Hi all,

The problem was not more than one DHCP server on my LAN.
The solution was to not boot with WinAMP that tried to read from my Flexshares, before I entered a password for it.
For some reason it sometimes locked up the connection for about 10 minutes, before I was able to login to my Flexshares manually.

It has been working fine now for the last couple of weeks, so I guess that this was the cause of the problem.

Greetings,

John
