I have had the SamKnows whitebox since March 2012 and it has caused no problems for me. The only issue I had is when my Mediacom cable modem failed and they sent out a tech to check it out. When he saw the Samknows box he didn't know what it was and said my connectivity problems were caused by "double routing" and that Mediacom didn't authorize use of such a device on their network. I knew it wasn't true, since my SamKnows invitation initially came directly from Mediacom corporate and the SamKnows had worked fine for 3 years, but I agreed to remove the box. Of course, that didn't fix the problem, and he put in a new cable modem and told me not to hook the SamKnows back up because they would not be able to provide future assistance if the SamKnows box was in the mix. I waited until he left, then reconnected the SamKnows box and have had no further issues.
