since upgrade to DSM 6.0 Network troubles

[curtis777]

Hey Guys,

 

Since i upgraded my HP N54L to DSM 6.0 (DSM 6.0.2-8451 Update 9)

 

I have permanent troubles with the connection.

 

My Router Interface doesn't show up my Synology

sometimes the synology Assistant cant find the Synology.

and whe i copy a Folder with 2GB Pic's to the Synology i get Network Faults

EDIT: Ping on this IP goes most of the time negative but Webinterface is reachable.

 

allready tried to reset the synology and the router as well.

 

greetings Curtis
