Hi jsk2,
Thanks for the suggestion. No, I haven't tried to move the router to the 2nd floor. Is that supposed to improve the signal house-wide? The 2nd floor coax is on the opposite end of the house of the 1st floor coax.
Also, might be a really stupid question, but can the coax cables be used interchangably? (ie: the coax for my TV can be used for the router, and the coax for my router can be used for a TV)?
Thanks!
