Internet sharing not working anymore

Can I ask which model of MacBook Pro you have ?
I found someone has the same problem, and we both have model "MacBook Pro3, 1".

I have a first gen iPhone and just got mine working today by following these steps.

The following procedure is confirmed to work as written.

Start Internet Sharing if it's not already running.

In Terminal, type cp /etc/bootpd.plist /tmp/bootpd.plist

Stop Internet Sharing.

Open "open -e /tmp/bootpd.plist" for editing using TextEdit or whatever.

Locate this section of the file, near the end:

<key>reply thresholdseconds</key>
<integer>4</integer>

Change the value 4 to 0.

In Terminal, type sudo cp /tmp/bootpd.plist /etc

Start Internet Sharing.

If you want to, check that your change to /etc/bootpd.plist hasn't been reverted.


Then i just restarted my phone and everything seems to working for the past few hours.

it doesn't work for me.

the file /ect/bootpd.plist does not exist at all.

It's

/etc/

not

/ect/

sorry.

cp: /etc/bootpd.plist: No such file or directory

/etc/bootpd.plist only exists (at least before you've done any tinkering) when Internet Sharing is turned on.

That said, this did bupkis for me. With internet sharing turned on (share an ethernet connection via airport on my black macbook) I can neither browse on the macbook OR anything connected to it (iPod Touch, XP laptop, Vista laptop, etc).

Prior to Snow Leopard, this worked like a gem and let me use my Macbook as an impromptu airport base station.

I'm going to guess, however, that the problem has to do with the airport settings in some manner, not internet sharing itself.

Think I figured it out.

Turn off internet sharing.

Go into system preferences -network

Click on Airport in the left hand side, then click 'advanced' on the right hand side'

Click TCP/IP and turn 'Configure IPv4 to Off

Click OK, then click 'Apply' in the network window.

After that I am now back to normal and my network is up and running again without problems.

Forgot...after you do that turn internet sharing back on...duh.

it doesnot work for me。

/etc/bootpd.plist is under /private/etc

fyi

Make sure Airport is on. If not, it may refuse to start. Try logging out, then logging in to restart Airport, then activate Internet Sharing. Worked for me but your mileage may vary.

Seems like there is two very distinct problems regarding airport and internet sharing. First one, ( which was the one I had) was I wasn't even able to create an internet sharing connection. Meaning my airport icon failed to become an arrow pointing up. Second issue is users connecting to the ad-hoc but not getting any real internet connection.

There is a solution for the first one: I will repost here:

Guys this solution worked for me. I will repost: by mesagsx

I have a solution, and it worked for me today, which should make everyone here happy.

* Under airport menu, go to "open network preferences"
* Under "advanced" in the airport tab, click on "Require Administrator password to ... create computer-to-computer networks".
* click OK
* click apply
* under airport, create a network (using some unique SSID name, like blah1)
* under airport, disconnect from blah1
* go back to your airport prefs again (see above)
* uncheck that annoying option about requiring administrator password, etc...
* click OK
* click apply
* go to internet sharing and do your thing like you usually did before.


I'm guessing this is just a bug with a SETUID permission on an executable, now that this option has been added to snow leopard ... and the setting of that option, and subsequent unsetting of it is enough to get the setuid bits all correct.
