Thanks for your response. I should of been a little more clear on my wanting a newer dual band router. I was thinking that the improved range would be more beneficial since my current router is now four years old. So in theory does a bridge take an existing signal regardless of it strength and make it stronger it the place where it is connected? Sorry if this is a total noob question.
Yeah, newer router usually will have better range w/ or w/o 5ghz using MIMO
. You could always use third-party firmware on your old router or new) and bump up the transmit power as well. Lastly, that is essential what a repeater will do, but I haven't dabbled enough into repeaters to give you more. (i.e I've read that repeaters will reduce your speed)
