"A connection timeout occured"

[tekno]

I get this A LOT on my 2011 MacBook Air when trying to connect to either my Airport or O2 Wireless box, so I'm guessing the problem is definitely with my Mac.

Could anyone explain what this is, why it happens, and how I can stop it?!

So everything is peachy u just want the annoying message to go away?

I only ever had this problem when I tried setting my billion wifi router setting to wifi power save on.

My MBA couldn't connect showing that timeout message so I turned power save back off.

Also try picking a different wifi channel: 1, 6, 11

When does the issue occur? During normal use? When waking up after opening the clamshell?
