my name is Robert and I have a configuration problem on my C851w router. Wireless connection without eap authentication works well but when a configure eap with a local radius server than the authentication works not well - you will see in the config in that attach.
On the Client site (WIN XP ServicePack2) I write username an password in the authentication popup windows and it looks good but after a few seconds I see a authentication failed. I can see with Wire shark a packet "EAP failure" Packet that a receive from my router. I use 802.1x with PEAP on the default WIN client.
In the radius debug you can see the router tried it more times (see in the attach)
I hope somebody can help me.
P.s. the guest-mode in the ssid is only for the configuration in this ssid
