Fix for Mac OS X 10.7 Lion Wi-Fi Dropouts and Inconsistency

For the most part, Mac OS X 10.7 is a quality update, considering that it’s fairly affordable. However, many Mac OS X users have reported problems such as dropouts and inconsistency with Wi-Fi (previously Airport), in 10.7.  When I upgraded to 10.7, my MacBook was getting very inconsistent wireless. I figured that OS X updates (Apple Logo > Software Update…) would fix the problem, but even after installing the most recent updates, Wi-Fi still only worked some of the time.

I also searched the web for possible fixes, none of which worked on my MacBook. For the most part, the fixes included:

- Restart your Mac.

- Turn Wi-Fi off, wait a couple of minutes, then turn Wi-Fi back on.

- Unplug the wireless router and cable modem, wait a couple of minutes, and reconnect.

Turning Wi-Fi off and then on worked momentarily, but the Wi-Fi issue still dropped frequently, which became quite annoying. Basically, what was happening, was that Wi-Fi was randomly disconnecting, although it appeared and still showed full signal strength.  I could turn off Wi-Fi, then turn it back on, but this only fixed the wireless problem temporarily. The next time I would use Safari, the wireless would randomly drop again.

Next, I tried re-installing Mac OS X all together (clean install), but what a waste of time that was. I did end up finding a fix for the Wi-Fi, which I will describe in the next paragraph.

To fix Wi-Fi in OS X 10.7

Turn Wi-Fi off for your Mac.

Launch System Preferences, click on the Apple Logo and select System Preferences… from the context menu.

Mac System Preferences

Select the Network listing, which is listed under the Internet & Wireless section.

OS X System Preferences  Network

Select Wi-Fi from the left-side network connections list and click the - symbol to remove the connection.

+ Wi Fi OS X

Re-add the Wi-Fi connection by clicking the + symbol. Assure that Interace: is set to Wi-Fi. You should also name the connection with the same value Wi-Fi.

Once you have finished adding the connection, turn on Wi-Fi.

That’s all there is to it. For some odd reason, that fixes the Wi-Fi problems in 10.7. I have not had dropped Wi-Fi since I applied the above steps.

Thank you for stopping by the site for today’s post. If you have any questions regarding Wi-Fi, or your Wi-Fi is still not working correctly, leave a comment and I will try and help.

    Is that meant to be "assure interface is set to Ethernet" as shown in the screenshot?
