Make sure that you take a look at the security settings such as the wireless key and inspect the logs to see if there are any clues about potential issues. For example, if there are dozens of WiFi hotspots in the area where you live, you might be subject to wireless interference issues if someone else has configured their router to use the same wireless channel — try changing it from the default channel to something different.
You can also change the security settings for example to use WPA or WPA2 or remove them completely, to see if that makes a difference. If you can successfully connect another computer, iPhone or tablet for example, then it points to an issue with your Mac rather than the network kit or Internet connection.
Also, you should of course try connecting your Mac to another wireless network to see whether the problem persists. Follow the procedure below:. Locate the Command, Option, P and R keys. Press and hold down the Command , Option , P and R keys before the grey screen appears.

Another approach is to reset the main SMC chip System Management Controller , which may resolve issues related to fans, lights, video and power.
You can try deleting some of the Internet preference. Sometimes, corrupted preference files can be responsible for things not working correctly. Follow these steps:. Copy the files somewhere e. Any similar files named com. Most problems with your Mac should be fixable by the technicians there, but there are of course lots of resources on the Internet that you can also use.

Somehow that worked. I was about to throw this mac out the window. This is an excellent article, covers everything you need to know in a simple, concise manner. Get yourself a wifi analyser app on your phone, look to see which channel is the least crowded, and set your wifi router to that channel. This is the only solution that worked for me. Wow… Your advice and tips actually worked. Wish you could help me set up my idiot stick speakers now. If only! Keep up the good work! I got somewhat worries there. My knowledge of computer is limited.
