Ok, I did some research homework and I think I understand your first answer better now.
So you were saying I need to install an opkg-package in order to make the RUT955 learn how to speak SMB1
I have also learned, that the opkg package needs to be compatible in order to work - which brings me to my next question:
Can you help me find a package?
Or can you tell me where I need to look?
Maybe you have some information about what I need to loo - for example: opkg package compatible with openWRT Version: 12345678
Any help here would be greatly appreciated!
