Hi Žygimantas,
yes, the problem was raised multiple times in the forum, but where is the solution? The path does not exist, so it should be fixed.
.../packages/mips_24kc/vuci/Packages.gz
The queue problem is, that the WOL package is searching for updates on and on and not getting them so I think these two problems belong together.

When clicking refresh a popup appears that the device network should be checked - but hey - i am connected to it, where is the problem?

As said previously, resetting the RUT settings is not an option for me.
