Sharing Ethernet Connection Through Airport

Is it possible to share your Ethernet connection through airport so that two computers can connect to a single connection without the need of a wireless router? I know that this is possible on XP, but I am somewhat new with OS X and cannot seem to figure it out. Does anyone have any suggestions?

Open the Sharing preference, click on the Internet tab, select the connection to share from the drop down menu, then check the ports that will share the connection.
You will find additional info by selecting Mac Help from the Finder's Help menu and searching on the appropriate term.

Problems sharing internet connection through Airport with a PS3

Does anybody know how to share an internet connection wirelessly with a PS3? I've tried everything including following directions from the tech support people from both Sony and my ISP (Verizon) and nothing works. Last time I've talked to Verizon I've obtained a IP number from them as Sony recommended and that did not work either. Is anybody out there with a PS3 sharing the internet connection through Airport successfully? I'd really appreciate any help. Thanks.!!

Sharing ethernet connection with airport card from ( iMac 17" intel)

I have recently upgraded from a 800 15" iMac to a new 17" intel iMac - before the upgrade it would share the ethernet connection to the internet with sharing and broadcast the signal to my FW800 powerbook ( or any other mac in the house ( no problems)
Now with the new Imac set up I enable sharing ethernet connection to computers using airport ( same as before) I can see the computer ( sharing the connection) in the airport menu of my FW 800 PB - when I try and connect I get an error message ?
Looking for any tips or direction? I searched this forum ans apple support pages and did not find an answer... PB = OS 10.3.9 - Imac = OS 10.4.5

Hey thanks for the welcome!
The error message said " there is an error in connecting to ..."
OK ( after just checking it again) go figure - I turned off sharing ethernet connection to computers using airport on the iMac - and turned it back on and voila! I am now connected using the PB - ??? Must have been a reset issue?
lets see if this is a solid connection...
Thanks for the fast reply!

Problems sharing internet connection over airport

Hi everyone-
I've researched the heck out of the forums and still cant figure out what's happening with my system. I've got a MacBook Pro with OS 10.5.2. In previous OS versions (10.4) when I was successfully sharing my ethernet internet connection, the airport icon in the status bar showed a vertical "up" arrow, indicating that my connection was being shared.
I'm trying to do the same thing in OS 10.5.2 but not succeeding in getting the same notification. I'm finding that when I access the "Sharing" folder under "System Preferences" and select "Share your internet connection from: ethernet" and "To computers using: Airport" that both settings grey out, the "Internet Sharing" button turns green and the status says "On", but no sharing occurs. I've checked using other wireless laptops and a wifi finder, but no signal from my MacBook is ever found.
I've deleted my preferences folder to start fresh, no help. I've tried sharing from different ethernet sources, no help. It just feels like the problem is in the OS somewhere, not with the internet connection.
Any insight or help would be greatly appreciated! Thanks!

seems like i got the same issue as u and i just posted it:

Unabl eto share Internet connection through Airport

I have a new Samsung wave S8500. I'm trying to access the internet connection shared by my mac on the airport, everytime i try to connect to my mac through the Wi-Fi on my phone, it doesn't connect. I put a 40 bit WEP Key length on the sharing options. The airport can connect to my other phone which is a Nokia N97, the Samsung is able to connect directly to my friends Router(wi fi) and I'm able to use the net. I'm unable to pin point where the issue is.

First, before I get into too much detail: Is it even possible to set up a WPA2 network directly from the iMac without a separate router?
Welcome to Apple's discussion groups.
Despite the fact that WPA2 encryption has existed for years, Apple hasn't seen fit to include that option in its "Internet sharing" feature.

Connecting to shared internet connection through Mac osx 10.7 wifi

I can't get my new HP touch pad to connect to my wireless network. I connect my iMac through ethernet but have a wifi network setup from my iMac so my other devices can use my iMacs shared internet connection. The touchpad will not connect, it finds the network, I put in the WEP key and it states "unable to connect, try again". I am at the setup stage on the touch pad and can't get any further!!. I have tried everything I can think of including creating a new wireless network, disabling and changing the sharing password and re-enabling. all my other devices still log on fine and can connect to the internet through the iMacs connection. anyone got any ideas?
Post relates to: HP TouchPad (WiFi)

I just remembered why I ignored your first post when reading this topic:
Ad-hoc-sharing can't be the problem, because when I use the exact same method without any WEP encryption, so create an open network, it works perfectly - so it has to be an error in the webOS' handling of WEP or similar...
I'm curious that the Mac offers only ASCII (key length of 5 characters) or 128 bit encryption, but not 64bit (which has a key length of 10 hexadecimal characters and works perfectly with my touchpad). <Wiki definition of WEP.>
This sounds like an old problem we used to have when Palm came out with WiFi-enabled devices. Users would create an ASCII text password in their router, and it would generate a 10 character hexadecimal string that was the true password. Entering the 5-digit ASCII code would fail since it was a seed, and not the "real" code.. Entering the 10-digit key worked every time.
By any chance is this what is occurring on the Mac? Do you see a 10 digit code generated anywhere in the setup routine?
Was the link I provided to you of any help?

ITunes 10.6.3.25 on ethernet connection loses airport express speakers but iPhone 4 airplay works

Hi,
I have started experiencing a problem this past week (Aug 2012) that I see sometimes reported here. When I run iTunes 10.6.3.25 on a Win7 machine that is connected by ethernet to my router, the airport express speakers would regularly disappear. I can always connect to these airport express via airplay from my iPhone 4. In fact when the airplay speakers disappear from iTunes on the ethernet-connected machine, I can reliably make them reappear by turning on the Music app on the iPhone. But after a while the airplay speakers would disappear again. On a Win7 laptop connected via wifi to the network the same version of iTunes seems so far not to exhibit the same problem.
Has anyone discovered what the underlying problem is or found a solution?

I ran into the specific problem in another thread. There are more than 100 connections from the apple TV's to iTunes. You can do a netstat -a (windows or Mac), and verify the problem. iTunes is smart enough to stop allowing more than 100 connections but stupid to allow the ATV to create so many connections.
Now for what you really want! Set all of your ATVs to wifi only. Even setting the iTunes host to wifi might help also. I think that wifi is more unreliable, and forces connections to drop, keeping the count under 100.
I also turned off ip v6. That could help you also. I originally had problems on a Mac mini, and built a windows 7 box to try to fix the problem. The wifi trick worked on both platforms. Several of us have bug reports into apple. I have a wired house also, and am very angry to NEED to use slow wifi to overcome this problem. The ATV gen 3 has been able to keep up with 1080p over wifi, so it doesn't hurt too much. What really hurts is spending over 40 hours troubleshooting this bug.

Sharing Data & Printer Through Airport Extreem

My daughter is home for the summer and we are trying to get her MacBook working with the other computer in the house.
WIFI -- no problem. She is set up and going
Printer -- Half way there! We have a HP LaserJet P2015d printer plugged into the airport base.
I just tried to install that printer on her machine and we can print one sided but I can't seem to set up the duplex printing option. When I go to print / layout the two sided info is there but it is grey and I can't change. I wonder if I picked the wrong option when the machine wanted me to install the printer. When I opened the print browser in the System Preferences Print and Fax it offered me three versions of the HP P2015 -- one with a "Bonjour" connection and the other two with "Shared Printer" connection. I chose one of the latter. ...?
Data Sharing -- no idea. How do I set it up so we can share files between computers? My son has a PowerBook he set up where there is an icon in the dock that when you click the Finder shows my iMac's desktop as well as all his stuff. Of course I didn't pay any attention when they set that up and he isn't around right now to ask. (Somehow I did install the printer on that laptop and it can print duplex or one-sided. Again, damned if I can remember how I did that!)
We are all running OS X 10.4.11
Any Ideas?
Thanks

Simple start: Select Mac Help from the Finder's Help menu. Search for "printer sharing" and "file sharing" for numerous help articles on how to set up each.
If your printer is connected to an AEBS as you imply, then open Airport Utility, click on the Manual Setup button. Then click on the Printer icon in the toolbar. See that your printer is identified properly and turn on Print Sharing. Click on the Update button and wait for the AEBS to recycle.
Be sure you have installed the most recent printer driver. Either check HP's site for possible updated drivers or use the driver included with OS X, if any.

Ethernet connection and airport failure

I'm studying abroad in Madrid, Spain, and I'm having difficulty with my internet access. On campus, the IT director put in the airport location and password, and it won't log on. It says "failure to connect." Other Macs in the building are working fine, but mine. I noticed that when I open 'Internet Connect,' the status under Airport says "Computer to Computer." Also, at my residence, my ethernet connection is not working. I plugged in another Mac into my port, and it worked fine. I tried putting in the TCP/IP for Ethernet manually (IP Address, Subnet Mask, Router, and DNS servers), without success. I always get a message reading "unable to find host." Any help would be greatly appreciated!

Luz, talk to the IT staff, the base stations that you are using need to "know" your PB's card address, in the airport utility, how many base stations can you see? Also make sure that in the airport setting, you have removed the "allow this computer to create networks" tick, this can cause havoc in some networks and get your machine booted off.

Incredibly slow internet (Connected through airport)

Hey there!
I just got myself a new Macbook around 2 months ago and so far I'm very happy with it. I haven't had any problems except for one.
I'm connected to the internet wireless through Airport and since about a week ago loading web pages is going incredibly slow, whether I use Safari or Firefox. I didn't have this problem before and I didn't change any internet settings. Nothing else changed eigher. I'm still connected to the same network and I didn't install any dodgy programs on my network. Downloading or loading videos doesn't seem to be a problem though. When downloading from a fast server like mac or windows (I know I shouldn't but hey, all my friends use msn ;)) I can easily make the 300 kb/sec. Also waching video's on apple.com/trailers isn't a problem. It's only the loading of web pages or sending e-mails. It sometimes takes up to half a minute to even load google.com. I'm not sure but it might have started after a software update. not at all sure though! Can anybody help me please! Thanks!

Jop

Hi Jop, and Welcome to the discussions!
Two things to try first...
Fix Permissions using the Disk Utility, then reboot. or better yet, get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Try putting these in Network>TCP/IP>DNS Servers:
4.2.2.1
4.2.2.2
Might be better ones for you over there, but worth a try.

More ethernet connections for airport express

I am looking to hook up an ethernet switch to an Airport Express to provide additional ports to connect devices such as a printer (which doesn't want to function consistently in Wi-Fi mode), and possibly a Blu-Ray player. Any problems with my thinking here?

As long as you have verified that the Ethernet port has been enabled on lthe AirPort Express, you can connect an Ethernet switch to the Express to accommodate additional Ethernet devices.
Keep in mind that your "Ethernet" connections will only support as much bandwidth as the wireless network allows. This will likely be far less than a direct wired Ethernet cable connection from the main router to the Ethernet devices.

Devices not connecting through Airport extreme wired connection

Hi
I just got an Airport extreme to use as an extention of my existing network, and to plug some devices in so that they can connect to the internet for updates (Sony Blu-ray player, dish network receiver, slingbox)...
my wireless is from a linksys/cisco wireless router (4-port) wrt310n, that is connected to my cable modem. The airport is set and has the green light showing. The blu-ray player and dishnetwork receiver are plugged into two of the ports. The blu-ray player says it can't connect to the internet. The dish network receiver says it is connected, giving ip address/submask, etc.
If I take my macbook pro and turn off wireless and plug into the airport it will not connect to the internet.
What have I not done to allow wired connection to the airport extreme to connect to the net?
thanks
David

Thanks for the clarification of your setup.
Unfortunately, the bottom line here is that this is not going to work.
The ethernet ports on the Extreme will only be active if you configure the AirPort Extreme to "extend a wireless network". But, it can only "extend" a wireless network from another Apple router. It's not compatible for this purpose with your Cisco router or any other manufacturer's router.
If you are unable to connect the AirPort Extreme to your router using an ethernet cable, you might want to take a look at a pair of ethernet powerline adapters to accomplish the same task by using the wiring in your home to transmit the ethernet signal.
I should clarify that if you connect the Cisco and AirPort Extreme using ethernet, you would not use the "extend" setting on the AirPort Extreme. This is only used if the device is connecting to another Apple router.

Mac only sees part of external hard drive connected through airport extreme

I partitioned the Lacie 500gb external drive into a FAT32 portion, and a larger portion for Mac, per instructions so I can use by both Mac and PC. Mac is supposed to 'see' both partitions, but only sees the larger one. If i go through Airport Utility, manual setup, disks..then it does show both partitions. But the smaller partition does not show up on the desktop or in Finder, so I am unable to access it.
I need the smaller portion to show as well since that is the portion I will use with PC and to share files between PC and Mac. I researched 'mounting' the drive, but nothing there.
Thanks to anyone who can help...

Ethernet connection through thunderbolt cable

Hi
I've got a 27" Thunderbolt display where my mac mini is connected. In the back of the mini i've plugged the ethernet LAN cable in.
Once in a while I want to dock my Macbook Retina to the display and get 1) Bigger screen and 2) LAN connectivity
My questions:
1) If only connecting my macbook to the display via thunderbolt - can I get the ethernet connectivity which sits in the mac mini. Or do I have to connect with a separate Thunderbolt-LAN adaptor (i.e meaning two cables)
2) Does a thunderbolt cable exist with magsafe 2 (i.e similar to the cable that is in the display)
Kind regards
Frank, Denmark

1) If you want to dock your MBPr, it would be best to have the Display Ethernet connected;
2) ALL Thunderbolt Displays shipping after the Retina model came out were supposed to come with a MagSafe>MagSafe 2 adapter. If yours didn't, you can buy one for $10 or just go to your local Apple Store or an AASP and see if they will give you one.
