Enabling 'Internet Sharing' disables my internet connection

Hi all, my desktop computer (iMac 27") is hooked up to the internet via ethernet cable/modem. Very simple configuration. I normally share the internet connection (password protected) that my other devices access via wifi.
For months this has been working just fine. today I've been having connectivity issues. I worked with my cable company to determine the issue. what finally solved it was disabling wifi, shutting down the modem & computer. Then boot the modem, afterwards boot the computer.
This worked great, I saw everything working in Network Diagnostics...
Then, I re-enabled Internet Sharing, with the same settings I've used for months, and I saw the connection disappear immediately in Network Diagnostics (Ethernet & Network Settings were green, all else red).
Rebooting the router didn't work. Restarting the computer with with wifi enabled didn't work. I had to disable wifi, turn off everything, boot modem, boot computer to get it to work again. Any time afterwards, where I enabled Internet Sharing the connection would break again.
Please help! Thanks!

I guess he meant to give this link :
http://docs.info.apple.com/article.html?path=ServerAdmin/10.4/en/c1gs9.html
Also setup DNS in the server and use that for LAN clients or you probably will have to change firewall settings to allow the use of a public DNS to-from LAN.

Screen-Sharing and Internet-Sharing via same network connection

Hello out there,
I'm using a TiBook (G4 867MHz) and a MacBook Pro 17". They are connected via a WLAN-router. Additionally the MBP is connected to the internet via an UMTS-connection established with a Merlin 870XU type PC-card.
Network is working fine, including screen-sharing. Also the internet connection on MBP works without error. But if I activate Internet-Sharing via WLAN to get my TiBook connected to the internet, the MBP connection to the WLAN is cut off.
Can somebody tell me what's going wrong and how to solve it?

Lumia 920 - internet sharing doesn't work: Connect...

Hello all,
I'm experiencing a serious problem with the lumia 920. It seems impossible to share my internet connection. Something I normally use for several hours a day. If this problem can't be fixed soon, ill be forced to swithc back to iphone or htc.
Problem description:
When turning "internet sharing" on:
Connection not shared - There is no cellular data connection to share right now. Check your cellular settings and signal, and try again.
Important remarks
Belgium - cellular provider is Mobistar
I can browse, sync email, etc over the provider's network ans send and receive MMS.
Provider does not block internet sharing. Have always used this.
OS Version 8.0.10211.204
Firmware revision: 1232.5957.1308.0002
Access point :
Nokia Access Point version:3.4.1.7 - db 2.0.0.100 - lib 1.2.0.7
The default access point provided in the Nokia Access Point app does not work: can't even browse.
Using a manually added APN:
Data type (default / LTE) tried both. Everything keeps working - except internet sharing...
APN pro.web.be (for professional subscribers)
MMS APN mms.be
MMSC address: https://mmsc.mobistar.be
What have i tried to remedy the situatiuon?
updated the Nokia Access Point app
changed language to spanisch using OTA update (silly, but read on a forum this might help)
soft reset of the phone (often!)
deleted the manually created access point
Hard reset of my phone
I'm interested, of course, in any tips to solve this serieus bug / issue / problem.
(my best guess is that Nokia tries to help their customers with the Access point app, but fails to do so).
Please, if any of you experience the same problem please respond to this post so we can get an idea about how big of a problem this is.

Hi,
I had the same problem. But I let it go after weeks of corresponding with Mobistar.
Yesterday I went to a Mobistar shop, the guy tried lots of thing I already tried (different apn's, ...).
Then he told me the it's a problem with business clients. They have to use the apn web.pro.be, where internet sharing doesn't work (he doesn't know why).
But, that if I call to Mobistar and ask to activate apn mworld.be on my telephone number, it should work.
Today I called Mobistar Business (you can find the helpdesk number on your invoices), asked to activate mworld.be to have internet sharing access on a windows phone.
Half an hour later, using mworld.be as apn i have internet access, and I can share my internet connection.
regards,
Stijn

Can I use internet sharing to give internet to my Apple TV through my Macbook and use Airplay on the same computer at the same time?

So I am using internet sharing from my Macbook to my Apple TV. The router providing internet to my Macbook has an ip address that looks like 192.168.0.x. Since the internet sharing feature assigns an ip address that looks like 192.168.2.x to my Apple TV, the Macbook is unable to see the Apple TV ("different" networks). Is there a way around this so I can share internet and still be able to use Airplay between the two?
BTW I am using a Macbook Pro Retina 15'' (late 2013) on Mavericks 10.9.1 and Apple TV 3.
Thanks.

Why are you tyring to spilt your connection though the MBP? Why don't you just connect them both to the router as they are meant to be setup?

What is the "Internet sharing disabled" message I have been getting the past two weeks?

I have never had this before. I disable the app but it keeps returning. I don't notice it actually affects anything, it is just annoying to get this message several times a day. I can't find any way to disable this or turn if off.

ginalynn,
Thank you for reaching out to us. I am sorry that you have been having issues with your device recently. What it sounds like is that you have your Mobile Hotspot enabled. When you pull down your top bar do you see anything referring to that? To check you can also go to settings>data>mobile hotspot. Make sure that is turned off. If not does it say anything else when the message pops us. Please fill us in.
Thank you,

Windows 7 wont connect to Lion Internet Sharing via Wifi

I have a 2011 Macbook Pro 15" with i7. I know the internet sharing feature works, because I used the wifi internet sharing with a Macbook Air and that worked fine. But when I try to connect from a Windows 7 Ultimate laptop, the connection cannot be established. I tried:
Changing the Wireless Name
Changing the encryption key
Tried no encryption key
Rebooted
Am I missing someting? Am I correct to assume that the built in internet sharing allows you to connect your devices to macbook pro as a router? I appreciate your assistance, thanks!

Same here.
I have all my machines (rather HAD) connected to the internet via a shared single connection through a 3G dongle (welcome to the countryside). I made the mistake of upgrading my machine to Lion only to realise a couple of days later that all the other machines had been starved of internet access.
Now only my main machine has access, even though according to all of my thousands worth of apple gear the green lights are on and all is ok. The Airport extreme says it's connected, its lying. The Timecapsule says its connected, its lying. The Mac mini says its connected, its actually admits there is a problem when you run the network diagnostics. Same for our macbook pro. At least the Windows machine says it's connected but no internet.
This is pathetic as apple have know there was an issue since june last year. Once more I get the feeliing Apple couldn't give a fiddlers'. Most likely greedily eyeing the forthcoming cash bonanza from the ipad 3.

IPhone - OSX 10.5.6 internet sharing via wifi has packet loss

I try to access the web on the iPhone (for testing purposes) via the bult-in internet sharing capability of my MacBookPro via WiFi. I get very slow connections and high packet loss on distances of less than a foot.
If I activate Internet sharing (eth0 - AirPort) I have packet loss of up to 80% on a Ping to the iPhone. This results in an unusable connection. In this case the iPhone gets a DHCP address from the DSL box (10.0.2.2). Pay attention to the HUGE standard deviation of the packets in case of the internet sharing!!
If anyone has config hints, I appreciate that very much. Does anyone know how to bridge en0 to Airport with WEP enabled?
Internet sharing activated:
--- 10.0.2.2 ping statistics ---
202 packets transmitted, 150 packets received, 25% packet loss
round-trip min/avg/max/stddev = 18.312/1768.538/8198.289/2201.202 ms
If I set up a Computer-Computer network with a WEP password I get no packet loss, but of course I cannot access the internet that way because there is no way in preferences to bridge the networks.
--- 169.254.246.154 ping statistics ---
443 packets transmitted, 442 packets received, 0% packet loss
round-trip min/avg/max/stddev = 1.441/1.983/57.068/2.691 ms

I accidentally found a workaround:
1. Activate internet sharing
2. Goto network preferences and use AirPort: "Create network ..."
3. Check require Password and create a C2C network
4. The Airport Icon changes from the up-arrow to the computer icon
5. Connect with the iPhone.
Packet loss is gone and sharing works fine.
BIG BUG: Procedure has to be repeated every time AirPort is turned on/off, as Internet Sharing disables/resets the airport setup!

Internet Sharing Drops

Hi,
I posted a few weeks ago about how frustrated I am with Leopard developers for doing away with the ability to open/close ports on the firewall. The only option since then is just disabling the firewall completely.
Now I have another problem. I connect to the internet (on my macbook) via wireless, and share that connection to a PC via ethernet. Occasionally I connect more than one PC so I share it via ethernet to a 5-port Hub (to which I connect the PC's). I used to be able to switch out the ethernet cable and the connection would resume, but now in Leopard, it doesn't. I am forced to go into Internet Sharing, disable it, and enable it again for the sharing to be re-established.
Is there anyway around this? I didn't have this problem in Tiger. Under Tiger I would be able to swap the ethernet cable and the sharing would resume automatically with no issues.
Thank you,
Frank

Internet sharing -airport- reverts to client

I am using airport to share my ethernet internet connection with my iPhone and iPad.
I configure this by going to:
system preferences > sharing > internet sharing > share my ethernet connection using airport. a start sharing window appears and after selecting this, the airport "pie slice" icon shows an up arrow and sharing is enabled. (I have set up a WEP protected AP in network).
After a varying number of shut down - start ups, airport reverts to a client looking for an AP.
I go into sharing and de-select internet sharing, re-select internet sharing, at which point the "start sharing" window comes up, I select start, lock the sharing window, then the airport icon stops showing bars, becomes an up arrow and sharing works,
When it reverts to a client, the next time I open sharing the lock is open (after I have locked it before closing). Why is it unlocked?
How can I keep this configuration permanent?

Secure Internet Sharing Macbook to iPhone 3GS in Mountain Lion

Hi there!
Trying to set-up a secure internet sharing from Macbook Air (Mountain Lion 10.8.2) to iPhone 3GS (update 6.0) via USB Dongle (Orange). The unsecure connection works properly, but thats not an option during my stay in Africa... Somehow the WPA2 personal security (which is the only option in the sharing panel) disables any data transfers. Connection is still present but no data is transfered.
- File Sharing is ON and also with Firewall OFF it won't receive ana data.
- No preferences in the Dongle panel available to allow internet sharing or whatsoever.
- In Internet Sharing panel (system preferences) connection is shared from MF192 (Dongle) using Wi-Fi port.
Someone any suggestions?
Regards!
Anthony

Might have found a related issue.
The Dongle creates several 'identical named' connections (MF192) in network overview...
Is there a way to prevent this?

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

VPN and Internet Sharing

I am running OS 10.5.8 on an iMac. I have the mac connected to the Belkin N1 Vision router (new). I have networked my xBox to the Mac via ethernet connection, and I have internet sharing of the AirPort on and the xBox connects to xBox Live just fine. When I attempt to connect to the VPN server, it will not. I turn off internet sharing and I can connect to the VPN server. Then when I try to turn on internet sharing again, I lose internet connection all together. Can anyone help?

Something else to consider.
If you don't do anything the default configuration of the VPN Server in Mac OS X 10.6 Server is to route all the users traffic including traffic for sites on the Internet via the Mac OS X Server. If your happy enough for only the traffic that needs to reach your internal LAN to go via the VPN Server and to let the (remote) users Internet traffic go via their own Internet link instead of the office VPN, then you need to add at least one rule in the VPN Server.
Launch Server Admin
Click on the VPN service
Click on Settings at the top
Click on the Client Information tab
In the big box at the bottom add a rule to route to your office LAN and mark it as type Private.
See page 151 of the Mac OS X 10.6 Server "Network Services Admin v10.6" PDF manual.

Port Forwarding and Internet Sharing

Hey all,
I have a wireless network set up through a Time Capsule. My iBook is connected to this network via Airport. In addition, I have a computer with no wireless connected to my laptop via Ethernet. I have my System Preferences set up to Share Internet with Built-In Ethernet. The problem is this. I want to use the second computer (which accesses the Internet fine) as a server. The Airport does not recognize the second computer as a Client, but does see the iBook. I believe I need to Forward Ports to the iBook (local IP: 10.0.1.5) and then forward them again with the iBook to the other computer which has the local IP 196.168.2.2.
Is my thinking right in this? How would I need to configure this to make it work as I've explained?
If I'm unclear I can clarify.
Thanks,
Daniel

Hi Daniel,
I think the problem is, is that the Internet Sharing isa pass through connection.
Try this, in Network>Show:>Network Port Configurations, duplicate the Airport interface, make sure the on used for internet is dragged to the top of the list, then Manually configure if need be, the second one to join the local Network.

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!

Internet Sharing service may cause iChat problems

Here are some good news: After months of frustration I finally found the cause for my iChat audio/video connection problems.
The symptoms were as follows:
When my MacBook Pro was connected to the wireless router (Time Capsule) via AirPort, I wasn't able to establish an audio or video connection. When I tried for example to connect to one of Apple's test accounts appleu3test01, appleu3test02 or appleu3test03, I always ended up with the famous Errors 7 or 8.
However, if I connected my computer to the Time Capsule via Ethernet (LAN) cable directly, the iChat connection worked.
So, why didn't it work via AirPort?
It turned out that the reason for my problem was the activated Internet Sharing service (System Preferences > Sharing > Internet Sharing). As soon as I deactivated Internet Sharing, iChat audio/video connections via AirPort worked like a charm.
Interestingly, after switching Internet Sharing back on it still worked until I set my computer to sleep mode. After waking up again with Internet Sharing still activated it no longer worked.
I have now permanently deactivated Internet Sharing and everything is fine.
Hope this helps others to solve their iChat connection problem.

If iChat can't do all or part of what it is supposed to do with Internet Sharing on, WHY DOESN'T EITHER THE OS OR ICHAT SAY SO? I would be nice if the problem were fixed (although it looks like the problem has been open for years), but in the meantime, it would be nice for the uninitiated to be given a clue regarding the non-obvious.
"There was a communication error during your Chat. Did not receive a response from ..."
There sure was!
