    Hi folks,

    effectively, I got a SNR of approx. 30 dB with my Mac mini. The signal strength is very good (roughly 90%), the noise, however, increases by every device I plug into the Mac, ending up at 46%. Even if only the power cable is plugged in, the noise yields 10%. I checked the SNR at various locations, it's all the same...

    As there's no USB3 cable involved, where could be the problem? I use one USB cable for an USB2 hub, a FW 800 cable and a DVI cable (with converter). What are your average values?

    Thanks in advance :)

    I'm using WiFi Signal from the MAS, it's free.
