I would look at what devices you have and what Wi-Fi they have. New stuff like phone and laptop may have 802.11ac or 802.11n. These allow higher bandwidth (you can move data faster) but not entirely necessary. Do you need Gb Ethernet?
If it is just you and network demands won't be too high (streaming TV to 1 device) you will be fine with anything. The more you pay, the more devices will work at once and the transfer of files will be faster. So it is pretty much up to your budget.
I use a Netgear N600 - services 2x desktops, 2x phones, NAS, 2 laptops, and smart TV.
A brand name is definitely recommended. I have previously brought TP-Link and Netgear.
Oh! and chances are, you'll be living next to someone with wi-fi too. Get a phone app that analyses close proximity connections/channels. If there are a lot of 2.4Ghz connections you might want to get a 5Ghz capable router. (if your devices are compatible)
