EDIT: I tried it again, and now it works. Perhaps the last time I didn't fully screw in one or more of the connection terminals. I also performed this (this time) while the surge protector was turned on. I have a Cyber Power surge protector which has "in" and "out" connections for running coaxial cable through it. In another thread I mentioned that the person who installed my cable service said not to run the cable connection through it. This has been questioned by several GT members and so I purchased two short pieces of coax cable and attempted to set it up. Well, it doesn't work. Ok, the "in" is from the outlet to the surge protector. "Out" is from the surge protector to the modem. Any ideas? Is it possible that the coax portion of the surge protector is blown?
