Guys, thank you for your explanations.
I already returned all Buffalo stuff to amazon and free to start over 
I hope that Cisco-Linksys tandem will make satisfactory solution:
E-3000 for router and WUSB600N for adapter.
However, I’m a bit scared by the bug in E-3000 that prevents WDTV from
reaching network shares:
People offer a fix (see the last post) but I’m not sure if it always works. I heard that some people even migrated from E-3000 to Netgear WNDR3700 to avoid this bug. I have Win7 64 bit so this bug may raise its ugly head. Anyone had this problem?
