Would there be any difficulty with Airport Utility 6.0 or Airport firmware 7.6.1?
Millions of users have updated with no problems at all. But, any software or firmware update always creates some unforeseen issues for a small tiny fraction of users.
As you know, we only see the problems here on the forums, so if you read a few threads, its easy to come to the conclusion that the latest firmware or software breaks everyones machines.
Chances are, if you read the posts after Lion was introduced, and based your decision to update on what you saw, you would have never updated. Same for Snow Leopard, Leopard, etc, or any previous version of firmware for the AirPorts.
No one can predict what your results may be in advance.
If there would be, how to force my airport not to look for firmware updates?
Open AirPort Utility 5.5.3.
If you are running Lion, you will need to download and install AirPort Utility 5.6 for Mac OS X Lion
Select the AirPort and click Manual Setup
Click the Base Station tab below the row of icons
Click the Options button
Then remove the check mark next to Check for Firmware Updates
Click Done, then click Update at the lower right of the window to save your new settings and allow the AirPort to restart.
Out of the blue yesterday my airport quit working, and I had to unplug it, and plug it back in to get it to work again.
Post back when you have more info on this.
5.6 works with all AirPorts. If you have any older "g" AirPorts, 5.6 is the only application that can be used to configure those devices. You cannot configure older AirPorts with 6.0.
AirPort Utility 5.6 is the full feature version for Lion. It was introduced on the same day as AirPort Utility 6.0....but apparently a number of users missed that information.
You can run both 5.6 and 6.0 on your Lion machines and use the one that you want.
Cool. Interestingly enough my Magicjack MacMini won't release the Magicjack until it reboots to make calls. Once I launch any application other than Magicjack, I must quit, reboot, and then Magicjack works again. At least now all the machines have the firmware updater checkbox unchecked. So barring a power outage, or a break in my Airport base station or an issue with the internet provider, I should be good.
I am having the same problems with my magicjack on my mid 2011 mini. Currently I'm on 10.8.2, using Airport Utility 6.1 with AEBS from 2009. The mj must be restarted after a few hours of inactivity. It wasn't always like this but I don't know exactly when it started acting up like this. My wife is really crazy that the phone doesn't work all the time and ready to kill me, and I really do not want to go back to paying monthly for phone service. I read through the posts but I'm still unsure what to try. What does using the mini as dedicated for the mj mean, and is this a must? Thank you
