Probably the only hitch on the RT2600AC router is the number of network ports. While we do get one standard WAN port, the router only features 4 other LAN ports. Do note that you can use one LAN port as a secondary WAN port if required. However, this only leaves you with 3 LAN ports for wired clients. You can increase the number of ports using an adapter or dongle, but just as a future note, Synology should really consider including more LAN ports just for convenience.
The shortage of ports, however, has no effect on the absolutely mind-blowing performance. On the 5GHz band, the Synology RT2600AC Router topped the charts with sustained speeds of around 715Mbps at close range (15 feet). Increasing the distance does bring the average down to around 450 Mbps, but that too is pretty impressive.
On the 2.5GHz band, the router hits speeds of 250Mbps at close range, while increasing the distance dropped the average to 120Mbps. Not the best numbers on the chart, but do keep in mind, that the industry is now adopting the 5GHz band as the standard, which has brought down the attention on the 2.5GHz band by a considerable amount. That said, these numbers should give you a handy connection anyways.
