Internet Sharing Cuts off

I bought a mac mini a month or so ago (Leopard in the box but not pre-installed) to use as a media center and as a wireless router through internet sharing, the latter being a job my G5 used to do. Unfortunately, though my macbook connects to the network without problem, the macbook loses its internet connection usually after a couple of hours and I have to turn airport off and on on the mac mini in order to restore internet access on the macbook. I've looked around and heard of some airport issues with both Leopard and the Mac Mini, but haven't seen any solutions to this particular problem.

Positive. As I said this machine is also used as a media center, and it has happened on several occasions while I was watching a video. I realize it is possible this is a Leopard issue, but I saw one report on another forum of someone else's mac mini with the same problem running Tiger, so I put this thread here.

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.

10.6: Internet Sharing turns off after restart

I use Internet Sharing on my iMac to share the Ethernet connection from my computer wirelessly to my iPod touch. In Leopard, Internet Sharing would turn off after a restart. Snow Leopard fixed the problem for a while, but now it's acting up again. Any help?

Using MacOS X 10.6.2 I have the same problem.
My network configuration is just the other way around (wireless Internet and Ethernet LAN).
Looking this up in Google first, I came across this older support link of Mac OS X 10.2:
http://support.apple.com/kb/TA21168?viewlocale=en_US
The solution provided there is not really helping though.
However, it appears that this is a recurring issue Apple is struggling already longer with. Hope they straighten that out at one point.

Why does my Internet sharing turn off daily?

Why does internet sharing keep turning off?

Are the Airport bars still black & showing good signal when it gets lost?
Could there be another Network nearby on the same channel?
Any Microwave sources like TVs, Cell Phones, Ovens around?
Does the one providing Internet remain connect to the Internet when this happens?
Is the Ethernet Interface on the Mac that connects to the Internet dragged to the top of System Preferences>Network>Show:>Network Port Configurations, with Airport below it?

Internet constantly cuts off

Internet connection constantly cuts off. I go to wireless network connections and click on connect and it usually connects in a few seconds but then it will disconnect again - sometimes in just a couple of minutes. Comcast came out and changed the modem about 6 months ago and it was better (not cutting off as much). The last few weeks it is worse than before.

We have been having this same issue for over a year. I've talked to tech support, they've sent someone out. All they have me do is cycle the modem over, and over again. It's getting really frustrating. My kids do cyber school and it's interfering with their school, because they are constantly being kicked from their online classes, can't submit work, etc. They sent us a new modem last Thursday, and that did not help. It seems as if the problem has gotten worse. And to top it all off, now the printer won't even connect to the network. So now the kids can't even print out work!

Internet connection cuts off after accessing GraceNote CDDB

This is for everyone how has the same problem!
After several times being in situation my internet connection (broadband cable) has been cut off after accessing GraceNote CDDB, and after several times I had to either restart or shut down my Power Book in order to access GraceNote CDDB again for each CD I wanted to put in my iTunes Music Folder, and after I checked all feedbacks and discussions regarding this matter - I did find The Solution - finaly!
You just have to uncheck Automatic access to GraceNote CDDB in iTunes Preferences (Importing) and to do it from drop-down menu manualy - and everything will work in perfect order!

I just turned the IPV6 off, I previously tried restarting safari and the computer itself (im not sure which you were referring to) but hopefully turning the IPV6 to off resolved the problem. Thanks so muchfor your help, I think you got it =). If you dont mind me asking what exactly did that do that fixed it though?

Why does Internet Sharing Turn off when shut down/restart ?

I've have had my Mac for a few months now and it has gone beyond my expentation it was defenatly a good buy . I was wondering if there is a way to keep Internet sharing on when I shutdown or restart my Macit would stop working. Ive went to bestbuy and tried this out in other macs and the same thing happened when I restart or shut it. Internet sharing would say it is enabled in preferences, but it no longer has the arrow point up. Apple could you please fix this on your next update I use this as a wireless router and it performes well except when I have to uncheck the box enable it again . Thank you

Your computer has to be ON to be able to use the Internet Sharing settings....

Keeping Internet Sharing connections off Bonjour subnet

Hi,
I have my Mac Mini connected to my home lan via ethernet. I have set its Airport for Internet Sharing. Despite connections to the Airport being on a different subnet than my lan, any device using that Internet Sharing connected can "see" and access any Bonjour services (like Screen Sharing or AFP for example) on the lan.
Now I understand that those Internet Sharing connections connect to the router via NAT provided through my Airport on the Mini. But what I'd like to do is use ipfw or whatever to prevent the Internet Sharing subnet from accessing any IP on the lan with the exception of the router itself. With iptables I could probably figure this out (or get close), but I am not familiar with ipfw. Can anyone help me with setting up ipfw to do this?
Thanks,
Doug

I'm no expert but usually the router lets you share one ip address (assigned by your ISP) between several computers on an internal network and the computers can each connect via the router - they don't need to connect to each other. For example, I've got a set up with two computers (one is mine, one is my parents') and two airport base stations. One of the base stations acts as a router (the other just boosts the range so the signal is stronger upstairs) and it distributes internal ips between the other base station and the two computers. We share the internet connexion but neither computer is set up to share its own internet connexion.
So if you're asking what I think you're asking, I don't think you need to enable internet connexion sharing at all - you could just have the computers connect via the router. The only reason I can think not to do this would be if maybe the router doesn't allow wireless connexions and you needed to connect one of the computers using this method. Otherwise, I'd think you'd just connect both through the router.
If that doesn't help, it is probably because I have no idea what I'm talking about - or, rather, very little idea which is worse because it means sometimes I think I understand something a little bit!

My wireless internet keeps cutting off?

I will be browsing the net for sometime, then after maybe like an hour , the wireless net starts to give trouble. I know the router is working because it works on my HP laptop and cell phone. It would show it has full wireless bars but firefox or safari would just not display any webpages. While i'm connected to Ichat and Msn they would sign out and it still shows connected to the internet. My macbook is only 2 weeks old. I would really love your help thnkx.

WRT54GS UPnP Cuts off Internet Access

Hello, everyone! Having had an Apple TV for about a year and just recently getting a Roku, I've noticed a strange issue. Whenever I use UPnP to locally stream video, all access to the internet is cut off and stays off until I unplug the router and plug it back in. The local network still works fine, so streaming continues (and works very well), but there's no access to the outside. Is there something I can do to fix this; is this a case of a broken router or bad internet service?
Solved!
Go to Solution.

Another common Media Streaming Server is DLNA. On a Windows Computer this is enabled through Windows Media Player and your devices capable of DLNA will be able to see your Windows user folders like Pictures, Videos and Music.

Internet cuts off when using the phone

The last few days, as soon as the phone rings or as soon as we use it the internet completely cuts off.
We have recently moved the positioning of the router to pick up a better signal and it has improved (still not the best) but now this problem has occured.
Help would be appreciated...

If you have moved it to an extension socket, then that socket may be wired up incorrectly. If you have plugged a phone into the original location of the BT Home hub, have you remembered to insert a microfilter before the phone?

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!

New iMac won't sleep with internet sharing on

Less than 3 month old iMac (core i5) has stoppped being able to sleep when Internet Sharing is enabled. It took me a good while to narrow it down to that but I've confirmed that when Internet sharing is off, it will sleep as it's supposed to. When sharing is on though, not only will it not automatically sleep per the energy saver setting, it wo'nt even sleep when forced with the Apple command. The display will turn off, but the machine does not sleep. I can tell by the facts that my wifi access on my iPhone continues to run off the iMac, and the Caps lock on the keyboard remains lit. (Too bad the blinking LED is no more on the new iMacs).
Sleep was working fine when I first got the new machine; it seems to have stopped shortly after I upgraded to Lion. (I think it may have been working for a few days after installing Lion, but I'm not positive...I'm thinking now I just thought it was asleep because the display would turn off.)
I've looked at all the related sleep posts I could find but nothing seems to address this particular issue. I know I could just turn off sharing whenver I want it to sleep, but tha't's like having to disconnect my car battery when I want to shut the car off.
Any help is appreciated.
Thanks,
Jamie

Well, I'm certainly no expert at this and I'd never enable internet sharing (being too concerned about the health of my Mac and/or not knowing what untoward sites/networks/people may be seeking access), but it seems to me that having it turned on means that your computer is sharing a connection, so anytime anyone on the network seeks access, it will either wake up the Mac or cause it to stay awake. Here is an excerpt from the Help Menu (in Finder) (which has nothing to do with your question, but I found it interesting nonetheless):
If your Internet connection and your local network use the same port (Ethernet, for example), investigate possible side effects before you turn on Internet sharing. In some cases (if you use a cable modem, for example) you might unintentionally affect the network settings of other ISP customers, and your ISP might terminate your service to prevent you from disrupting its network.

Help! Stupid Internet sharing.

So I turned on Internet sharing stupidly. And I want to connect to a normal router and be able to search for wifi signals. I have searched through the boards and seen a couple people post this question but no answers. This computer is on tiger and is a MacBook. Help me. It says Internet sharing is off but on the airport icon it has an up arrow. Thanks.

Hi Alexander,
Most likely you need to trash these files, reboot, & setup Airport & Sharing again...
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
/Library/Preferences/com.apple.sharing.firewall.plist
/Users/YourUserName/Library/Preferences/ByHost/com.apple.PrefPane.Network.<12dig itHexNumber>.plist
/Users/YourUserName/Library/Preferences/com.apple.internetconnect.plist
/Users/YourUserName/Library/Preferences/ByHost/com.apple.networkConnect.<12 digit number>.plist

Firewire Internet Sharing Probs

Hi, looking for help to resolve the following issue: On my Firewire connected cpu, I can't get past the "You are not connected to the internet." dialog in Safari. Reaching the conclusion that one or more of my settings are incorrect.
1st). 24" iMac w/ 10.5.1; connected to Cable modem via Ethernet
(there is a 5-port switch prior to this cpu)
Sharing > Internet Sharing (Firewire) - ON
Network > Ethernet > Manually; IP Address: 69.92.45.xxx - Subnet: 255.255.252.0
Router: 69.92.xx.x
2nd). Dual 1 GHz Quicksilver w/ 10.4.11; connected to 1st cpu via Firewire
Sharing > Internet Sharing (Firewire) - OFF
Network > Ethernet > Manually; IP Address: 69.92.45.(same as above *plus 1*)
Subnet: 255.255.252.0 - Router: 69.92.(same as above)
I can see & browse files within Network > Servers yet, I'm not able to access the internet.
Might anyone have a suggestion for this prob? I have searched for the answers w/ no concise results.
Thank you for any help,
Sim

simoom,
I'm surprised you're getting anything, on either computer. Let's see if we can't get you straightened out.
First, computer #1 needs to get its IP address via DHCP, not manually (unless your ISP has told you otherwise; not very common). Plus, it would be a good idea to get rid of the switch. A switch is OK if it is downstream of a router, which itself acts as an internal DHCP server, but not when connected directly to a modem.
So, computer #1 should be connected directly to the modem. It will talk directly to your ISP's DHCP server and acquire an IP address. It would appear that the Firewire Sharing is set up properly, so this should be fine once an IP address is nailed down.
Second, computer #2 needs to gain an IP address the same way: via DHCP. When computer #1 has Internet Sharing turned on, it acts just a router would, issuing "private" IP addresses to the connected computer(s), then acting as a NAT router. On computer #2, configure a Firewire network port, and set it to look for an IP address via DHCP.
