Sharing internet through airport

Hi,
I have an iMac G4 with OSX 10.3 and a MacBook with OSX 10.4 and was wondering if it is possible to use the iMac kind of like an AirPort Base Station. The iMac is connected to the internet through ethernet via a router on a cable broadband connection.
I've used internet connect on the iMac to configure AirPort to share the internet and managed to connect the MacBook to the iMac but still can't seem to access the internet on the MacBook even though the Diagnostics have a green light on all of the options.
Would anyone have an idea as to why the webpages still arent loading?
Thanks for any help!

Did you enable Internet Sharing in the Sharing panel of the Control Panel.
You want to "share your connection from: Built-in Ethernet" to "computers using AirPort".

Can't connect to internet through Airport Express anymore

Suddenly, my PowerBook can't connect to the internet through Airport Express. Monday late afternoon--everything was fine. Put it in sleep, come back a few hours later, can't connect.
Thing is, Airport/wireless is working. Can stream audio to my home stereo.
And the DSL/modem are working. If I connect the machine via ethernet directly, I'm online.
Saw that some other users began having problems with USB/printer connections Monday. Could my problem be related?
What gives?
Any ideas?

Hello mnkyby. Welcome to the Apple Discussions!
It sounds like your AirPort Express Base Station (AX) in not getting a proper IP address from your modem.
Try this ...
o Connect to the AX's wireless network, and then, run the AirPort Admin Utility.
o Go to the Internet tab.
o Note the value for IP address. (Note: Do not list it here on the forum, just note what it is.)
o Is the IP address what you would expect from your ISP or is it something like: 196.254.x.x?
If the latter, try the following ...
Modem/Router Power Recycling - Quick
o Power-off the DSL/Cable modem, AX, & computer(s); Wait at least 5 minutes.
o Power-on the DSL/Cable modem; Wait at least 5 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the DSL/Cable modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the DSL/Cable modem; Wait at least 15 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)

Sharing internet through ethernet port

I'm sharing internet through my ethernet port to my other computer but so far it appears that it only works for web browsing. Is their something I can do (open a port or something) so the other computer can use the shared internet for more than just web browsing, like use ichat, Mail, or Dashboard?

Yes the firewall is on. Do I have to turn it completley off or can I just open a couple of ports?

Lost internet through airport

Somehow I have managed to lose the ability to connect to the internet through my airport extreme base station. In the system preferences I am told that I am connected to the network and that I am connected to the internet through Airport. Also, the PC that shares my network has no trouble joining the net but cannot connect to the internet.
I can reach the internet using the ethernet cable directly out of the modem.
In trying to achieve a solution I have altered many things in many places and am now very lost.
Can I start from scratch? If so how?
Help
Dave

Before starting from scratch, try simply resetting your connection. Connect the modem to the Base Station's ethernet WAN port (the port labelled with the "circle of dots" icon). Pull power to both the Base Station and the modem for at least five minutes. Then plug the modem into power and wait a minute. Then plug the Base Station into power and wait a minute. Restart your computers. Then try internet access again.
If you contine to have problems please post a new discussion topic in the Airport Extreme discussion forum rather than this forum.

Sharing Internet with AirPort

Hello
Okay to start my iMac here is connected directly to a DSL modem with no router through Ethernet. I saw that you can share Ethernet connections and use AirPort to create a Computer-to-Computer network and enable internet connection sharing. Would this work properly with a Windows XP computer with a wireless card in? I want to be able to get that computer on the net.

Yes, but you won't be able to use a password with an XP PC therefore is not recommended.
I would recommend getting a wireless router.

Mac connected but PC can't connect to internet through Airport Extreme

When I was using a dial-up connection everything worked fine on both computers but since I changed to a PPPoE / Ethernet connection my PC using Windows XP can't connect to the internet although is connected to the Airport with excellent signal.
In System Preferences>Network I have Connect using PPPoE option checked so I can't see my airport in the Airport Admin Utility. Apple Talk is Inactive.
In System Preferences>Sharing>Internet: Internet sharing is Off and there's a text that it can't be turned on "because there are no ports available over which to share your connection"

I understand, but for some reason, that I'm trying to
figure out, when I uncheck the PPPoE option on my
computer and my base station appears in the Admin
utility, I loose my internet connection on the
macintosh although the Network Status says that I'm
connected to the internet via Airport...
You will need to configure the Airport to connect via PPPoE.

Can't connect imac to internet through Airport Express

Hello
I am trying to connect my new imac (2.4Ghz,OS X 10.5) to the internet through my Airport Express (v6.3) but have encountered some problems.
The set up goes like this:
Cable Internet <wired> TP-LINK Router <wired> AE <wireless> imac
The internet is coming from my landlord on the bottom floor of my apartment so I can't change the router.
The router is assigning a static IP to my AE (192.168.5.101).
I am using WEP 128 bit security.
I have set the AE through Airport Utility to act as a Bridge.
On the imac I set the Network preferences to manually select an IP address (192.168.5.110) which is out of the range of the Router (192.168.5.101-108).
The AE connects and lights up green and the imac recognises the AE but I still cannot access the internet...
I have also tried to wirelessly connect my PC laptop to the AE using other static addresses but I still can't connect to the internet.
Can anyone please help??
Regards
Starwolfgang

Hello Starwolfgang. Welcome to the Apple Discussions!
The router is assigning a static IP to my AE (192.168.5.101).
Are you sure that this provided IP address is static? If so, you also need to note the provided DNS server(s) IPs as well.
On the imac I set the Network preferences to manually select an IP address (192.168.5.110) which is out of the range of the Router (192.168.5.101-108).
Since you configured your AX in bridge mode, your computer will be dependent on the NAT (& possibly DHCP) services provided by your apartment's router. Assuming that your landlord doesn't filter out any IP addresses and that the IP address you set is valid, you need to compare your iMac AirPort's DNS server address settings with that provided by your apartment's router to be sure they match.
Finally, assuming that your apartment provides you with an Ethernet jack, if you connect your iMac directly (via Ethernet) can it access the Internet?

Problems sharing internet over Airport extreme

I have a PowerBook G4 (OS 10.4.11) with a USB wireless broadband modem connected to the internet. I bought each of my daughters a MacBook (OS 10.5), and the idea was for me to have my laptop connected to the internet, then use internet sharing via my airport extreme card so that the girls could access the internet from my connection across airport.
I have no problem using my wireless broadband to connect to the internet. I have no problem firing up my airport extreme and creating the network, and I have no problem creating the internet share. I all seems to be working at my end. On the girls MacBooks, we have no problem firing up airport and connecting to the airport network I created. However, when we fire up safari, all we get it "you are not connected to the internet".
I'm lost. Any ideas?

cdelahoy, Welcome to the discussion area!
On your PowerBook G4 do you have the firewall enabled? If so, try go to System Preferences-> Sharing preference pane and enabling Personal Web Sharing. That should open the ports needed to give Internet access to the MacBooks.
If that doesn't work, try disabling the firewall on the PowerBook G4.

Lost connection to internet through airport

My Mac at home is configured to a timecapsule and connected through airport wifi. The Time capsule is connected via cable to modem and out via cable to Internet. Up until today everything is fine. started up and i have lost connection to the internet.
Network Preferences is showing that Airport has a self asssigned IP address and cannot connect to internet. The time capsule lights are showing green, as do the Modem, neither are reporting problems.
I have tried all of the "first Aid configurations" i.e. switch off/on etc, also tried a couple of ideas from forums, nothing works. I can connect the Mac directly to the modem via cable and access the internet.
As an aside, My iphone has also lost connectivity through home wifi.
It would appear from other forums that this is a growing problem, however not much in the way of resolution. Any Ideas????

Not connected to internet through airport xtreme (connection is ok) after upgrading iOS6

after upgrading to iOS6 none of my mobile devices (running iOS6) can go online on internet through my airport extreme. My MAC is using the same without problem.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Macbook to internet through Airport Express?

My G5 is connected to the internet through a wired router. I use Airtunes to wirelessly stream music from the G5 to my stereo. Is it possible to connect a Macbook wirelessly to the internet through the Airport Express and the G5?

Andesite, Welcome to the discussion area!
The AirPort Express (AX) will support up to 10 wireless clients so it can support both your G5 and a MacBook.

Trouble getting internet through Airport Express

I am trying to set up the most basic wireless network with a cable modem, Airport Express and G4 Powerbook running 10.4.6. I have went through all the steps of setting up the modem then the Airport Express and configuring it with Airport Admin. and all that. I get perfect signal from the express but when I open Safari it doesn't do anything. It doesn't come up with the network diagnostic "Not Connected to the Internet" screen or anything. When I plug my modem directly into the Powerbook through ethernet it works fine.
It seems as though I am just missing a step or an option or something like that.
I have also tried to use my roomates old Motorola WA480G wireless router with similar results. I can get Wi-Fi signal through the Airport card but Safari brings up the network diagnostic screen.
G4 Powerbook Mac OS X (10.4.6)
G4 Powerbook

I am having this exact same problem, only using a Dell laptop with Windows XP instead of a Mac. I had my Airport Express set up on a LAN at work a couple of months ago and it worked perfectly. It's been in storage for a couple of months, and now that I am trying to set it up at home with my cable modem, I can't get it to connect to the internet.
When I plug the modem in with an ethernet cable everything works perfectly. But when I plug it into the airport (after doing the power down/power up process) the LED goes solid green, but nothing will load in my browser. I can use other wireless networks without problem.
I also can't get it to print anymore. When I plug the printer directly into my computer it prints just fine. But when I plug it into the airport, it won't print. I've set the printer up using Bonjour, and the Airport Admin utility detects the printer. But when I print I get an error message saying that the printer failed to print the document.
Any ideas?

Can't connect to internet through Airport network

Previously - worked
Internet: DSL
Network: via Airport Extreme
Computers: 3 (G4 Tower, PowerBook G4, Xbox360)
Setup: I ran the ethernet cable out of the modem into the Aiport Extreme. Then I ran another ethernet cable into a router which then split the signal into two lines -- one going to the tower and one going to the Xbox. The laptop connected wirelessly. This worked using DHCP assigning multiple IP addresses to all on the network and indeed the two computers surfed the net with ease and I had no problems connecting or staying on Xbox Live.
Currently - doesn't work
Internet: Cable (Charter)
Network: same
Computers: same
Problem: I recently switched from DSL to Cable internet for faster speed. Here is what i found: When i connect the ethernet cable directly into the tower from the modem i can access the internet. If i connect the ethernet cable directly into the PowerBook G4 i get nothing. If i try to connect the ethernet cable to the Airport from the modem i get nothing as well. At first all i thought i had to do was change the account settings from that of the DSL to that of the Cable internet -- only there are no account settings for the Cable internet. I literally just plugged in the cable and was ready to go. I have tried resetting my airport to get rid of my previous [DSL] settings and redoing the Airport Setup Assistant to no avail.
G4 Tower, PowerBook G4 Mac OS X (10.3.9)

ok so i unplugged my modem for a few minutes and then plugged the ethernet into the airport and turned the modem back on. now i can get internet on both my laptop and my tower. that works, thanks!
an odd aside tho is that before, when i was connecting through PPPoE, the laptop would automatically connect to my network (regardless of how many networks the airport card was picking up). now that i have the airport set to just connect via ethernet i have to manually log onto my network every time. is there a setting i'm forgetting about that enables automatic log in or is this just the case with connecting via ethernet?
here is the next problem, though. i bought a wireless adapter for my 360 and it cannot detect my network. it detects two other different networks that are in my complex but not mine. i have no idea if this is an airport issue or a 360 issue as powerbooks just automatically detect an airport base station. i have tried testing it in the same room as the airport with no luck. the only way i have connected to Xbox Live so far was to hard line an ethernet cable to the 360, shut the modem off, turn it back on and connect that way. if anyone knows anything about the 360 or has had similar problems trying to get their 360 up and running wirelessly through an airport please let me know

How to use iBook for sharing internet via airport card... can it be done?

The title says most of it all. I want to share the internet coming from the wall through the airport card in my iBook. I've made it work, however I'm concerned about doing it securely. Can it be done securely? If so, how? I've read in the help files about using the firewalls and such, but I'm having trouble making heads or tails out of it all. How about a primer on basic wifi security in the iBook's Airport card environment? I'm not as savvy as I used to be! Thanks in advance for your help.

ride a bike:
Requirements for wireless Internet access
To use AirPort to access the Internet wirelessly using Mac OS X, you need:
An Apple AirPort Card, AirPort Extreme Card, or a compatible third-party wireless card
An AirPort Base Station, Time Capsule, AirPort Express, or an AirPort-enabled computer acting as a software base station (if you are hosting an AirPort wireless network)
Internet access
Some Internet service providers (ISPs) are not currently compatible with AirPort.
If you’re setting up an AirPort Base Station, Time Capsule, or AirPort Express to connect to the Internet, you need an account with an ISP. When you set up your account with your ISP, you were most likely given account information (such as user or account name, password, phone number, and possibly other information). Have this information ready when you set up your device.
If you are connecting your base station to an Ethernet network that already has an Internet connection, you may need an account name and password to access the network. Check with the network administrator if you’re not sure.

Cannot connect to internet through AirPort in Costa Rica - HELP!

Hello,
I have been traveling Costa Rica for the past few days, and have had no problem connecting to WIFI across the country, but, tonight, I am not able to connect. I clicked on my AirPort icon > Open Network Preferences. The Status reads "On", BUT under the status is a message that says:
"AirPort has the self-assigned IP address 169... and will not be able to connect to the internet."
Reading through the posts here, I have tried several fixes...
- Renew DHCP Lease
- Repair permissions
...And still no luck.
I have no access to the router itself, because I am staying at a bed and breakfast. Anyone have any other ideas?
I really appreciate your help in advance. I love this community!
Sincerely,
Nathan

Hey,
This is obviously seems to be a DHCP problem, do you have any other wireless devices with you like an iPhone, iPad or just any wireless capable device ? If yes, try to connect through it and see if it will obtain a valid IP address successfully, if it didn't, then surely it's a router issue that it isn't able to distribute IP addresses, if you don't have a second device, can you see any ethernet connections in the wall ? another solution is to contact the IT person at your location and ask him if you should configure your network settings manually and if so, what would be the settings. Sometimes something as simple as restarting the router fixes similar issues
