I have not gone to my boss's house yet. But according to him, his wifi is on and off. I know it could be many reasons. He has triple play from Time Warner, it is an all in one type of box, it has modem, router, wifi in one box. My question:
1. Can he use his own wireless router in this type of all in one box?
2. He said he wants to get ADT this summer, and he wants to set up another router just for that, does it make sense?
3. His router is located on first fllor, with extender, the signal is still poor on the third floor (his house is not a big house, a regular NY style single family house, wood construction). What could be the possible cause?
