I have an IMAC 12,1, Intel Core i5, 2.5 GhZ, Mac OS X (10.6.8 version).
The wifi is stoping continously, each 30-40 minuts or less, I have to select again my Vodafone network (and several times the computer asks to write again the key of Vodafone). This problem does not happen with my macBook Air or my iphone.
Can you help me?
Are you sure you are running OS X Snow Leopard 10.6.8? Check under the Apple menu>About this Mac. If you are running a later version of OS X, these general WIFi troubleshooting suggestions may be of some help:

Might be corrupted network preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
Yes, it is correct, precisely I have copied from my computer.
Thank you Carolyn. I have done it and reconnected the ariport, but the problem is not solved.
Are there other possibilities?
Someone can help me? The problem is still there. Thank you
Do you have more ideas? The problem is not solved !
There is a WiFi Diagnostics application on the Mac. Please take a look at http://osxdaily.com/2012/07/31/wi-fi-scanner-mac-os-x-mountain-lion/
but you are running Snow Leopad. (10.6) 😟
Can you run About This Mac -> More Info and take a screen shot using Grab. Remove your serial number and post the screen shot. SL 10.6 is old. It may be what originally shipped with the iMac.
Do any of your other devices show wifi issues? Are they connecting to the same SSID as your iMac. You should also look at Applications -> Utilities -> Console and check logs for Airport activity.
HERE YOU HAVE THE INFORMATION. I have a MacBook Air and and Iphone and they are going OK with the same network

Can you check messages related to 'Airport' in Applications -> Utilities -> Console on the iMac. You can also compare these to the ones from MB Air and check if during the time window when iMac has an issue, does the MBAir see similar messages?
The majority of these are not for Leopoard. i have reviwed them and made some proofs. But the poblem is not solved
When the wifi connection stops the CONSOLA does not change. It stoped at 14.29 and this is not registered. See the last registers:

1. Please run /System/Library/CoreServices/Applications/Wireless Diagnostics.app
2. On the main window click on Command+2 which should bring up a new utilities window.
This is what it looks like.
Click on Performance and you should see...
This should show what is happening to the iMac connectivity and when it drops. Both graphs together should help.
You want to do the same thing on the MBAir and compare the two, side-by-side.
For older versions, please take a look at https://supportforums.cisco.com/document/75221/wireless-sniffing-using-mac-os-x- 106-and-above
I think that this no exists for 10.6.8 (what I have).
I see that it is difficult to find the cause of the error.
Wifi stops on IMAC
