Pretty much everything is working on my N800, including all my WEP connections. WPA, however, is not. The campus LAN uses a hidden SSID and requires my MAC address and provides a username and password. This works fine in WPA Enterprise using Network-Manager on my Ubuntu Gutsy laptop: Network Name: (the SSID) EAP: PEAP Key: Auto Default Phase2: None Identity: (username) Password: (password) Anon Ident: (username again) Client Cert: none CA Cert: none Priv Key: none Priv Key password: blank In OS 2007, I am using: Connection name: (I made one up) Connection type: WLAN SSID: (the SSID) Network is hidden: checked Mode: Infrastructure Security: WPA with EAP EAP Type: PEAP Select cert: none EAP method: MSCHAPv2 Usename: (username) Password: (password) Prompt for password: unchecked (ie No) In Advanced/EAP: Use manual username: checked Manual username: (username) Require client auth: checked This spins its wheels and says Authentication Failure. One of the networking engineers has gone through this with me on the N800 and says the settings make sense and it all appears to be what is needed...it just won't connect. He said he can see the request coming through on his network monitor from my MAC address, but it fails to authenticate. The problem (in my inexpert understanding) seems to be that WPA allows for two modes of authentication: (a) client authenticates server and (b) server authenticates client, but the setting "Require client authentication" is ambiguous because it's not clear from whose perspective this is phrased: the client's or the server's :-) It fails no matter which way it's checked. Is there a known problem with WPA authentication? Or am I doing something obviously wrong? ///Peter
