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.

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.

Internet Sharing problem with Airport Extreme

I can connect to the Internet with my iMac running 10.4.11 fine. The problem is that I can't share the connection with my laptop. When I go to System Preferences and select Sharing/Internet, Airport doesn't appear anywhere as a connection option. I tried running Airport Utility and I got the message, "AirPort Utility was unable to find an Apple wireless devices".
This all started when, originally, my laptop could connect to the Internet, but was unable to connect with the iMac. In System Preferences/Network I got a message that says "Your network settings have been changed by another application" and the only way I can get out of it is to force-quit system Preferences.

Hi,
Must ask, if you have an AE, why do you wan't to go through Internet Sharing?
When I go to System Preferences and select Sharing/Internet, Airport doesn't appear anywhere as a connection option.
You mean as a to: or a From: option?

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.

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.

Remote App and Internet Sharing Problem

Ok so basically heres the setup we have, we have one of the recent iMacs, a Macbook, and 3 PC's, one running XP and the other 2 Vista. All of these computers are on a network together. All our music is on one of the Vista PC's, called "SERVER". This PC is connected to the speaker system, so is what we use for music.
Now I've been trying to use an iPod Touch we have (most recent firmware 2.2, and most recent Remote app version.) and the remote app to control the itunes on this PC. This is not an issue when the iPod is connected to the Wifi the router itself provides (its one of those wireless routers), but when I switch the Wifi the iPod is using to the Wifi provided by the iMac using internet sharing, it suddenly can't find the library anymore. Internet (safari) still works fine from the ipod when connected to this Wifi point.
My guess is that because the iMac using internet sharing seems to act more like a router than a wireless access point (allocating its own IP adresses ect..), the iPod thinks its on a different wireless network, and thus cant see the itunes library. Obviously the iMac is connected to the router directly by ethernet, if I hadnt mentioned that.
So, my question is, can I fix this ?
Is there any way to make the internet sharing mac behave like a wireless access point and not like a router ?
Help would be much appreciated.
Thankyou.

asuming you mean internet sharing as in you connect adhoc to 1 computer using wifi and the rest of the network is wired
problems is the middle name of adhoc wifi though cause everybody problems imho
and wifi routers are soo cheap most people don't bother
even if internet sharing is used remote app should still work if not connecting adhoc at least it's working for me right now
with a setup of many computers 1 wifi router
1 computer sharing internet using an usb 3g modem
remote app works with all my computers and my appletv

Lumia 710 signal and Internet sharing problem

I've been using Lumia 710 since 3 months. Even though the initial experience was good now I'm facing a serious signal problem with the phone. We recently moved to a high-rise building where the signal is weak inside the rooms. If the phone looses the signal it doesn't pick-up the signal even though network is available. This is causing a serious a trouble to me as I don't receive or make calls during the period. I either need to switch-off and switch-on again or I need to turn-on and turn-off flight mode for the phone to pick up the signal. Sometime even though the signal shows 3/4 bars I won't be able to make/receive the calls.
I'm also facing a issue with Internet sharing option. Even though devices are able to connect they are not able to use the internet/data from phone. I was using the same SIM with other phone of different make and it was working pretty fine. I rely a lot on internet sharing option and now I can't even swap my SIM with old phone as Lumia uses micro SIM.
Please let me know the solutions to both these issues.

That is not normal though. Bring your phone to your local Nokia Care Center and let them have a look at it.
Internet Sharing on Edge/G is not working very well, try and find a 3G connection (which is fast enough) and you will get a better experience.

Created Network and Internet Sharing Problems

Hello,
I created network with WEP password. I proceeded to turn on internet sharing.
All works great until the iMac goes to sleep.
Once it comes back on the network I created is missing and I have create it all over again.
The internet connection is through ethernet staring into the iMac.
Is there a way to get the iMac to stop forgetting the created network and leave the internet connection on? Even when it's sleeping.
Thanks in advance.

Hi there,
Is there a reason why you chose WEP? I ask because WEP is an encryption technology that has been cracked so if possible I"d suggest you use WPA or WPA2 encryption instead. Am I correct to assume you don't have a router and all the other computers connect to the internet through the imac? If you don't have a router I'd suggest you buy one, they are not much money and provide excellent protecton from the internet. A router will protect all the computers on your network behind its firewall and would no longer have to connect through the imac.
A couple of things to check:
Go to System Preferences>Network and highlight 'Wireless' on the left side. (Also, if you don't use Bluetooth or any other type of networking listed there delete them from the list leaving only Ethernet and Airport) Uncheck 'ask to join new networks'.
Then click on 'Advanced..' and under the Airport tab make sure only your network is listed in the 'Prefered Networks' window. Under that window check 'remember any network this computer has joined' and uncheck 'disconnect from wireless networks when logging out'.
That's the way I've got my computer set up and I've never lost a connection.

Hotspot and internet sharing problem

Hiiii.
I have purchasd Lumia 520...bt when I tried to connect it by using wifi hotspot it gives certain prblm...
. It says internet sharing is not currently available....plzzzz help......
cndn gettng worse without internet.....plzzz help

I've got similar problems but with my connection tethering doesn't even start:apn was filled in, I start 3G which gives me perfect data transfer H+ quality, wifi is swiched on, I start tethering, I get the tethering menu with lumia 720 name and #of connections =0, the "configuration" button though is GREY and not not active at all, and after 2secs the whole menu is left and the lumia goes back to the main system menu telling me " there's no data connection to be shared" and calls it a day... I tested the same SIM for tethering with exactly the same apn on my old lumia 610 running wp7.8: result is a perfect tethered internet connection, 3.5G speed. So I'm f.ck.d up with my wp8 lumia running Amber!
Can anyone out there in Nokia HQ tell me why a "better" product is performing with a lot more bugs! And this is a big one! I will consider the 720 for a short while if this isn't solved it goes out and will be replaced by an iOS product which tethers as it should.

10.7.1 update doesn't fix my internet sharing problem

I've updated my Macbook (late 2008) to 10.7.1 today. I'm disappointed to find that the internet sharing issue still exists. I can ping websites through it, but wget never work. Google.com is accessible while other sites don't load on my iPod touch and Palm Pre Plus. But it did work fine within seconds after internet sharing was started. And internet sharing on my iMac with 10.6.8 works perfectly.
I'm using PPPoE to connect to the internet. I guess there are some problems with MTU (maximum transmission unit).
Don't tell me to change wifi channel or set password, it doesn't help.

Internet sharing worked on 10.7 after doing 1 tweak, that is by changing my Computer Name in internet sharing to something else other than the default one... however after upgrading to 10.7.1, the upgrade would mess up with the same tweaks again. It brought my Computer Name to its default, however when I clicked on edit it would give the changed name... I noticed that it has something to do with the IP Address but in any case I did the following and it works again for me on 10.7.1:
1) Go to System Preferences>Sharing and click on Internet Sharing (don't 'tick' it yet!)
2) After upgrading to 10.7.1, the Computer Name displayed on the Internet Sharing Screen would revert to the original, i.e. YourName's MacBook Pro. However, upon click edit next to the space where you can enter your Computer Name, it would give the name I had given while I was on 10.7.
3) Now you just have to make sure that both names are identical (do not use the default name YourName's MacBook Pro). Please see snapshot below (yes, my Computer Name is 'Network-Error', so don't be surprised:))!
4) Once you have confirmed that both names are identical, you are set to go and you may 'tick' the Internet Sharing option
5) An arrow facing upwards will appear instead of the wireless icon on the top tray and your device such as an iPhone should connect without any issues (an IP address will be given).
Note: the other options that I have kept in the Wi-Fi Options tab are as follows:
1) Network Name: should be identical to the one you have entered above
2) Channel: 11
3) Security: 40-bit WEP
4) Password: I've entered a five-digit password that contains numbers
To confirm that its working for me, I've added a screenshot from my iPhone below:
It doesn't work for me. Thanks anyway.
