I - as a DAU - bought a DS220+ with 2 drives. I was able to connect it to the UPC router (Ethernet) and set it up via PC. After the installation, however, the WLAN jammed like crazy and blocked various accesses via iPhone, iPad and also PC. I had to uninstall the whole thing so that the Wi-Fi would work again :-( Does anyone have experience with attaching this NAS to the UPC router?
