SamyGO

B6000 series kernel has no network support. You needed to boot with new kernel to enable networking support, than you can load WiFi drivers.
Aquadran will add required informations to wiki but afaik it's not ready now.
You can find some information about enabling internet on B6xxx series on forum pages. But I guess it's not complete.

You can't be %100 sure of safeness..
For enabling telnet you needed to compile new kernel from SamyGO OE svn.
Than you needed to boot external firmware from USB device, this loads new kernel instead of original one that ready for Network devices.
Than you can load WiFi drivers, samba cifs modules to mount your samba share to your TV as a USB dongle...
But even I don't tried to boot external firmware. There is article to explains how to build new kernel and how to boot via bootloader...
This thing requires some linux knowledge, If you are windows guy, don't even try this
