If you're thinking of upgrading your home network, you've got a huge range of choice of which wi-fi router to buy. Within the $300 to $500 price, one strong contender is Synology's RT2600ac -- an upgraded version of the excellent RT1900ac, it has even faster wi-fi and the same suite of excellent add-on features like an integrated media server and VPN client. If you like tinkering with your network, you could do a lot worse than the RT2600ac.
