The box promises 1900. Your laptop in the next room sees a third of that on a good day — and both numbers are, in their own way, true. This page translates between the two and shows the part you actually control: where the router sits.
AC1900 is a sum: 600 Mbps on 2.4 GHz plus 1300 Mbps on 5 GHz, each a theoretical maximum link rate measured in a laboratory, at arm's length, with ideal client hardware. A single device connects to one band at a time, so no laptop ever sees 1900 of anything. What follows uses labelled ranges — real rooms, real walls — so you can judge your own setup against honest expectations instead of the carton.
The number a laptop shows as 'link speed' is the rate of the radio handshake, before WiFi's overheads, retransmissions and sharing with every other device on the band take their cut. Real throughput is commonly half the link rate or less, and your internet can never exceed the plan you pay for — a 100 Mbps plan through an AC1900 router is a 100 Mbps internet, with the router's headroom serving local traffic and stability instead. Judged this way the class is not a lie; it is a ceiling nobody's house reaches.
WiFi spreads in a rough sphere, so the router belongs near the centre of the area it serves, at shelf height or higher — not on the floor, not in a corner cupboard, not behind the TV panel. Moving a router from a floor corner to a central shelf routinely outperforms every settings change in this series combined. If the internet cable enters at an unavoidable corner, a longer ethernet run to a better spot is the cheapest upgrade in networking.
A long flat, a two-floor house, or an office with a concrete core will defeat any single router's placement. The honest escalations, in order: move the router properly first (free), wire an access point in the dead zone back to the router by cable (best quality), or accept a mesh system (convenient, costlier, slightly slower hops). A cheap repeater is the last resort — it typically halves the speed of everything that passes through it, a fact its box prints nowhere.
Walk the home or office with a phone WiFi analyser: note the signal (dBm) in each work chair. Around -50 dBm is excellent, -60 is good, -70 is workable, beyond -75 you are negotiating. Test speeds only in the chairs that matter, at the hours that matter, and write the numbers down — when you change placement or channels later, you will know whether it helped, instead of feeling that it might have.

The fixes are in order: placement, then channels, then a wired access point for that room if it is a permanent desk.
Slightly, for multi-floor homes: one antenna tilted can throw more signal up or down a floor. For a single floor, all vertical is the sane default. Antenna twiddling is fine-tuning — it never rescues a router shut in a corner cupboard.
Range is limited by law (transmit power caps) as much as by price, so a costlier box mostly buys speed and features, not dramatically more reach through concrete. For dead zones, a second wired access point beats a bigger single router at almost any budget.
