Internet Sharing not working after Lion install

Hi,

I've just upgraded to Lion and I can't get internet sharing, which was working brilliantly in Snow Leopard, to work at all.

I have reset it numerous times, changed the passwords, created new accounts but I still can't get it to work.

I use it as my home and office network and it is very important.

If anyone has had any similar problems I would be much obliged if you could share some light on this. I have read other people having issues, some managed to resolve them. But I have had no joy.

Any brave soul out there have any brilliant ideas?

hi, I looked at the post you mentioned before as well, but no luck as you say. Lion already says WIFI.

I did shorten the name of the computer as identified in the post, but it doesnt work.

I was in a hotel using snow leopard with internet sharing enabled with no problem. I upgraded and immediately could not use any anymore. It has got to be a bug they need to resolve.

I do have the same problem indeed, and noticed some interesting details.

In my home I used to share a PPPoE/Ethernet connection through my iMac. It puts my Macbook, iPhone and my gf's PC online.

After upgrading to Lion however, it puts none of them online.

If I change the "Share your connection from" option to one of my VPNs, I can get online with my Macbook, but not my iPhone or my gf's PC.

Apart from that, it doesn't work no matter how many times I change password, channel, or other options.

Hope Apple comes up with a solution before next working week starts!

Hi, I was wondering if anyone had any updates on this. There is this link on

http://forums.macrumors.com/showthread.php?t=1192376

but their answer seems to be somehting to do with the airport command still being active instead of the new WIFI in Lion. However I don't have this airport option. Since I installed Lion it has always said WIFI. Whether there is something deeper in the system that is still saying Airport is another question.

I might try deleting my old Airport preferences as they may be causing the trouble and I will get back and post if this works.

My internet sharing is also still broken even after changing the configuration from Airport to Wifi.

Irony: One day I purchase and register Applecare on my month old computer, still under the standard warranty. The next I call Applecare support to ask them about these Internet Sharing problems. Applecare support says, "we don't support Internet Sharing, will there be anything else or can I hang up on you now?". Ugh... making me regret spending more for this "premium" support.

I should say if you go to Apple and complain about Internet Sharing. Its one thingto say "We don't support Internet Sharing" but this is broken.

So its a broken part of the OS. It think they should support it....

Hey everyone, I'm new to this board, but found a way to make Internet Sharing work on OS X Lion. I didn't have the "Airport" option either, but still made it work. Here'show:

I hope this works for you as well.

Hmm I don't know how that solution could help me because I am trying to do the opposite sharing (I want to share from my wifi connection to my ethernet, essentially letting me use my Macbook as a wireless ethernet bridge). Same as you, though, worked perfectly under Snow Leopard, and I am 100% positive that it was the upgrade to Lion that broke it.

Changing the password security from 40bits (5 caracters) to 128bits (13 caracters worked for me). But I suspect that removeing all parameters for internet sharing and starting over probably also does the trick

CAVEAT!! OK Yes my internet sharing is now working and I have the up pointing arrow, which I didnt have.

BUT the two computers I had linked to this wireless network cannot connect properly to it. They try too, they can see it but the connection is weak and doesnt really work.

I change it over to the machine with Snow Leopard and everything works.

There is srtill something fishy with Internet Sharing in Lion imo...

I followed your instructions to get internet sharing working with my Apple TV 2 again after the upgrade to Lion, but it only worked for me if I left it as "Share your connection from: Bluetooth DUN" in Step 3, as is shown in your screen shot, NOT Ethernet. Did you mean to type Bluetooth DUN, I wonder?
