What you can do for now is just disconnect it until he returns,& then he can set it up again. One thing,I wouldn't have the CCK hooked up on the same cable as the power inserter. If you can't get the CCK to work,you really shouldn't need it with the HR34(from what I've been told,I haven't made the jump to HR34 yet. But other HR34 owners will confirm this),just hard wiring the ethernet cable to the HR34 should accomplish the same principle for whole home DVR set-up. Your other DVR's should be connected to the internet through your HR34. Then you could see if you could get a credit for your CCK not working.
