ASUS RT-ACRH18 AC1750 dual-band Wi-Fi router: features, specs and who it suits

The ASUS RT-ACRH18 is a dual-band AC1750 Wi-Fi router for home networks. It uses the 802.11ac standard, also called Wi-Fi 5, and is meant for households where phones, laptops, TVs and tablets all share one connection. This page explains what its numbers mean and what it can and can't do.

What "AC1750" means

AC1750 is a combined figure, not a speed any one device will see. ASUS lists up to 450 Mbps on the 2.4GHz band and 1300 Mbps on the 5GHz band, which together add up to roughly 1750. Real speeds depend on distance, walls, interference and what your devices support. A phone or laptop with a single antenna typically reaches a fraction of the headline numbers.

The two bands work concurrently. The 2.4GHz band reaches farther and passes through walls better. The 5GHz band is faster but covers less distance, and it suits streaming and video calls when you are in the same room or nearby.

MU-MIMO and beamforming

MU-MIMO (multi-user, multiple input, multiple output) lets a router communicate with several compatible devices at once, rather than serving them one after another. ASUS says it connects MU-MIMO-compatible clients at each device's maximum speed simultaneously. Only devices that support the feature benefit.

AiRadar beamforming focuses the signal toward connected devices, instead of broadcasting evenly in every direction. ASUS says this improves stability and coverage. It states a maximum range of 3,000 square feet; walls, floors and building materials usually shorten the practical reach, so treat it as an upper estimate.

Setup and control

The ASUS Router app handles setup and day-to-day control from a phone. Parental controls let you manage how connected devices use the network; the listing describes them as a way to protect children from internet addiction. The router also has a USB 3.0 port, which on most routers can be used to share a storage drive or a printer across the network, depending on the firmware features. Check the manual for what this model supports.

Power and size

The router works on 110V to 240V input at 50 to 60Hz, with a 12V DC output at up to 1.5A for the power adapter. It measures about 8.7 x 6.3 x 3.4 inches (roughly 22 x 16 x 8.6 cm) and weighs about 1 lb (0.45 kg), so it fits on a shelf or desk.

Who it suits

It suits small to medium homes and apartments with a standard internet connection, and people who want a straightforward Wi-Fi 5 router with app-based setup. It isn't a Wi-Fi 6 or Wi-Fi 7 device, so it won't use the features of newer standards. Check the plan speed from your provider, since a router can only pass on what the connection delivers.

What to check before you buy

• Home size and layout: large or multi-storey homes with thick walls may need extra access points or a mesh system.
• Internet plan: confirm your plan's speeds fit within what a Wi-Fi 5 router handles.
• Modem: this is a router, so it needs a separate modem unless your provider supplies one.
• Your devices: MU-MIMO and 5GHz only help if devices support them.
• Wired devices: check how many Ethernet ports you need; the listing doesn't specify them.
• Updates: follow the manual and brand guidance on firmware updates and passwords.

The short version

• Dual-band AC1750 (Wi-Fi 5) router: up to 450 Mbps on 2.4GHz, 1300 Mbps on 5GHz.
• MU-MIMO and AiRadar beamforming for several devices and steadier signal.
• Up to 3,000 sq ft of stated range, with USB 3.0 and parental controls.
• Set up and managed with the ASUS Router app.
• Compact, about 1 lb, with a 110-240V power adapter.
