This post will go over Mac 10.6 reset network settings. This is needed if all network settings look fine on OS X 10.6 but the machine still can't get on the internet.

Give this a whirl:

  1. Open Network Preferences
  2. Open the Location selector at the top of the pane
  3. Click Edit Locations…
  4. Add a new location by clicking the plus sign.
  5. Name it something and click Done
  6. Select this new location (all network settings are back to OS X defaults)
  7. Return to Edit Locations…
  8. Delete Automatic by selecting it and clicking the minus sign
  9. Double-click on your new location and rename it to Automatic

Note: This procedure deletes all network settings and restores them to their OS X defaults, including those settings without a GUI representation. If you're just wanting to do basic wireless troubleshooting, head over to the Troubleshoot Mac Wireless post for more information.

I also found this little tidbit about iMacs – make sure you're using WPA2 security instead of WEP. Not only is the security better, iMacs seem to work more reliability with this type of connection.

Reinstalling Network Adapters

If you need to go beyond resetting the saved networks, you can rest the network adapters by following below. You will need administrative privileges to be able to move forward.

  1. Open System Preferences
  2. Choose Network
  3. Click the network adapter and press the minus sign
  4. Click Apply
  5. Restart your computer to save the changes
  6. Repeat steps 1 and 2
  7. If the network adapter is not back in this list, click the plus sign
  8. Choose the network interface that you previously deleted, name it, and click on Create
  9. Click Apply to return functionality back to normal

That's it for this Mac 10.6 reset network settings post. Post any additions you have from your efforts.
