Cannot Connect to WPA2 Network

Hello. I am having a problem with my iPhone 3G and 3GS. My problem is that I cannot connect to my WPA2 network with either phone. Both phones are version 3.1.2. If I remove my security key or reduce it to WEP, the phones see the network and connect immediately, once I've put in my password for the WEP. However, once I reestablish my WPA2 connection, both iPhones see the network but after I enter the network password, neither phone will connect. I get the "Unable to connect to *** network" error. I am positive I am entering the password correctly.

We have tried replacing the 3G phone (did not solve the problem), and this network issue was actually one of the reasons I upgraded to the 3GS. Needless to say I was very disappointed to find that the problem exists on my 3GS as well.

I have called Apple but they are at a loss as to how to help me. One representative suggested I post my problem here and maybe the "very knowledgeable Apple community members" could help me (those were his exact words)...

So, can anyone please help me?? Thank you!! 🙂

3G & 3GS, Windows XP Pro, SP3 Installed

BlueWinged Angel: I am having the exact same problem as you. But one thing I have noticed, is that my iphone's name is not showing up in the DHCP list/overview on my router. Normally, and like many of my friends' iPhone, it should show up as "[My name]'s-Iphone". But in my case, depening on which router I'm conected to, the name-field is just blank or it says "Unknown device". I think the WPA issue could be because of this.
So my question is: Are you experiencing the same?

BlueWinged Angel, not too sure if you are still having problem connecting your iphone 3Gs to your LinkSys Router using WPA2 Encryption. I faced the same problem and the following router setup resolved this problem:-

(1) Wireless Security > Security Mode -- Set to <WPA2-Personal>

(2) Encrption -- Set to <TKIP or AES>

(3) Save Settings

If you don't see the option selection, please flash to the latest firmware at Linksys website before repeating the above procedures.

Other security settings on the router can lock you out such as MAC address filtering. Is MAC address filtering set to "on"?

The Wireless MAC Filter is disabled. Is this what you mean??

I'm assuming here that your router is set to broadcast "G", not "N", as the iphone only works at "G" speed.

It is set to "mixed" because I have b, g, and n devices on my network.

Should I change it to g only just to see if that works or should the "mixed" setting have covered that??
