What happens between 09:42:40 and 09:43:16? Are there any log messages?
Apparently the client disconnects for some reason.

Things to keep in mind is that Windows Mobile requires MS-CHAP(v2)
and there may be (fragmentation) problems with large certificates.

In the RADIUS server? But after the client's authentication the RADIUS
server is not contacted again, is it? If it is a RADIUS problem,
what if you test with a static IP and a fixed password for that
