I am looking to set up a second router in my house to: get better WiFi coverage in the back of my house since the first router's WiFi does not do well back there, and have Ethernet access for the two computers back there. I want to connect the routers through an Ethernet cable run through the attic as detailed here. My first router, which I am not looking to replace, is a Linksys EA6350. I am wondering if I should get the same one so they are consistent, or if that would create problems, or if there is a particular router recommended for a two router setup. Thanks.
