Which router do I get?

[hammad1029]

Hey, so I live in a two floor house and want a router that can provide WiFi to both floors. I am using a tp-link tl-wr740n v4 and it was good enough to provide the part of the house with WiFi where my family sat most in. I now switched places and so I have a WiFi problem so can you please suggest me a good router with 2-3 antennas, maybe dual band WiFi(no prob if there isn't), a good wireless range, gigabit LAN ports(at-least one) and good reviews under 30-40$. I was about to go for the tl-wr940n v3(30$) but it doesn't have any gigabit LAN ports and as Linus says "get gigabit even if it means spending a couple more bucks". Tell me if I should go with the tl-wr940n v3(30$) or suggest some others
