Windows + 802.1x

[Yury Shvedov]

Hi, Thanks for your reply.

But I had the problem with Windows7 and already found its source (my
mistake). But now I have another problem with Windows in rsn
environment. Windows connects successfully, 4-way handshake(RSA) done,
and even there is an Internet for windows client. But in the windows's
network menu against my network there is red cross and client always
disconnects and connects.

Have someone ever faced with such problem?
Thank you.
