Re: Can't Connect: Connection Timeout?

Question

What could be the possible reason for getting "connection timeout" after failing to connect to the internet? After going to Network Prefs, clicking on my network, being prompted for my WPA security password and getting the message "connection failed, " this is replaced with connection timeout?
Reset my modem and AEBS (unplugged and plugged back in), and was able to connect.
Any relation to whether or not, under the Airport tab of Network Prefs, "Disconnect from wireless networks when logging out" is checked or not? I don't have it checked, and don't remember having it checked, but someone on the Airport Discussion boards said it should be checked?
What other possible reasons fro getting a connection timeout? MY ISP says there is nothing from their side that would timeout my connection.

After reading this entire thread, I conclude that I am having the same problems. Here's what I'm seeing:
* The problem only happens when using WPA; switching my WAP to WEP or no security makes all my Mac's consistently connect just fine.
* When the problem occurs, I am prompted for the WPA password; when I type in the password and click "connect", it alternates between "Connection timeout" and "Invalid password" (I'm positive that the password is correct; it's short, simple, and I'm using the "show password" checkbox to verify that it's correct).
* My Intel 10.5.2 MBP usually connects ok (airport card -- 802.11b/g).
* My PPC 10.5.2 iMac usually connects ok (airport card -- 802.11b/g, sometimes it asks for the WPA password once even though it's stored in my keychain).
* My Intel 10.5.2 24" iMac rarely connects ok (airport extreme card -- 802.11b/g/n, with the symptoms above).
* Windows laptops connect just fine.
* There seem to be several different WAPs discussed on this thread; I'm wondering if there is some kind of WPA protocol issue in 10.5.2 because I can consistently WPA connect just fine to a Linksys WRT54GL, but I see the symptoms described above with Cisco Aironet 1131AG's.
To reiterate: the problem most consistently occurs on an Intel iMac with an airport extreme card with OS X 10.5.2 when connecting to my Cisco Aironet 1131AG when WPA is enabled. It definitely does not occur when WEP or no wireless security is enabled. It rarely happens with a PPC iMac and an Intel MBP, both with OS X 10.5.2 and airport cards (regardless of network security settings and WAP used).
