hosting the internet.
anyway play with it, you'll figure it out. if someone doesn't get to you.

Sharing internet connection with another mac

I have a 2.33 GHz Intel Core Duo iMac with 2 GB memory running Leopard 10.5.1 and connect to the internet through a cable modem into my ethernet port. I have internet sharing and Airport on. My daughter has an iMac G4 running 10.3.9 and gets her internet connection through my computer through an Airport connection. This was working well until I upgraded to Leopard and now she is unable to connect. Either my computer does not show up on her list of available networks or it will show up only briefly. When it does show and she tries to connect, she gets an error message stating there is a problem connecting. Never happened before he Leopard upgrade. Any ideas?

Thanks again both...
I think I have done exactly as you suggest. The USB modem is in the MBA USB port and connects to the mobile signal giving a good, fast connection - allowing my MBA to use safari and mail very well and with good download speeds. I go in to system preferences, internet and network, sharing and internet sharing in the "share connection from" I choose ZTEUSBModem. In the "to computers using" I tick Airport. In airport options I've tried 40 and 128 bit WEP. The ipad sees a wireless network and connects using the password I set in the internet sharing, airport options section. However, if you try to look at a web page, it just sits there for a bit but doesn't work. I tried my Iphone 4 last night and got the same result. Both work fine with my usual home wifi network, just can't get them to play nice with this USB mobile broadband modem....
Thanks again for trying to help..

Sharing Internet with windows, connected by ethernet, using mac's airport

So I have a desktop that doesn't have Wi-Fi and I too cheap to buy anything for it. So I'm trying to use the MacBook's airport to give the Windows internet through the ethernet connecting them both.
I went to internet sharing and entered "Share connection from: Airport" "To computers using: ethernet." and that's all I got up to so far.

Now connect the two computers via an Ethernet Cable and you should have internet access on the PC.
Make sure you set up the PC to use the Ethernet port for network / internet use.

Can I use my built in airport network to sync to my apple tv?

I have an ibook. And Create a network with airport in the menu bar. But the apple tv doesn't show this network. I do not have a base station and i do not have the internet. But I have no touble finding the my ibook network with my imac.
The question is:
Can I use my built in airport in my mac to connect wireless to my apple tv?
ibook intel Mac OS X (10.4.9)

Well, I'm just using my Mac Mini's ariport to create a network between it and my AppleTV. No Airport Extreme base station or anything.
The reason his setup may not work is because he said he also has no internet... and the AppleTV needs an internet connection to function.
My biggest problem was: When I first tried my network, I wasn't able to get it to work unless I turned off my firewall entirely. (I had 'unblocked' all the required ports, but apparently the firewall would really only 'unblock' either the Internet OR the Ethernet, but not both for some reason (according to Mac Tech Support)... and since Internet sharing was required to get my AppleTV to the interet - no love.)
But now, for some reason, (maybe one of those recent OSX updates...) my network seems to work fine with my Firewall running (proper ports 'checked'), so I'm not complaining, and haven't had to invest in an Airport Extreme yet - which is nice, since my Airport signal is full strength coming from the Mini.

Need help sharing internet connection between pc and mac using airport

Hello
I have a PC with an internal modem that connects to the internet via 3g+. it's got wi-fi as my macbook.
i want to share the internet connection of the pc via wifi (using what is called an "ad hoc" connection ( a pc to pc network)) so that the mac can connect to the pc (via wifi) and use its internet connection.
i've already tried a bunch of things but they don't work, can someone help me or tell me where i can find a GOOD guide to do this? (i've already looked around but i haven't found anything that works)
thanks

Hi. I'm not sure if this helps, but I just found a nice way to do it the other ways around (share the internet from your mac with your pc).
See: http://echeng.com/journal/2009/07/06/encrypted-internet-sharing-between-mac-os-a nd-windows-xp/
Specifically, step 4 and 6 are crucial!:
1. In Mac OS X, enable Internet Sharing to computers using Airport
2. In AirPort Options, select 128-bit WEP encryption and enter a 13-character password
3. In Windows, add a new wireless network
4. Enter the SSID and select WEP encryption with Shared Network Authentication (not Open)
5. Uncheck “The key is provided automatically” and enter the 13-character password
6. In the Authentication tab, be sure that “Enable IEEE 802.1x authentication” is unchecked
The main idea is that MAC-WEP and PC-WEP are not quite the same, so this tweak makes them line up. Perhaps you can do it the other way around from PC to MAC by sort of reversing the idea?
Hope that helps you!

Can I set up a 2 (or 3) room audio system? I have iphone 3, iphone 4 and ipad 2 and need to know what hardware, if any, I need for this (airport express?, apple TV?) Also, would I use icloud or home sharing?

I need to know what hardware, if any, I need to do this (airport express?, apple TV?)
I simply want to send music from my itunes to 2 different rooms at the same time. Is it possible? I have iphone3, iphone4 and ipad2 if that helps.
Also, would I use icloud or home sharing? Sorry for the noob question, any help is appreciated.
Thanks!

The answer is not if you use iTunes.
The TC is NOT an iTunes server.. it is not a media device at all. It is a backup location for Time Machine.
You need a computer in the network which stores the iTunes library and you can then play it via the ipad.
A mini with a large USB drive plugged in will work fine.. it doesn't need to be new.. a couple of years old mini will work just as well.
As an extention to this, can we use multiple Airport expresses plugged into mutiple sound systems to simultaneously access different music from the same time capsule?
I am not sure.. there will be network limitations to this.
Look up how to use itunes in a network.

You would do better perhaps posting the question in iTunes section.. if as I guess you are actually using iTunes.

How to fix the "Two computers using the same IP address" issue on the airport express

I just bought an airport express and got dsl at my apartment, and I haven't been able to set up the wireless connection. My DSL works just fine but whenever I hook up the AX I get an error message saying that there are two computers using the same IP address on the network, but I only have one computer.
I know this is probably a simple fix, but I've never had this issue when I set up the Extreme at my parents house and I haven't been able to find a thread on this.
As of right now I have it set to Factory settings.
Help please!

This modem was designed to connect directly to a computer and you are trying to connect it to a router.
Unfortunately, this is not a simple fix as both the modem and your AirPort Express will need to be configured differently to work together correctly.
Connect the modem directly to your computer.
Open up your browser and type the default IP address for the modem into the address bar. Check your documentation on the modem but it is likely 192.168.1.254
That will bring up the configuration page for the modem.
You may need to enter the modem access code which is on a label on the back or bottom of the device
Look for an Advanced tab, then look for a tab labeled something like PPP Location
Right now, you will see that "PPP is on the modem"
Chance that to "PPP is on the computer or router"
Click to save your new settings and the modem will restart
If you ever need to get the modem back to its original settings, you will need to hold in the reset button on the back of the modem for 5-6 seconds and then enter in the default IP address to be able to access the settings on the modem
Connect the modem to the AirPort Express with an Ethernet cable
Open AirPort Utility on your Mac and click Continue to follow the guided setup to "Create a wireless network"
You may be asked to "switch" networks when you do this. You want to switch
Select the "Connect Using PPPoe" option when it appears
Enter your user name and password with your provider. Leave the Service Name area blank. You want to always stay connected if you see that option
Continue to follow the guided setup and Update to save settings
Pull the power cord from the modem, wait a moment, then restart the modem
Log on to the wireless network that you created during the setup and you should have an Internet connection

I cannot get my iMac with built-in airport to allow internet connections to Nook and PS3. The devices access the network, but internet connection fails. Internet sharing is enabled, network security (WEP, WPA) is completely off. What to check next?

I cannot get my iMac with built-in airport wi-fi to allow internet connections to Nook and PS3. The devices access the network, but internet connection fails. Internet sharing is enabled, network security (WEP, WPA) is disabled. What to check next?

On an additional note, I've purchased a wireless router and everything connected on the first attempt. It just vexes me that the built-in wireless isn't working as a router. Is this another example of "Mac only plays with Mac"?

Can you use Airport for internet and Gigabit Ethernet for file sharing?

i would like to complicate my network setup by using my Airport connection to the internet for internet access and then use the Gigabit Ethernet connection between my G5 tower and the MacBook Pro for file sharing, Compressor's distributed rendering, and possibly iTunes music/video sharing for Front Row.
is this possible? could i just run a cat 6 cable between the two and network them together? or do i need to get a Gigabit Switch?
i suppose i could just try running the cable between them and see what happens. i don't think these new machines require cross-over cables since the ethernet ports auto-detect that now, but is a cat 5e or cat 6 cable required for Gigabit speed?
thanks,
scott

Yes it would work. The Ethernet network would be used for local file transfers and the Airport for internet. However you will need to make sure Ethernet is at the top of the list of network ports in the Network Preferences.
