AirPort “Connection Timeout” issue | January 4, 2008
It seems there is a glitch in the AirPort connection dialog (or underling software) in Leopard that will occasionally prevent you from connecting to a wireless access point with a “Connection Timeout” message (usually involving WEP, which is yet another reason to upgrade to WPA). While frustrating, if you find yourself in this situation there is a solution: open up Safari and click your way through the the Network Diagnostics Utility (a button to launch this appears when you launch Safari and it can’t connect to the internet). This will successfully allow you to connect to the wireless access point (provided something else isn’t wrong anyway). As usual, I’d assume that there will be permanent fix for this soon, but at least for now there is a work around.

Thank you so much for this fix! We just got a new linksys router and I was so frustrated upon trying to connect it to our network using the built in airport issue, but your workaround surprised me by working instantly without any problem :)
Thanks for your help, and I hope Apple can fix all these bugs with the leopard wireless issues that users have been reporting :)

[...] the very ugly… I can no longer find my WiFi network at work, not at all! In my last post I noted that there were issues connecting to the Fortinet FortiWiFi 50B at work. This was annoying, [...]

Didn’t work for me… Other suggestions?

Didn’t work for me either. I just got the same ritual as through AirPort. It recognises the wireless router but asks for the WEP each time and then gives the ‘Connection Timeout’ message. Or ‘Incompatible security’. Everything was fine until yesterday and two PCs are working off the same router.

Yeah, it worked after it gave some error that it was unable to connect. Amazing.
Thanks :)

Damn.. doesn’t work anymore at all. Sucks

Unfortunately, there is no difference for me, still no connection. And I have no problems with connecting to a dozen of other wireless networks (at the some time I have no problems with connecting 4 PCs to the problematic AP).

Very strange indeed, but working for me too! So thanks from me also. I’m using WPA2 by the way, so WEP is not the cause.
Glad your site shows up first in Google when searching for ‘connection timeout airport’ :)
Cheers!

I found unplugging the airport unit - waiting a few seconds and plugging it back in - helps. Airport found the connection without any problem. I experience this problem once or twice a month and have yet to find out what causes it.
Thanks for this site though.

Thank you. It didn’t work through the Safari workaround but when I changed the Router to WPA, it finally connected. Thanks again.

This fix simply does not work (not for all anyway). Can anyone kindly help me with another option?
I cannot find any fix that works other then re-installing the OS from scratch which i am loath to do and unsure it will help me…Help !!!
