Manufacturer description
The ASUS RT-AC68U is a dual-band 802.11ac router built for households that have outgrown a carrier-supplied gateway. Its 3x3 antenna design combines 2.4GHz and 5GHz for up to 1900 Mbps of aggregate throughput, while Broadcom TurboQAM pushes the 2.4GHz band harder than standard 802.11n gear, which matters when older laptops, printers, and smart-home devices still live on that band. A 1GHz dual-core CPU with 256MB of RAM and 128MB of flash keeps Wi-Fi traffic and USB file sharing on separate lanes, so a network-attached drive doesn't stall your streaming. Setup runs through the ASUSWRT web…
SpecPicks Verdict
SpecPicks scored ASUS AC1900 Wireless Dual Band (5GHz + 2.4GHz) Gigabit Wi-Fi Router… using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. ASUS's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
How fast is the ASUS RT-AC68U really?
It is rated up to 1900 Mbps, but that is 2.4GHz and 5GHz combined. No single device reaches 1900 Mbps; a 3x3 802.11ac client connects on the 5GHz band while 2.4GHz serves other devices.
Does the RT-AC68U support Wi-Fi 6?
No. It supports 802.11a/b/g/n/ac. Wi-Fi 6 devices connect fine at 802.11ac speeds, but you will not get Wi-Fi 6 features like OFDMA.
Is AiProtection a paid subscription?
ASUS lists the Trend Micro-powered protection as lifetime security on this model, covering malicious-site blocking, two-way IPS, and infected-device blocking. Confirm current terms on the product listing.
Can I use it as part of a mesh network?
ASUS lists the RT-AC68U as a whole-home mesh-capable router, so it can pair with compatible ASUS units. Check the listing for the current compatibility list before buying a second node.
How many wired devices can I connect?
Five Gigabit LAN ports, so five wired devices directly. It also runs three guest networks on 2.4GHz and three on 5GHz for wireless separation.
