In reply to DS.

It seems to work fine, as the NIM uses 950-1150mhz, above what Comcast uses. I have not tried it since upgrading to DOCSIS 3 earlier this week. I took the NIMs out as I was having some speed issues, which were not related to the NIMs as it turned out, but I have not put them back into service yet. Too many snow issues to deal with :)
