Fix OS X Mountain Lion Wireless Connection Problems
We’ve made a crux of it and gotten the best solution that most users say has worked for them. You can try them – they’re not geeky or lengthy processes – and tell us if it worked for you.
Method #1
Users have reported that this method has worked like a charm. It’s easy and it has a very high success rate. Here we go:
There’s something called MTU (Maximum Transmission Unit) which seems to be a source of the problem of constant loss of network connection.
• Open System Preferences (from Apple Menu)
• Select “Network”
• Now click “Advanced” button in the lower corner
• In the tab that opens up, select “Hardware” (right-most option)
• In the “Configure” drop-down, select “Manually”
• And in the MTU drop-down right below, select “Custom”
• In the text-box right below, enter 1453
The 1453 seems to be a standard CISCO number – I don’t think we need to delve deep into it. You can read more about MTU here.
Method #2
This one is a bit lengthier than the previous one but it’s another method that can help.
• Open System Preferences from the Apple menu
• Choose “Network”
• Click the “Location” menu, for the drop-down and
• Click “Edit Locations…”
• Now, click on the ‘+’ to add a new location.
• Give some random name to the new location and then click Done
• Head back to the Network menu and then choose the new network.
Your network should be working fine now, but let’s renew the DHCP lease.
• From the same Network panel, choose “Advanced” option. (lower-right corner)
• Now click the “TCP/IP” tab
• In the Configure IPv4 drop-down, choose Using DHCP.
• Now click “Renew DHCP Lease”
• When prompted, click on Apply.
• Click OK and come out of the options.
All this should actually fix OS X Mountain Lion wireless connection problems.
If however even these don’t fix the problems for you, you can try the last method:
Method #3
• Do a complete “fresh” re-install of the entire Mac OS X 10.8. This should fix it for sure.
