So we have had AT&T internet here at our house for about the last 8 years and still have the router they installed in place. My friend just gave me a Nighthawk AC2300 router and I was hoping to install it in place of the AT&T router to make things faster. Over all the AT&T router does ok but is weak as far as connection stregnth in the far corners of the house and downstairs. We added one of the small TP link extenders downstairs and that seems to help some but now when Im upstairs my laptop seems to want to connect to that access point downstairs and when Im downstairs it wants to connect to the main AT&T router upstairs, so basically just not good. The AT&T router is the standard one that says AT&T all over it and is made by a company Pace, I do not see a model number on it. As far as usage we have a few iPads, laptops, phones, stream TV, nothing major. There are no instructions included with the Nighthawk router. Is it a simple install to replace the AT&T router with the Nighthawk? Thanks in advance
