The Asus RT-AC1900P offers a solid value proposition. My speed comparisons between this unit and the Synology RT-2600ac suggest that the Asus router offers better performance, at least in my crowded, wireless-heavy apartment. When it comes to light usage—working, streaming video online, and gaming—the difference between the two is practically non-existent. However, the Asus RT-AC1900P won out in our real-world file transfer tests, and it seems to handle long ranges and walls between devices a little better.
Asus' firmware and setup processes are easy to navigate, and the monitoring panels are comprehensive and collect plenty of useful info. We just wish it was possible to export the logging data the AC1900P collects. As matters stand, you're required to look at traffic reports through a web browser. The limited 16-character length for the router's main administrator password is a little befuddling, as well, but it's hardly a deal-breaker.
If you keep your router on a desk or shelf, the RT-AC1900P is likely going to be a space-saver and offer a nice boost over an ISP-provided unit. If you'd like to mount the router to a wall, though, you might want to look elsewhere. The RT-AC1900P's vertical configuration and antennas mean the router sits pretty tall, so it could have trouble fitting into a network cabinet or a particularly high shelf.
Despite the Asus' many virtues, the Synology RT-2600ac still has its merits, as well. Its firmware is more comprehensive, better organized, and has a broader set of functionality, including the ability to export traffic reports. Plus, it can be wall-mounted. Those characteristics might make it the better choice for an office environment, even if its asking price is higher.
For home users, however, the Asus RT-AC1900P easily justifies its $180 asking price. It offers steady, solid throughput across the board and throughout our testing environment, something that a basic ISP-supplied router might not be able to do. In addition, its feature set should satisfy most users both during daily use, and when there's a need to troubleshoot network usage or set up file sharing, owners should have little trouble taking advantage of those advanced features. We have no qualms about slapping a TR Recommended label on it.
