Internet sharing over WiFi is broken in Mountain Lion

Anyone else experiencing this?

Just installed ML on my iMac. I have been sharing ethernet Internet to WiFi for many years through this machine. When ML was installed, it was gone, broken. I have tried everything from changing main Network Profile, changing name of the Internet Sharing Network, changing the channel, secure and unsecure, and of course restarting all devices multiple times.

I have the icon with the arrow telling me that the network is enabled, and I *have* managed to connect sporadically, but only for a short period of time and never for more than 2 units at a time. This is completely random. 99% of the time, I get the error messages (loosely translated I am afraid…)

```
"Could not connect to network …"
```
```
"Connection timed out"
```

Please tell if you have a fix and
Please Tell Apple throught their feedback system if you don't.

iMac, OS X Mountain Lion

I guess I'll be heading over to the feedback system then. After an hour of swearing and head scratching I can't seem to figure it out. Every time I want to use WiFi sharing I end up restarting everything several times until it magically works. No rhyme or reason that I've been able to find so far...

I've been having the same issue in both Lion and now after upgrading to Mountain Lion. Internet sharing will work flawlessly for awhile, until suddenly it will stop and then I get the two error messages you mentioned. The one solution that has worked for me, and was posted elsewhere, is simply renaming the WiFi network being shared by the computer with the ethernet connection. Hope that helps, although I'm sure everyone would prefer to know what is actually causing the issue...

Thanks for pitching in. This might help some users, but this was one of the first things I tried. I have used everything from only numbers, only lower case letters, long, short etc. I have done the same thing for the password, but alas…

It's unfortunate that what Jay Carr said above seems to be the case, that when it's fixed it is for no discernable reason and it really is just a matter of hoping it corrects itself. For the time being I'm going to take your advice and just report it to Apple.

10.8.1 fixed it for me. That could be because of the update itself, or possibly because it overwrote a problem permission or preference file... Sorry, I know that's not much help.

what i found it that the connecting devices seem to get a wrong DNS

putting manually the right DNS fixes the issue but i will have to adjust depending where i am - thats very not Apple
