Hi Swedst,
I had this problem also until I decided to mock around with the original settings on RSSM. It seems when it comes to connections the default option is set to use 25% of the available bandwidth on your network. Change this to full and recheck for updates. This time the check will take a little longer, but once it is done you will see 5 packages on your list. Make sure you are at the console of the system to install these as I had problems install this remotely.
Hope this helps,
Jesus
