Can't share internet over airport anymore

I’ve got DSL hardwired to a G5.
It has an airport that used to share my internet connection wirelessly to several laptops.
The other day, I restarted the tower, and I was unable to reconnect to the web from the laptops.
The little airport icon with the antenna/up arrow doesn't show up anymore.
I can use the airport on the tower – the card still seems to work so that’s not it. Something in my G5 system (10.4.6) won’t allow internet sharing to airports anymore.
HELP
Eric

Have you gone to system preferences -->sharing-->internet
check to see if it is switched on.

How to share files over Airport Extreme?

I have a G4 iMac connected to the Internet via an Airport Extreme. I also have an eMac in another room which can access the internet over the same Airport Extreme.
I have created a video file on the eMac but I need to burn it to DVD which means I need to get it to the iMac.
I know I should be able to send it over the network but each Mac can't seem to see the other, if you get my meaning. I have tried to switch on File Sharing and such like but I wonder if I am doing something wrong. Should there be an icon on the iMac desktop representing the eMac or something and vice versa? If that should be the case, I haven't got this.
If anyone can point me in the right direction to get File Sharing set up between my two Macs, I would be most grateful.
PS The eMac can access the internet just fine and use the iMac's Printer if it needs to.

Try these suggestions (copied from another discussion) which cover two alternative ways for getting file sharing between two Macs to work:
The first step is: on each computer, go into System Preferences, then Sharing, and turn on "Personal File Sharing". On that page, you'll see, at the top, the computer's name (which you can change), and at the bottom, the IP number (eg 10.0.1.2), which you may need as an alternative.
Then, on each computer, go to Finder, then click on Network. You may straightaway see the other computer appear - you can click on it, click "Connect", and then either log in as a user (it has to be a user that's been set up on that machine), or a guest.
As a guest, you can access all Public folders on the computer.
As a user, you can access that user's Home folder
As an admin user, you can access the whole hard drive.
So, if you have different user accounts set up on the computers, it's best to use Guest access and then put the files you're sharing in your user's Public folder.
Now, if that computer doesn't immediately appear, go to the Finder, click cmd-K (to open the Connect to Server dialogue), and type in
afp://ip-address-of-other-computer
eg afp://10.0.1.2
You'll then get the same login dialogue as above.

VPN - can't access internet over VPN

Hi,
I have an issue with VPN.
For my work I need to be able to log into my office network remotely and then access remote desktop connection from within my work network.
This won't work unless I am accessing the internet from inside the VPN.
I have got this working on a PC, just had to select "Use default gateway on remote network" and now when I access the VPN on a windows laptop I am accessing the internet over the VPN.
When I connect to the VPN on the Mac I can access the network, email server, file servers etc, but can not access the internet through the VPN.
I have tried:
- changing the service order
- ticking and unpicking the send all traffic over VPN setting
I can get to the point where I can access my work network over the VPN while also accessing the internet over my wifi but cannot get it so I can access the internet over the VPN connection. It is a PPTP VPN.
Does anyone know how I get my Mac to use the default gateway on the remote network?

If this server is behind a (NAT-) router you need to turn on "ipforwarding only" in Server Admin NAT configuration otherwise the server wont route packets beyond it's subnet.

IOS7 (iPad or iPhone) can't play music over airport

iOS7 (iPad or iPhone) can't play music over airport? I don't see the little arro that let's me pick the airport for music to the audio system.

New way of doing this is to sweep your finger up from the bottom of the iPhone screen; you see a sort of control panel with things like airplane mode, bluetooth etc across the top. And 3/4 of the way down the little arrow thing you used to see beside in "music" to choose the AirPlay or Base Station.
Not exactly intuitive.

IMac G5 isight Can No longer connect to internet over Airport

I have an iMac G5 that has been working fine on my Airport Extreme wireless network for 3 years. Suddenly, I can no longer access the internet over my Airport connection. The computer is on my local Airport network wirelessly (I can access it from my laptop and share files). I can connect to the internet from 4 other computers connected to the same wireless Airport network (2 MacBook Pro's, 1 Powermac G4). In addition, if I connect my iMac to my laptop via a twisted pair ethernet cable and turn on internet sharing on my laptop, my iMac can connect to the internet. All systems are running 10.5.5 and no firewalls in place. I checked my internet preferences and they have not been changed from what they were before when it was working. DOES ANYONE HAVE ANY IDEA WHY SUDDENLY IT STOPPED CONNECTING TO THE INTERNET OVER MY WIRELESS AIRPORT CONNECTION?

I have just experienced the same situation. Everything was working fine and now I can't connect to my airport from my macbook pro. I also have an iMac G5 working perfectly well on the same airport.
Could it be a latest update that has caused the problem?

Suggest that you cross-post in the AirPort Forums

Can't share Internet from Mac to AirPort Extreme via Thunderbolt Ethernet

Hey there!
I'm trying to essentially use a 2013 AirPort Extreme as an AP for the network. It's connected via WAN to a Mac via a Thunderbolt to Ethernet adapter.
I'm having a hard time telling OS X (10.10)/ OS X Server that I want it to take the Internet from "iPhone USB" and share it with "Thunderbolt Ethernet". With or without OS X Server's DHCP/DNS "help". I've been experiencing issues with Internet Sharing for years on OS X, so the fact that I'm having an issue today is no surprise, I'm just hoping someone out there has a solution.
If I go back to Internet Sharing in System Preferences, the "share Internet connection from" combo box is blank, rather than showing "iPhone USB".
Also, I'm unsure as to whether I should be using OS X Server... I know it's not necessary for simple Internet connection sharing, but I'd like to use DHCP and DNS services with this setup at least eventually.... Obviously just getting Internet to the AirPort is first-priority.
Any ideas?

Hello Kevin,
Let me try to get this straight, it seems like you want to bridge the fee-based wifi network and your home wireless network using your MB.
I don't know if you have done the following steps already on your MB:
1) Choose Apple > System Preferences, and then click Sharing.
2) Select Internet Sharing.
3) Choose a network service from the “Share your connection from” pop-up menu, AirPort in your case.
4) Select a networking service to share your Internet connection from the “To computers using” list, ethernet in your case.
Sorry, yes indeed it is straight from Mac Help titled "Sharing your Internet connection." and it sounds like you have done the sharing part already. You wrote about something wrong with your MB. It might be helpful to write what is wrong with your MB, AirPort Extreme, or your "other computers." Preciseness can definably help us help you.
May you solve the problem.

Can't share internet with iPhone4 via Airport with MacBook Pro on Ethernet

I'm in Iraq being abused by a criminal ISP offering 256K (yes, kilobytes per second!) connectivity via a cat IV ethernet cable to my MacBook Pro (OS X 10.5.9). I have a first-gen iPhone4 (16G, version 4.2.1), it will not connect to the internet via airport to my MacBook. I'm getting a good wi-fi symbol on my iPhone, the Airport is correctly finding my MacBook's network, and it properly demands/accepts my WEP password. But I cannot get mail, go on line or use any apps.
Under the DHCP tab on my MacBook's network on the iPhone's Settings/Wi-Fi page...I have a good IP Address and Subnet Mask. Previously I've also had numbers show up on the Router and DNS lines as well...but they are now blank. I have never had numbers on the Search Domains or Client ID lines.
Can anyone tell me what's missing to get my internet sharing working?
Thanks!

OK, on your iPhone you have four fields that need to completed for any type of WiFi networking to operate. The fields are (in order) the IP address of your device, the subnet mask for your network, the "router" IP address, and finally the DNS addresses.
I'm not sure what these numbers look like on an ad hoc network, but a typical router based network would look like:
Device IP: 192.168.1.x with x being between 2 and 255
Subnet mask: 255.255.255.0
"Router IP": 192.168.1.1
DNS: usually a pair of IP address separated by a comma. Sometimes this is supplied by the network you are conneccted to, other times you specify an address (like OpenDNS or Google's DNS service)
If your phone has an IP address of 169.x.x.x, it means that your ad hoc network is not supplying it with an IP address. Make sure that the DHCP box is checked (the ad hoc network will assign an IP address) or manually assign IP address.
To be honest with you, I'd go out and buy a basic N router (about $40 US), plug it in to your ethernet connection, and connect your devices to that. You get far better security as the router has a firewall and you can use WPA2-AES encryption on the wireless side - and it is easier to set up.

Can't Share Internet via Ethernet with Leopard

With Tiger I used to be able to share my Sprint USB Broadband connection with my Xbox 360, using a Airport Express which was connected through ethernet to the iMac. In Leopard it seems like their remove the internet sharing via ethernet option, which won't let my set up work. It lets me share internet comming from ethernet, but no the other way around. Any solutions?

Hi,
I need to better understand your set up connecting to the internet. Pls correct me if any of this is not true:
You have a USB modem connected to your iMac by USB cable
You have an Airport Express connected by Ethernet to your iMac
You want the iMac to pass the USB internet connection to Airport Express and have the XBox obtain internet from Airport Express?
In Tiger can you remember what you had selected for "Share your computer from"?

IPhone 3GS can't share internet connection with a windows 7 64 bit version?

I have an iPhone 3GS with the latest iOS installed, then the personal hotspot option is ON and it shares internet connection to a laptop with Windows 7, 32 bit version and with the latest version of itunes installled (10.6.1.7).
But when I connect this same iPhone to another laptop with Windows 7, 64 bit version with the latest version of itunes 64 bit, there is no internet sharing, no error, no signal of fails, it is just as if the hotspot option were OFF.
Its is posible to share internet from iPhone 3GS to a PC with Windows 7, 64 bit version?

Hey there @slee , welcome back
I would suggest trying the steps in this guide for the installation troubles you are having on your one specific Windows 7 computer.

You can also try disabling your firewall while you run the installation to see if that helps.
Let me know the results!

Extremely slow Internet over Airport, good speed with Ethernet

I've been using an airport extreme router (802.11n) for a while and recently I've noticed an incredible slow Internet over wifi. When I do a speed test it shows numbers like 200 kbps and I have a 10 mbps cable Internet connection. When I connect the ethernet from the modem it's perfect speed. Obviously Airport is slowing down my Internet connection. I tried resetting the Airport by pressing the reset button at the back, and it worked perfectly for a while. But after a few days it got back to slow Internet. Anybody have any idea?

I don't know if this will help anyone else, but I came across some changes (purely by experimentation) that may help. I hope so, at least...
I opened the Airport Utility and I swapped channels. The default is channel 6, but every other WiFi router defaults to this channel, too. I changed my Airport Extreme to use channel 3 (as well as my Airport Express), and now things are back to what I would have expected for an 802.11g connection.
I will offer the suggestion that those of you with the same Internet slow-down observed on their iMac G5's try swapping channels. If you have an expanded WiFi home network vis-a-vis an Airport Express, be sure to update it first before you update your Airport Extreme.
Best wishes and good luck!

Why my iPhone 3GS can't share internet with another iPod, iPhone or iPad with iOS 6.x?

Hi.
I am from Mexico, sorry from my 'english'.
I have an iPhone 3GS with iOS 6.1.3, i can share internet with USB and Bluetooth.
It's ok, but when want share, my iPhone 4S with iOS 6.1.3 doesn't detect the 3GS, and vice versa.
When i try connect with Bluetooth with a iPod Touch Fourth Generation with iOS 6.1.5, i can't too, they doesn't detect too.
When i try connect with Bluetooth with a iPod Touch Fifth Generation with iOS 7.0.4, it works!!
When i try connect with Bluetooth with a iPod Touch Third Generation with iOS 5.1.1, it works!!
¿What can i do? I can't connect with Bluetooth with whatever terminal with iOS 6.x.x

Your best bet is to switch phones with your carrier and get your 4S on the data account.
Otherwise, try resoring the iOS in your iPhone 3GS via iTunes.

Can't share internet (via ethernet) with 2 Mac Pros

I've got 2 Mac Pros, but only one cable from my cable modem. (I'm aware I could get a router, but I don't want to do that yet.) So I've got ethernet going from cable modem to Mac Pro 1 (MP1) into its ethernet 1 port and it works perfectly.
Now I'd like to use MP1's ethernet 2 port to share internet with MP2. I can't get it to work.
Settings: on MP1, in System Prefs > Sharing > Internet Sharing, I have it enabled, and set to "Share your connection from Ethernet 1 to computers using Ethernet 2"
On MP2, it's set to DHCP. But internet doesn't work on it.
I can use file sharing to connect from MP1 to MP2 (or vice versa) so the ethernet cable is good. I can transfer files back and forth. But if I launch Safari on MP2, it won't pull down any web pages.
Strange thing: on MP1, in System Prefs > Network, ethernet 1 has a green light and shows connected (that's OK). But ethernet 2 shows a yellow light, says "self-assigned IP", and configure IPv4 is set to "Using DHCP" and the IP address is 169.254.xxx.xx. I'm suspicious that this starts with 169, since I think that means it's not working. Also if I look on MP2, its IP address is 192.168.2.xx.
Can anyone help me get internet working on MP2?

Helpful, but still not working.
On the first Mac Pro (MP1, the one connected to the cable modem), Ethernet 1 is connected to the cable modem, and it has an IP of 192.168.2.100, subnet mask of 255.255.255.0. It works perfectly.
On the first Mac Pro if I go to the Ethernet 2 tab, I'm not sure what to fill in. You said not to use DHCP? So I tried Manually, giving the IP 192.168.2.102, subnet mask 255.255.255.0, and leaving router, DNS server, and search domains blank, as you suggested.
On the second Mac Pro (the "slave"), I set it to "Using DHCP" but (mysteriously) it assigns itself an IP address of 192.168.2.3. It does grab the subnet mask and router automatically. Communication between MP1 and MP2 works (I can log into one from the other), but internet does not. It's like it's partially working. I tried DHCP with manual IP, giving it the same IP (192.168.2.3) but then it says that IP is in use.
Did I do it right? On MP1, Ethernet 2, should I be configuring things manually? (I've tried DHCP too, and that doesn't work: MP1 shows an IP of 169.254.213.35 and MP2, set to DHCP, shows a different IP of 169.254.161.138.)
