(I tried TKIP later, when this didn't work, with the same results as described below.) So I set it to WPA-PSK / AES and entered my security key.It's mixed letters and numbers, 32 characters long. Still "waiting for reply" in the main screen, and "cannot find certificate" on the pop-up.It can find the network fine, but when I try to connect, I don't get the password prompt -- it moves straight to "validating identity," scans, and then says "Windows was not able to find a certificate to log you on to the wireless network Foo." The maddening thing is that the card was working fine a week ago, in the same box, using the same OS.I pulled everything out, swapped out the motherboard, and reinstalled Windows on a freshly wiped hard drive, and now I can't get it up and running again. I've taken several runs at it, including attempting to manually change the settings for the network to include WPA-PSK and AES and the password, and I'm a bit worried that I've totally boned everything.With PEAP many organizations can avoid the issues associated with installing digital certificates on every client device as required by EAP-TLS; instead, they can select the methods of client authentication, such as logon passwords or OTPs that best suit their corporate needs.Also PEAP is an enhancement of EAP-TLS authentication, PEAP encapsulates a second-phase authentication transaction within the TLS framework. WZC is windows built in Client service for Wireless Networking.
For detailed information about how to deploy a wireless LAN using IEEE 802.1X authentication, see Deployment of Protected 802.11 Networks Using Microsoft Windows. PEAP provides more security in authentication for 802.11 wireless local area networks that support 802.1X port access control.PEAP authentication is managed between the PEAP supplicant and the authentication server (Radius).This article assumes background knowledge in IEEE 802.11 wireless LAN and associated security technologies and the components of a Windows-based authentication infrastructure.For background information, see Wireless LAN Technologies and Microsoft Windows.
