(Edit: 2010-06: my problem was solved, see settings below)

Why can't I select the certificates I installed wireless networking? It isn't showing up in the wireless connection settings.

I am trying to connect to my organization's wireless LAN, it uses WPA2/AES with PEAP + MSCHAPv2. I don't have much Linux or networking experience, so I apologize if I am making an obvious mistake:

These are the steps I took:

1. I downloaded the .pb7 certificate files, and saved them to a random folder on my Nokia N900.

2. I followed: http://talk.maemo.org/showthread.php...L+certificates. I used 'File Manager', clicked on the certificate to install, got the 'install certificate' window. I selected all the purposes (initially i tried just 'Wi-Fi', but it didn't show up in step 4 below, so i selected all the purposes, but it still doesn't show up in step 4).

3. I verified the certificates are installed through the "certificate manager" (under Applications -> Settings -> Certificate Manager). The certificates show up with all the purposes listed, so I think they are installed properly.

4. I tried to set up the WLAN using the instructions from http://wiki.maemo.org/PEAP%2BMSCHAPv2 (and Slocan's suggestions below). I used these settings:

• Network Mode: Infrastructure
• Security Method: WPA with EAP
• EAP Type: PEAP
• Select Certificate: NONE (no other options)
• EAP method: EAP MSCHAPv2
• User Name: domain\username (note: this was the problem, username@domain didn't work)
• Password: (password)
• Advanced settings - EAP: Use manual user name = Selected
• Advanced settings - EAP: Manual User Name = domain\username
• Advanced settings - EAP: Require Client Authentication = Unselected

Note that the certificate doesn't show up in the menu for 'Select Certificate'.

5. Connect to the wireless, but all I get is a 'Authentication Failed. Try Again?'

I think the problem is step 4. Why doesn't my certificate show up under the drop-down box for "Select Certificate"?

Thanks for any suggestions people might have.

... More info: My Mac pretty much automatically figures out the settings. I was given the Windows XP settings required:

• Network Authentication: WPA
• Data encryption: TKIP
• EAP type: Protected EAP (PEAP)
• Selected "Authenticate as computer when computer information is available".
• Select "Validate server certificate", and select the certificate to use.
• Authentication Method: Secured password (EAP-MSCHAP v2)
• Infrastructure mode only
