After installing the latest Windows 8.1 updates ( May important updates ), shutting down and powering the PC on, the unidentified network is now named ''network'', but still shows limited, anyway was asked if to connect devices printers etc on this networks so at least it s recognized by Windows..
Net works fine but under the network there still shows ''limited'', connected trough broadband, no router in my flat, there should be some similar device on the stairs of my building, it is labeled ''100 Mbps'' and has a small padlock on the door, I have no idea how to mess with that, I'll probably have to call my ISP to be sure, but I still suspect Win 8.1 for the ''limited'' error, I see it all over google when looking it up.
