Can't set up my airport card to share my internet connection with notebook

I have an iMac with an airport card -- I have a visitor with a notebook and I cannot set up a way to share the ethernet cable connection through my computer and airport card. No matter what I do it the Airport will always show "AirPort 5 has a self-assigned IP address and may not be able to connect to the Internet". I don't understand why it has a self-assigned IP -- I thought by using the internet sharing set-up that it simply duplicated a sharing of the modem through the built-in ethernet and using the same IP address. What am I doing wrong or is it just not possible to do it due to what my airport card allows? I am doing everything by the letter according to the instructions iMac G5 although I upgraded to Leopard operating system. Any advice? i do have an airport express but I can't understand why the airport card simply does not share my IP address.

The Airport Utility will only see (scan) the router if your PC is connected to it.
You may do the following.
1) Hard reset using the reset button on the router while plugged in. Keep pressed the button for 5 seconds to reset.
2) Connect to "Apple ..." network as shown in "View available wireless networks". Don't worry if you lose you connection to your existing matter. Your PC has already been setup to connect to your existing network and it takes only a click to connect to it. After you're done with Airport Express, your PC will automatically connect.
3) If still not successful, try opening network connection properties. Go to control panel, right click Network connections and select properties. Go to Wireless tab on the top and check if apple network is listed in your preferred networks. If not, try steps 1 and 2 until you find the network here. If it is listed here, open its properties and change encryption to "Disabled".
4) At this point, you should see it in Airport Utility.

Help setting up using my airport extreme to share my internet connection

I want to use my built-in airport extreme to share my internet connection with my PS3. I have a verizon aircard and have read on the internet that this can be done (but not necessarily with airport). I turned on internet sharing with airport and my ps3 reads my connection and obtains my ip address, but then it says could not connect to internet due to DNS server error.
Could someone run me down the process step-by-step so I can see what I'm doing wrong? Thanks for your help.
P.S. I have a iMac running on leopard if that matters.

ll959reds, Welcome to the discussion area!
Unfortunately the Internet Sharing provided by OS X does not provide nearly the configuration possibilities as even a very inexpensive wireless router.
Also if the firewall is enabled on the iMac, it applies equally to all ports including the AirPort (wireless) connection to the PS3. Therefore the firewall will block many of the requests from the PS3. To solve this issues, you would either need to disable the iMac's firewall or configure the iMac's firewall to allow connections via the AirPort side.
A much simpler solution is to use a wireless router instead of your iMac to provide the connection for the PS3.

How can I set up an Airport Extreme as a router, in conjunction with my AT&T modem/router?

I am trying to set up an Airport Extreme as my router, and I am currently using an AT&T modem/router combo. I am wondering what would be the easiest way to do this. Any help would be appreciated. Thanks!

Connect an Ethernet cable from one of the LAN <-> ports on the ATT modem/router to the WAN "O" port on the AirPort Extreme. This cable must remain in place permanently.
Open Macintosh HD > Applications > Utilities > AirPort Utility on your Mac
Click on Other WiFi Devices
Click on AirPort Extreme xxxxx
The utility will take a moment to analyze the connection, then a screen similar to this will appear with your AirPort Extreme instead of an AirPort Express
Type in a short simple name that you want to use for the wireless network
Type in a device name for the AirPort Extreme
Enter a password that will be used for both the AirPort Extreme and wireless network
Verify the password
Click Next
The utility will setup everything for you. When the message of Setup Complete appears, click Done and close AirPort Utility.
The AirPort Extreme wireless network is now available.

How to set up my airport extreme to share my net connection. i have a ethernet cable from my isp which when i use in my mac, i have to enter username

I access net through ethernet cable from my isp. so i just plug in the cable in my mac and in the browser it put the username & password. now i want to use my airport express to create a wireless network so i can access net from ipad and mac simultaneously. when i use airport express both my mac & ipad gets connected to airp exp but each of them ask for isp's username and password. i can only login from either one of them and access net in that one only. Pls advice???

To allow your Mac to "see" the HDD attached to an AirPort Extreme Base Station (AEBS) that is configured as a bridge, just be sure to assign a static Private IP address to the AEBS. By default the AEBS is a DHCP client and will get a dynamic IP address from the upstream router that is acting as the DHCP server. Since this address can change over time, it would make it more difficult for network clients to find the HDD.

Can a Powerbook running 10.4.11 share its internet connection with an iPhone 4s?

I have a 10-years-old Titanium PowerBook - still runs as good as new - with a Virgin Mobile 3G modem stuck in its backside. All my other Macs share the modem without any problems but my iPhone 4s doesn't seem to be able to. The iPhone logs onto the network like it should but every internet app on the phone tells me there's no connection.

Hello,
Sadly not as an iPhone 4 running iOS 6 or above needs Mac OS X 10.6.8 or higher to sync in iTunes.
Mac OS X 10.6 is not compatible with an PowerBook

Airport Card (802.11b) won't connect to network

Hello all...i've got another bizarre problem i can't seem to find a solution to.
I'm running a PMG4 2x867 MDD, with an older AirPort (801.11b), and i'm attempting to share an internet connection with a friend who lives in my building almost directly above me...y'know...split the cost and everything so everyone's happy. My problem is, after he gave me (and another friend) the password (13 characters, WEP), only i am unable to connect. The signal strength is good and all, but whenever i try to connect, i get the same error after a very brief pause: "...password is not correct..." Not, "...there was an error connecting..." i would suspect a signal issue if it was simply "...there was an error connecting..." i've double-checked that the password i'm using is correct, my other friend (using a newer, Intel Mac) has no trouble connecting, and i've tried everything from putting quotes around the password to converting the plain-text to hex and entering it. This is extremely frustrating. Anyone have any ideas, or had this problem before?

Okay, some progress:
After hours of googling and fussing with settings on the D-Link and Airport card, I discovered that this problem has a history with Apple/D-Link users, and one must set the "preamble length" in the router setup to "long." The default setting is "short."
Did that, and I was able to get through, but noticed that the signal range is very short, maybe 30 feet. Totally goes out in the other room. This never happened with the MacSense external card. I tried fooling around with the D-Link antennae and now have cut the signal altogether again and can't get back in.
I think it's time to buy an Airport base station, whatever the latest incarnation of it is. It's pretty frustrating know that there's probably some solution but it's buried deeply. Any ideas on how to get this operating more smoothly would be greatly appreciated!
Thanks in advance for any help,
Carlos Alden

Sharing an internet connection with Airport express and Time Capsule

Hi, I have been happily using a cable modem and a Time Capsule for my internet connection and wireless network. We recently added solar panels to our roof and the system needs to be connected to the internet so it can be monitored remotely. Calling Comcast is an exercise in frustration, and the solar people don't seem to know exactly how to do it, so I'm trying this.
We bought an Airport Express, thinking if it is connected with an ethernet cable to the solar system, it could somehow share the internet connection with the Time Capsule, or they could talk to each other. When I plug in the Airport Express, the only set-up option seems to be to set up a new network, which I don't think I want to do. Can anyone tell me how to set this up? Thank you!

Hi, Under Water.
You should configure the Express to "Join a wireless network" or to "Extend a wireless network". (Either one will work.)
Connect your computer to your Express via Ethernet and open AirPort Utility. Press "Manual Setup" and authenticate if necessary.
Go to the "Base Station" tab. Give the Express a name and password.
Go to the "Wireless" tab. Set the Wireless mode to "Join a wireless network" or "Extend a wireless network." Enter the name of the wireless network created by your Time Capsule (or select it from the list). Check the box that says "Allow Ethernet clients" (if you're joining) or "Allow Wireless Clients" (if you're extending).
Provide the appropriate security mode and password for the Time Capsule's network.
Press "Update" and allow your Express to restart.
Then you can plug the solar system into the Express's Ethernet port.

Sharing internet connection with powerbook and nintendo wii through airport

i have been trying to share my internet connection from my imac to my powerbook and nintendo wii. i've been unable to accomplish neither. i've opened the sharing preferences, chosen "share your connection from built in ethernet" which is how my imac is connected to the internet, and then chosen "to computers using airport". if i then set my airport options to automatic channel, encryption using 40 bit wep and set a 5 character password as it says if you "plan to share your internet connection with non-apple computers", (and then turn internet sharing on) shouldn't i be able to connect either/both my powerbook and my nintendo wii? or is it necessary to have some other piece of hardware or go through some other steps?
thanks in advance for any help.

I got a macbook for college and I had the same problem with connecting my Wii to the macbook's connection. But lo and behold, the internet's a wonderful place! I tried this out (http://www.macosxhints.com/article.php?story=20070514152251515) and it worked! I'm not sure about the powerbook bit though, sorry. Hope it works for you too.

How can I set up mhy Airport Express to extend my Time Capsule wifi wirelessly
Assuming that you have the model A1264 or A1392 version of the Express, it must be located where it can receive a strong wireless signal from the Time Capsule to be able to extend it correctly.
A good general location would be a point that is about half way between the Time Capsule and other area that needs more wireless coverage.
You will use AirPort Utility on your computer to configure the Express. An iPhone or iPad could be used as well.
We can provide more help....if you need it....but we'll need to know what version of AirPort Utility that you are using on your computer....or whether you want to use an iPhone or iPad to setup the Express.

I have a linksys WRT54G router that we use as a base. I want to use Airplay using Airport Express and hook up my stereo to it. How can i set up my Airport express without a PC/laptop? I just downloaded Airport utility on my iphone and ipad,will that work?

I have a linksys WRT54G router that we use as a base. I want to use Airplay using Airport Express and hook up my stereo to it. How can i set up my Airport express without a PC/laptop? I just downloaded Airport utility on my iphone and ipad,will that work? And one more thing about the setup, the linksys router shich acts as a base is in a different room as the airport express which i wanted to use for airplay. So I'm hoping to hook up the Airport express via wireless signal. If i can set it up, can someone pls help me out by posting detailed instructions. Thanks so much!

The first message that AirPort Utility will display during the auto setup will be that the Express will be confgured to "extend" the network. When AirPort Utility analyzes the network further, and sees that the Express cannot "extend" the 3rd party network, the next message will indicate that the Express is being configured to "join" the wireless network.
Once the Express is configured, if you later go into AirPort Utility to check the settings under the Wireless tab, you will see that the Wireless Mode is indeed "Join a wireless network".

Can I use the internal airport card of my Mac as a BRIDGE?

* My Mac is part of my home network.
* My wired Router provides NAT addressing for all wired computers and printers.
Question:
Can I use the internal airport card of my Mac as a BRIDGE?
I am able to create a second LAN where the internal airport card, creates it's own network, but then the wireless computers are not on the same network as the wired.
If using an Airport Express, there is an option you can uncheck "assign IP address" that turns it into a bridge.... Is there anything similar with os X 10.4.3

How can I change my internal airport card from G to N ???

I just want to know how can I change my internal airport card from G to N and how much that cost ?

The description of your machine (2 ghz MacBook) can describe maybe three different generations of the original polycarbonate MacBook.
If your machine is a Core 2 Duo MacBook that came out before the late 2007 models - $2.49 Canadian. It's all done in software, and won't work on the Core Duo models. The equivalent enabling software also comes on a disc if you get the latest 802.11n Apple AirPort Extreme or AirPort Express base stations.

Before you buy, you can check to see if your machine already has it.
