I'm also on UPC in Austria, and yes, I'm suspecting the same issue now. I will switch to Bridge mode now because of this.
Maybe it's an issue with the cablemodem? There aren't many different manufacturers of cablemodems. What's yours?
Actually I received a new one yesterday. I have to check again whether the issue persists. The new one is called "Connect Box" and is jointly manufactured by Compal und Arris.

Also using Connect Box. No interest in switching to bridge however as I have no device capable of connecting by itself.
Interesting. Every once in a while I have issues on my cable provider (UPC in Austria) with S3 and S3 only. Next time that happens I gotta have a closer look at it.
