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.
Select the Network listing, which is listed under the Internet & Wireless section.
Select Wi-Fi from the left-side network connections list and click the - symbol to remove the connection.
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.
