AirPort Internet Sharing

I am using MacBook Pro Snow Leopard, and I select Internet Sharing ON to AirPort so I can connect my Nokia phone to it. The problem is, everytime I set a password, my Nokia failed to connect to AirPort. It can only connect and use interent when no password is set.
Is there a way to see if there is anyone else trying to connect to AirPort and what they are accessing?

The Airport users hang out in the Airport forums.

Airport Internet Sharing Problem Mini - PC Laptop

Airport Internet Sharing Problem
My setup is:
Cable Modem -> Mac Mini --> PC Laptop
... with the connection between the mac mini and the PC laptop being the built-in mac mini airport using internet sharing.
Hi, I've been trying to set up Airport internet sharing with the mini, to no avail. It works off & on, but invariably the internet connections drop after about 10 minutes. The only way to get it started again, is to go into internet sharing, turn off internet sharing, then turn it on again. It will work for another 10 minutes or so (slow) after gong back to the PC laptop and reconnecting, then it chokes again.
I've tried the connection both with & without WEP, same behavior. I read somewhere that OS X only plays well with using Channel 1, so I tried that. No luck. Tried with and without Interference Robustness, no luck.
Tried with WEP on and using 40 bit hex keys using a "$" prepend in the mac as suggested on this web page:
http://www.macosxhints.com/article.php?story=20030803030354585
Same behavior, works for 10 minutes, then it chokes again.
Tried with & without the firewall.
Yes, personal web sharing is on.
The PC laptop works fine with any number of other wireless routers out & about town, at my girlfriend's house, so forth.
Any chance I have a bum mac mini wireless card or antennae or something? The reception strength on the PC laptop is good.
Just don't know what to make of it. So stupid, it seems like something pretty basic that ought to work.
Yeah yeah tell me to get a wireless router, but I'm not going to do that, that's one major reason I bought the mini in the first place and it would be nice if it worked as advertised.
Any other suggestions?

Works better now...
this is me again. A week ago or so, I noticed there was an automatic update to the wireless on the mac mini.
Since then the performance is much improved. My PC laptop connection to the mac mini no longer drops spontaneously.
Much improved! Thank you very much!
Yes, on occasion, when I leave and then come back to use the wireless, the laptop will not reconnect after multiple attempts; I have to turn of internet sharing and flick it back on again, but then it works all evening fore hours and hours straight with no problems.
Thanks Apple! It's usable now!

IMac & Snow Leopard - Airport internet sharing: WEP only?

Hello guys, happy owner of a 24 inche iMac.
Found out I can turn my iMac into a wireless access point by enabling airport internet sharing (system preferences > Sharing > Internet). That's nice because in my setup that would be better than paying for a wireless router and having even more cables and ac adapters cluttering up the place.
But, the airport settings for internet sharing only allows for WEP. No WPA??? That's a bit surprising, and a bit disappointing. I'd rather leave this sharing enabled all the time and I'm not thrilled about using WEP (everybody says it's pretty unsafe)like that.
Is there a way around that?

I a in a similar situation. I am sharing my cable/ethernet connection with a powerbook & an iphone quite happily. But my niece's pc will not connect. It insists on WPA, stating that the WEP is not secure enough, yet it quite happily connects if I remove the pass key altogether.
Can anyone help?
The pc does suggest performing a manual connection but I cannot find the details (ip address etc) in my iMac

Does Airport Internet Sharing Support WIFI Mode G?

I am trying to connect a Nokia N810 Internet Tablet to the Internet via Internet Sharing. The N810 only supports B and G mode WIFI. I can't get a connection. Does Airport Internet Sharing Support WIFI Mode G? Do I have to configure for this?
Thanks

I am trying to connect a Nokia N810 Internet Tablet to the Internet via Internet Sharing. The N810 only supports B and G mode WIFI. I can't get a connection. Does Airport Internet Sharing Support WIFI Mode G?
Yes.
I've used my 802.11b/g/n capable MacBook to share an ethernet connection with my 802.11g ONLY iPod Touch.
Does the N810 see the network?
Does any other WiFi capable device in your home see the Internet Sharing SSID?
Did you give your Internet Sharing a password? Internet Sharing uses WEP for encryption, and the rules for creating the WEP Hex key from a text string password are different for Macs vs everyother WiFi device in the world. 1st try no password. If that works, then move on to using a simple 5 character password for 40/64 bit WEP, or a 13 simple password for 104/128 bit WEP.

Airport Internet Sharing and Double Nat Issue on the road

The Airport express is a very handy little piece of hardware that is particularly easy to pack in a luggage and carry along for those of us that are spending lots of time out of the office and home.
So here is the scenario when I travel and check in into an overseas hotel: I got two iphones, one local network, one my home network, and a Mac Book Pro, and soon, [when it finally ships], an iPad.
That makes it at least 3 MAC addresses in one room, and if i have any visiting colleagues to pack up a presentation, I will have more.
Usually hotels in Asia are well equipped with ethernet points in every room. The problem comes when I want to allow all my gears to connect to the internet.
I can use the Mac Book to share its ethernet connection while tethered to the plug, which not only turns it into an unlikely desktop, but also do not champion stability when it goes in stand by or sleeps and at times it even mixes up which is the access point to the net. Therefore this does not seem to be the best solution.
I can put the AE in bridge mode and plug it straight to the ethernet. But most hotels internet access are designed to charge per MAC address, so every time the router assigns via DHCP an IP to one of my gears it requires to accept new charges for that gear, even if they are all in the same room. This definitely does not seem right either.
Now if I configure the AE to share a public IP address and force it to ignore the double NAT warning, the AE light turns green but the internet sharing does not seem to work at all.
My two questions are:
1) Why can't the AE be configured like the Mac Book to have a simple "Internet Sharing" protocol that will be always live and not going to sleep or stand by like the laptop [As the AE is design to be always online as a wireless connection].
2) is there any way to make that "Share a public IP - *** double NAT" work?
Any feedback is welcome.
Thanks. M

Hi Bob,
thanks for your reply. Yes the only way to work it out on a typical hotel set up is to adopt the bridge mode and sometime the do waive your extra logs in. But I am not always so lucky and I often need to come up with less optimal solution.
This is a bit disappointing when you a have a AE in your luggage and you can't use it properly.
Yet my Mac can work the problem out effortlessly by just "Sharing a internet connection" with the only major limitation of being physically connected to the Ethernet cable.
Why can't the Airport Express do the same thing? Basically the AE could share the internet connection like the Mac Book, i guess introducing a secondary layer of NAT after the Hotel modem/router NAT setup [which is what the MAC Book is doing].
If AE can't do that at all then I guess soon we will just end up shelving it.
I wonder if this is an actual hardware limitation, MAC Book can wire TCP/IP flow to different sources on a double nat and AE can't, or this is just a software limitation and Apple could fix it with a firmware upgrade.
Any thoughts on this?

Can't Use Safari with AirPort Internet Sharing Switched on

Happy New Year All (for tomorrow).
Just got an IPod Touch and a brand spanking new G5 iMac with AirPort built in (and what a beautiful machine it is...). I have switched on Internet Sharing i.e. "Internet Sharing: On (Sharing your Built-in Ethernet connection)". At the moment, I'm taking my ADSL into the iMac via a DSL Modem Router and then ethernet cable into the back of the iMac (until I get a wireless modem router). However, my iPod touch doesn't seem to be able to connect to share the internet connection over AirPort. A couple of nights ago, it connected and worked fine for about ten minutes then gave up. I haven't been able to get it to work since.
The Airport Symbol in the status bar (top right of screen) shows an arrow pointing upwards (I assume this means internet sharing is "On"). I'm running 10.5.1 And on another note, my wife's iPhone has the same problems.
If I get a wireless modem router, will this problem go away?

I've never messed with interne sharing. However, reading your post would seem to give a clue: Internet Sharing: On (Sharing your Built-in Ethernet connection). It sounds as if it's only sharing the ethernet (cabled)connection, not the Airport (WiFi) connection. I'm not at a Mac right now so I don't know if there's a way to change that setting. Also, if I recall correctly, people have reported problems sharing an Internet connection with a Mac. I don't remember the details as it wasn't an issue for me.
I have my DSL plugged into an Airport Extreme Base station. Service is distributed both by Ethernet cable and by wireless from there. The Touch connects beautifully.

Windows ethernet - MBP Airport internet sharing

Hmmm i am using my airport on my MBP fine.
i want to share my internet to a windoze pc via ethernet.
it says that ethernet is active but your computer doesnt have an IP address and cannot connect to the intermet.
on the PC it says something along those lines...
whats that about?? any ideas?

Have you turned on Internet Sharing in the Sharing System Preference?

Timeout using Airport Internet Sharing

Posted this under the MacBook Forum, too. None of these Airport forums look exactly correct, so I'm sorry if this is the wrong place, but it's the best I could find.
I've had a Mac Mini for a couple of months now, and have just recently added a Mac Book. The Mini is connected to the Internet through the ethernet port and a cable modem. I decided to share the Internet connection with the MacBook using Airport. Both computers are running Mac OS 10.4.7
I set up the connection (with WEP and a password) easily enough, and it works, for about 10 to 15 minutes at a time. Then the MacBook stops passing any data over the Internet. In the Network tab of the System Preferences, it will still show that it is connected to my other computer, but the browser stops seeing web pages, and other Internet apps timeout also. I've also tried opening terminal.app and pinging sites. Nothing. The Mini continues to work fine, so my cable connection isn't dropping. The only thing I've found that will let me start using the Airport connection again is to go to the sharing preferences on the Mini, turn sharing off, start it up again, and then log in again from the Mac Book.
My first thought was that it might be some sort of power saver setting on the laptop. When I use a public WiFi access point with the Mac Book, however, I don't get these timeouts, but can keep on using the connection for as long as I like. So it seems that the Mini will just stop sending data over the AirPort connection after a while. I'd kind of like to make this work, since, if it does, there is no real need to buy a separate AirPort base station.

This is happening to me as well. I travel for work and when I am at home, I simply have to reconnect (put in my password, etc.) and I am on again. Not too much of a hassle.
But, in hotels, the wireless feels like dial-up. It is very slow. The connection resets or is timed out and the Airport signal still shows at full strength.
I even used an ethernet "bridge"? and it did not help.
The ISP says they are getting a signal to and from my computer and that nothing is wrong with the system.
I run Diagnostics and it either says it is working properly or asks if I typed ww.apple.com instead of www.apple.com
I am going to call Apple Care and see what can be done myself. I'll let you know what I find out.
(I actually just had to come back to this and cut/copy because the connection was lost as I wrote!)

Where has Airport "Internet Sharing" gone.

It used to be easy to set up Tiger to allow others to share your internet connection over Airport.
In 10.5.2 this feature seems to be absent, anyone know if there is some other way to set it up now?

TC as a brigdge to extend internet sharing from Imac

Hello, can somebody give me a hand on a proper config for time capsule + Imac.
My setup is: 3G Huawei modem/router - wi-fi (g) network - Imac Airport- internet sharing (airport to ethernet) - ethernet cable to TC WAN port (TC in a bridge mode) - time capsule wi-fi (n) network.
All seems to be functioning well, and I can access second (n) network from Ipad, Iphone, Apple TV2 etc.
The final goal of this setup is to block with MAC filter on Huawei router I-net access for Apple TV while keeping an access for Apple TV to my libpary (photo/music) on Imac. The reason to do so is very simple - I have very limited data plan/speed from internet provider and I don't need neither youtube or anything from internet to hungry Apple TV (automaticaly eating lot's of data even refreshing covers etc and there is no way to turn it off even with parential control) I've puted MAC address in Huawei filter but Apple TV still accessing I-net. Looks like it using TC router and I can't turn it off to force using Huawei router. Any thought? Thank you

Well, if there's anyone else with this problem, I have an update:
1. After some reboots, for reasons unknown, the G5 started to connect.
2. However, it would only connect to an unencrypted network from the iMac. When I tried to change to an encrypted network, it wouldn't connect. Nor would it work when I switched back to an unencrypted one!
3. I then tried the following, from another site:
Start Internet Sharing if it's not already running.
In Terminal, type cp /etc/bootpd.plist /tmp/bootpd.plist
Stop Internet Sharing.
Open "open -e /tmp/bootpd.plist" for editing using TextEdit or whatever.
Locate this section of the file, near the end:
<key>replythresholdseconds</key>
<integer>4</integer>
Change the value 4 to 0.
In Terminal, type sudo cp /tmp/bootpd.plist /etc
Start Internet Sharing.
If you want to, check that your change to /etc/bootpd.plist hasn't been reverted.
Source - Following 10.5 Steps
http://www.macosxhints.com/article.p...ery=xbox%2B360
4. It worked. Now the G5 will connect to an encrypted Internet Sharing network from the iMac. Not only that, my iPad, which previously would not connect to an encrypted network from the iMac, will do so as well.
Hope no one else is as frustrated as I was!

Can't create airport/wifi internet-sharing network with other laptop

I have an iBook running Tiger 10.4.11 connected to the net with ethernet. The internet connection comes through a radio antenna which acts like a router to which I don't have access.
I want to share my internet connection, and to be able to transfer files, between the iBook and another laptop. I've tried it with two - one running Fedora 11 (mine) and one running Windows XP, and have the same problems with both.
I turn wifi on on the ibook and linux laptop. I turn on internet sharing from built-in ethernet to airport in System Preferences. First I try it with no encryption. 'Other settings may interfere with internet sharing' shows up; it tells me to enable Personal Web Sharing, which I do. When I click start Little Snitch tells me natd wants to connect to 10.0.2.1 (presumably the router in the antenna), which I allow. I try to connect with the linux laptop and it tries then disconnects.
1) isn't personal web sharing for serving web pages? — why is it necessary here at all?
2) what am I doing wrong in making my network work?
If I enable encryption using WEP, the other password asks me for authenticication, I put in the password, and it then tells me the network has been disconnected.
3) is WEP the best encryption I can use from Tiger?
4) I think the problem's with Tiger (both laptops can connect to other wifi networks not set up by me). Is there a piece of free software I can use to share the connection instead of the built-in one?
I can't make a functional network in reverse either (i.e. setting it up on the other laptop and trying to connect wirelessly with the ibook).
What I am trying to do is precisely this (http://my.safaribooksonline.com/0596009135/runmacx2-CHP-11-SECT-13) — it just doesn't work.

When I click start Little Snitch tells me natd wants to connect to 10.0.2.1 (presumably the router in the antenna), which I allow. I try to connect with the linux laptop and it tries then disconnects.
Back on that part, at that Point the Mac is a NATD Router, don't try to connect to the other computers.
On the Mac, with Internet Sharing enabled, open NetInfo Manager in Applications>Utilities.
From there on out, it's a bit foggy, but iirc Config>DHCP>Subnets><the subnet>, then down where it says com.apple.nat... what does it report for IPs?
If it were say 10.43.29.1 then the others trying to join should have that as a Router/Gateway, and then 10.43.29.2, 10.43.29.3, etc. as IPs.
Apple says you can't set it Manually, but I've had it work a couple of times.

Airport Roaming Network and Internet Sharing

Dear Esteemed Experts (Tesserax et. al):
Thanks to you, I have successfully set up TC and 2 Airport Express N in a roaming network (plugged to Ethernet but using the same name and protocol) using 802.11n (b/g compatible) radio mode. It's working well, except a few blind spots to cover.
If I want to add an old b/g-only Airport Express or Netgear Access Point (WG602) to this roaming network (plugging them into Ethernet outlet), will this slow down the N network?
Also, can I turn on Internet Sharing on my iMac (with N capability) and make it to join the Roaming Netowrk? If so, can I manage it through Airport Utility?
Thanks
Aghoo

If I want to add an old b/g-only Airport Express or Netgear Access Point (WG602) to this roaming network (plugging them into Ethernet outlet), will this slow down the N network?
If it is connected via Ethernet it will have no direct affect on the performance of the 802.11n network.
lso, can I turn on Internet Sharing on my iMac (with N capability) and make it to join the Roaming Netowrk?
Internet sharing has nothing to do with joining a wireless network. If you want your iMac to join the wireless network, just go to the AirPort menu and select the network that you want to join.
If so, can I manage it through Airport Utility?
AirPort Utility is only for managing Apple's base stations.

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.

Airport and internet sharing turns off by itself

Hi everyone, I have an imac that I purchased earlier this year, and I use internet sharing to get internet for my ipod touch. Until a few months ago, this worked fine but now airport and internet sharing turn off every time I restart the computer and I have to turn both back on every time. Is anyone else experiencing this problem or know hot to fix it?

Hi and Welcome to Apple Discussions...
Download and install the v10.5.8 combo update available here.
http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
One of the "fixes" includes: - compatibility and reliability issues when joining AirPort networks.
After the installation, repair disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.

Airport Express and Internet sharing.

I have been told that I can share the internet connection, wireless, of a Mac that is connected to the internet via the ethernet port by using Airport Express. I am at a loss on how to create this environment. Can anyone help? I am trying to create a wireless network to use my itouch through internet sharing.

Please see this Apple Tech Help page.
