According to the back of my mp2150, there is a jack for IR IN. Apparently the MP2000 gateway calls the same jack an IR Blaster. Whatever it really is, How do I run my 2150portal behind cupboard doors? Both Shaw and Arris seem very vague on how to do this even though Arris seems to sell an IR tether. Which apparently was supposed to come with my unit from Shaw but, like many others on this forum, it did not. What gives?
