Thanks a lot for this post! I updated my mac a few days ago and have been having wifi problems since.
Dude,you saved my life tonight.. Thanks, it seems that you have a very large knowledge on this subject. We can see the router on airport, but it seem that it would not aloud us to get to server. Any ideas? Handy thanks! Always-on Connect-on demand being set to Connect on demand instead of always on. Thank you! Thanks for nothing Chriswrites. Very ambiugous instrucitons. I rarely comment on articles, but I will here to warn you of a problem with your instructins.
Got to step 2 on the remove and re-add wifi. Removed wifi service, went to re-add, but your instructions are unclear, guessed that I was to add the name of my wifi service and now I have a status message that says my wifi service does not have an ip address and cannot connect to the internet.

Thank you Chris. I was trapped on an overnight layover in Narita Japan. Nearly six hours were spent googling and trying suggestions found with my iPhone. But it was your great advice to remove and re-add the WiFi service that got my laptop back on the Internet during the rest of my 19 hour layover. I literally searched the internet for over an hour to figure out the problem with my mac. This website is the best!
Thank you so much!!!!! You saved me time, money, and frustration!!!
Deleting preferred wireless networks on Mac OSX
Thank you so much!!! Thanks, just upgraded to Mountain Lion from Lion and the Wifi dropouts started immediately. I did everything listed above and now the connection is solid — Over 5 hours so far with no dropouts. Thanks for posting this information. Thank you soooooo much! Great article. Eventually I got it to work by going into the router admin address http: 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!
