Airport no longer sharing internet

I have been using the airport extreme (802.11n) for several years, with few problems. Now it seems that it is only sharing the wireless connection from my modem to one computer at a time, rebooting the modem will allow any OTHER (or the same) computer to connect.
(I think it is something to do with the modem, but I am kind of hoping there is a known fix for this, on the AE)
Thanks for any help

I now believe that it is the AE, as I now have my mbp connected via ethernet and am able to connect my itouch via wireless. If i try and connect anything else via wireless it doesn't have an internet connection, but is on the network.
Also just noticed the orange light is flashing and in the airport util it says there are no DNS servers. Is this related?

Hi lfd58,
Are the ports of your computer working fine? Did you try other devices? Are you still using the sony reader software/reader for PC/MAC?

Airport network and sharing Internet connection

Hello all,
I have hit this problem with sharing an internet connection on an airport network. Maybe its a simple fix, maybe it a "can not be done", answer.
My set up may be a little hard to describe. To explain, completely wireless set up in my network, 1 x imac and 1 x powerbook, all on airport and using an airport express. This includes my new printer. All connected through airport express network, call it network A.
Up till now i had a modem with an ether net cable plugged into the airport express. All was fine.
I am in jakarta, the cable internet providers here are hopeless, slow connection speed.
Last month a new wireless internet service was released. Called 3.5 G. Its lightning fast and reliable. Basically you get a wireless USB modem attach it to your computer and you are always connected to the internet wirelessly. You can travel anywhere with it. The 3.5G is primarily for mobile phones but i use it just for internet. This modem is connected to my powerbook and works great.
Now, the useless cable internet connected to my airport express is still connected for my Imac to use.
My problem is that i would like to share my high speed internet connection from my laptop to my imac. Problem is that when i allow sharing from my laptop, the intenet works fine on both machines but on the powerbook, which is doing the sharing you get an arrow symbol through the airport icon at the top.
The laptop can NOT access the local airport express network A. Hence i cannot use the printer or see the imac. That is my problem, i cannot print from the powerbook unless i stop sharing. When you share an internet connection the sharing computer seems to create another computer to computer network and does not join the existing arirport network.
This is probably a little confusing. Hopefully, someone may have some ideas. My alternative is to buy a new fixed position modem/router for the 3.5G system. Its about $600. Ouch.
Any ideas
thanks for the interest.
joe

Selamat Phil Smith,
Actually do we know each other, cause i know a phil smith.
Actually an ether net cable is OK for the short term. But if i get another computer it may get complex. Spent a lot removing cables too.... Looks like i will have to buy the special modem router... Painful $600.
This share internet thing over airport looks like a great idea till you realise it disables access to the ariport network for the computer doing the sharing.
Cheers and thanks for the idea

Problem with Airport/Ethernet and Sharing Internet connection

I'm receiving my internet service through a wirless router. I am connected to it through Airport on my Mini. I am also connected to a dt G4 through a wired router (the G4 doesn't have airport). I want to share my connection from airport to the G4 on built in ethernet. On the mini I have internet sharing enabled (from airport to ethernet). I still cannot connect on the G4. Any ideas (should I disable dhcp on the router - tried that and it didn't work)?
10.4.8 on the Mini and 10.3.9 on the G4

Hi Jacob. Interesting setup.
1) If all the computers connect properly to the router, whether wired or wireless, why are you trying the internet sharing?
2) You mention a "dt g4" and an "MDD g4". I'm not a mac guy....are these different computers?
And.
Your mini's on wireless router. OK.
Your "dt g4" is on wired router...Same router?
If it's the same router, your network is something like this:
Internet
|
Router
| | |
#1 #2 3?
is that close?
If so, then you really don't need internet sharing.
Everone's "on", and if sharing is properly setup, all machines should "see" each other.

Airport Express, Leopard and Internet Sharing

I have my internet connection running directly to my iMac's ethernet connection and I use the Internet Sharing option to share my connection with computers. I had been using my Airport Express just to connect to my iMac for Airtunes. My Airport Express has stopped working and is not located unless I shut off Internet Sharing, but if I turn that off, it will not let me set the Airport Express to connect to an existing network - I guess because the network does not exist because I shut it off to configure the Airport Express. This is driving me crazy - any thoughts?

Interestingly, it works again. To initially configure the Airport Express, I had to shut off internet sharing. I configured the Airport Express (I did a hard reset to clear everything out) using the Airport Utility and set it to join an existing network. Of course my network did not show up since I had shut internet sharing off, but I manually typed in the name and password that I had already set for the internet sharing. I also put in a name and password for the base station, but this isn't required.
Then I hit update and right when it says that the configuration has been changed and it is waiting for the Airport Express to restart, I turned internet sharing back on. I waited and after flashing yellow for a while it connected. I unplugged it and plugged it back in to make sure it was fully configured and it works. I have found in the past the unplugging and plugging back in solves a lot of problems too.
Now that it is all set up, I can see and reconfigure the Airport Express in the Airport Utility even when internet sharing is on.
Hope this helps.

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.

System Preferences > Sharing > Internet
Share built-in-ethernet connection via Airport.

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.

Sharing internet with Windows over AirPort

My G5 tower is connected to typical home router via ethernet. This gives it flawless internet connectivity.
To give better wireless access to mobile devices that come to that room for a visit in the far corner of the house where the G5 is located, I got a used AirPort Extreme card for the G5 and installed it, making sure to attach the antenna connector and small t-shaped external antenna (provided with original G5) plugged in the back.
When I powered the G5 back on, it immediately saw the AE card and told me to review settings and press Apply. Under Network prefs, under "Location: Automatic", I chose "Show: AirPort." An AirPort ID is shown, along with the default setting below: "By default, join 'Automatic.'" I left all other network settings as they are--I am not trying to use AirPort to connect the G5 to the main wireless router, since it already has ethernet.
I went to the "Sharing" pref and chose the third pane under it, "Internet". I configured it to read: Share your connection from built-in ethernet . . . using (checkbox on) AirPort. I clicked on the AirPort options in this same pane, and typed in a network name: "ABC wi-fi". Channel is Automatic, and--to keep things simple for now--I left encryption off. I pressed OK to close that small dialog, then hit "Start" in the Sharing/Internet pane, which makes its status message change to "Internet sharing on: sharing your built-in ethernet connection." Success! Well, no.
The AirPort icon in the menu bar was a blank quarter-pie. So I clicked on it, and saw the "open internet sharing" option. A panel appeared where I could turn airport on. I did. The grayed-out Network line of the pane then showed the name of the network I had created back in the Sharing dialog: "ABC wi-fi." And the signal level indicator shows full power, all to the right. All set? Nope! When I go to my Windows laptop and find this new network, I see two new options: One, strangely, is the "Computer Name" shown in the Sharing pref panel, and clicking on it to connect doesn't work. The other option is the network I actually named and shared, "ABC wi-fi," but when I attempt to connect to it, Windows (actually Intel PROSet/Wireless Wi-Fi Connection Utility) insists on stepping me through a series of complex security settings, when it would seem that no security should be required since I didn't enable encryption on the AirPort connection.
Giving up on those security settings, I go back to the Sharing control panel and turn sharing off. I hit the AirPort options button and turn encryption on I leave on WEP 40-bit, which requires me to type in a five character string. I do so. I click OK and restart internet sharing. Again, I am given confirmation of "Internet sharing on: sharing your built-in ethernet connection." I try to connect from Windows again, but am not even presented with the complex security options. It just says "Unable to connect," even though it can clearly see the SSID. I try the same a few more times--no luck. I go get an iPod touch and select the new G5-based network--type in the five characters required for WEP 40-bit, and jump right on. Why can't my Windows 7 laptop connect?

Good advice from rccharles, do try that, but I'm wondering if it might be related to Digitally sign communications, even though this talks about server & connecting the other way...

System Preferences Sharing Internet Airport

System 10.4.11
In System Preferences>Sharing>Internet my wife's iBook lists three check box options: Built-in Ethernet, Built-in Firewire and Airport. My Powerbook with the same system does not list the Airport option. How can I add it? Thanks.

I've now found that on my Powerbook the Airport choice shows up if after the "Share your connection from" I chose something other than Airport. Not so with my wife's iBook Airport is always a choice. Now I am confused.

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!
17 G4 iMac 1.25ghz -> MacBook Pro 2.0ghz Mac OS X (10.4.5)

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".

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.

Airport no longer connects

Airport on my PowerBook doesn't connect. It was previously connecting to my Belkin Pre-N which quit again, and is again on it's way back to Belkin for repair. In the mean time, I've been connecting it to my iMac's airport through a shared connection, which no longer works now either. The PowerBook doesn't even recognize (see) my iMac's shared connection. It does see another wireless router that's within range and has a good signal strength, but it still wont connect to the internet.
I've had another post on here about why my powerbook can't connect through Apple Mail or iChat but will connect to the internet on Safari. Now, it wont connect to anything.

I'm confused. Wasn't the belkin the access point for your
airport/wifi/802.11/whatever network? When the belkin went
to the shop, did you set up the iMac as an access point and
connect it to your ISP? Or did you hook up the iMac to the DSL/
cable modem and then connect the powerbook with an
ethernet cable?

Yeah, I remember thinking that your powerbook was probably
still using the airport interface instead of the ethernet. You
were probably piggybacking on someone else's signal without
knowing it. Their server settings would have allowed you to
surf the web, but blocked smtp or chat services.
Before coming up with a solution we need to understand your
problem exactly. Fill us in on how things got set up after removing
the belkin.

IPhone accessing Mac Pro's shared internet via Bluetooth

I have an iPhone 4 which is running without an ATT contract (no cellular) and acting like an iPod.
I can access the Internet using the wifi arrangements on the iPhone, and this works easily.
But I would like to turn off the wifi on the iPhone and configure the iPhone to access the Internet
via the shared internet service on my Mac pro, connecting via bluetooth.
I am starting to think this is not possible, and the tethering can only go the other way, That is to
say that the iPhone can share it's cellular net access with the Mac via personal hotspot, or possibly
using bluetooth PAN or some other bluetooth connection service.
I have tried creating PAN network interfaces on the Mac Pro, and then I go to the iPhone and set
up a paired connection between the iPhone and the Mac Pro. But I just can't seem to guess the
right set of settings so that the iPhone can use the Mac Pro's internet via the PAN service.
Does PAN service only serve the iPhone's internet to an external device (like a notebook), or can
it be used in the other direction to allow the iPhone to request IP packet service from the Mac Pro?
Thoughts?

I've been having the same problems as everyone else here. Trying to share internet connection from my ethernet wired iMac to my MacBook and my iPhone. Tried all the workarounds, but nothing works, or lasts very long.
Yesterday, I finally talked with AppleCare for over an hour. All their suggestions (trashing preferences, changing settings, etc.) failed, as well. The AppleCare person then put me on hold to speak to an engineer, who told her that Snow Leopard no longer supports Internet Sharing as of 10.6.1.
Not willing to accept that answer, I had them set up an appointment at the Apple Store Genius Bar for me, and after chatting with the Genius for a while, he also confirmed that Internet Sharing is no longer supported under Snow Leopard. Apparently, there were many hardware issues that the engineers decided to circumvent, and so did not include support for Internet Sharing with the internal airport in Macs. They said that the Airport it is intended to receive, not to send a signals! Yet, it worked fine, doing just that, under Tiger and Leopard! The only fix he could offer was to wipe my drive and take me back to 10.5, which I declined.
However both the guy at the Genius Bar and the lady at AppleCare inferred that Apple "may" release another update to fix this issue, if they get enough complaints and bug reports.
So, there you have it. Apple no longer officially supports Internet Sharing in Snow Leopard.

Sharing internet: Mac OSX 10.5 and WinMobile 6 (HTC) device

Hello there,
I've recently bought an HTC Touch, running WinMobile 6.0. Right out of the box it connected seamlessly with my iMac running 10.5, and is now happily sharing the internet connection (the ethernet is shared through airport). This enables me to synchronise with Exchange without the need for active gprs or edge all the time, and i can surf using the htc.
I bought a second HTC touch for a collegue, who runs MacOSX 10.5 on a Macbook Pro. Same story, sharing internet, all settings identical. Both HTC's "connect" to the shared internet, though have no access to the internet.
The second HTC does connect to my iMac's shared internet connection.
We've tried loads of settings but can't figure out how to make the bloody thing work.
We both upgraded from OSX 10.4.x to 10.5.1, so perhaps a long lost setting is preventing the system from working properly?
Any advice and tips?

Hi s2foster2, well I am certainly willing to try to help you, just don't know if I can be much help because I am not very
familiar with Mac. I was able to help a couple of people but that was due to them being able to send me screenshots.
I understand Flash Player but where programs, add ons, ActiveX Controls, even where the Flash files are located I don't know. I do know Mac has a Library:-)
Some new information has come to light tonight however, by one of our most helpful people on the forum. This was about
the 3rd party content, etc.
I looked at your FF add ons and you have the SWF and it's correct. Do you know where the Flash files are and could you
post back all of the Flash files with version numbers? That will tell me if Flash Player is installed with the correct files.
We can have a go at this if you want. I can tell you what info I need as long as you know where to find it, because I don't.
Let me know,
thanks,

Hi, My network went down earlier in the week. Now it is fine, but my macbook airport no longer detects it and keeps asking for a WAP. When I put the password in, it 'times out'. I'm getting rather fed up.

Hi, My network went down earlier in the week. Now the network is fine, I can connect through the ethernet cable, but my macbook airport no longer detects it, when prompted, macbook will find it, but I get asked for the WAP. When I put the password in, it 'times out'. Prior to the network problem my macbook worked fine everytime. Anyone know the answer?

My guess is all the issues are probably related and fall back to malware.
AVG is probably correct in identifying malware. So I suggest you try some cleaning tools other than Emsisoft .
ones I use (all of them one after the other until I find one that can cope) are;
Roguekiller http://www.adlice.com/softwares/roguekiller/
Malwarebytes anti malware Free http://www.malwarebytes.org/mwb-download/var2/confirm/
ESET online scanner http://www.eset.com/int/home/products/online-scanner/
So first create a clean boot in Windows using Microsoft's instructions https://support.microsoft.com/kb/929135?wa=wsignin1.0 and then run the anti malware applications.
My outside looking in guess is that malware has set itself up as an internet proxy and is is downloading copies of itself and other malware, blocking some mail port as times as downloading more malware is more important, and probably breaking your tivo as well..
Try the malware programs first. If that does not work I will try and talk you through some logging to see what is happening.

Airport no longer working only on a single mbp on a single home-network

Hello fellows
Been recently foghting with this strnge,unreported issue,
The macbook pro is a 13" mid 2012 series.
The network router is a D-Link XXXXXXXXXXXX with DSL flat line.
All the other machines in there are just working FINE (1 15"2009 mbpro, 2 12" 2005 ibooks, 2 windows computers,2 tablets, 4 mobile phones) all connected by the same wifi
The faulty macbook pro doesn't connect either on airport and ethernet, a exclamative point icon appears on the top right after turning wifi on.
Until yesterday by sharing internet connection with the ither macbook or ibooks and hook it up via ethernet the connection was working, it stoppped suddenly like the way the airport malfunction started.
On other wifi networks, mobile tethering, on the 13" works perfectly.
Thanks in advance
