I went to buy a internet wireless router. The cashier asked if i was with shaw. i said yes, he said i dont need to buy a router. He said shaw has this cable router that is connected to this black box wi-fi route. All I have to do is call shaw and say I wanted the wi-fi router turned on. Is this wi-fi router true, i have this router in my basement at connets to my cable router and it does look like it is a wi-fi router. Help?
