  • Product DetailsBack to top
  • Ideal for streaming high definition video, the Asus RT-AC51U Wireless Cable Router offers high transfer speeds, allowing you to form a perfectly connected home.

    Speedy WiFi

    Powered by a dual-core processor, the RT-AC51U allows you to stream HD video, take part in online gaming and download files in a flash. It includes dual band technology for reliable, uncluttered wireless connection.

    The 2.4 GHz band can deliver up to 300 Mbps, whilst the 5 GHz band can deliver up to 433 Mbps. This means that you can take advantage of the 2.4 GHz band for simple internet tasks such as web browsing and file downloading, whilst the 5 GHz band is ideal for streaming in Full HD or online gaming. Broadcom TurboQAM technology helps to improve the router's performance, so you know you can rely on this device.

    Signal range

    You won't struggle to connect to your network thanks to Asus AiRadar technology. Whilst other wireless routers may have weaker signal, the RT-AC68U uses beamforming technology, high power amplification, and RF fine-tuning. Not only does this help to boost coverage throughout your home, but it also helps to keep your connection stable and speedy.

    Fantastic connectivity

    The RT-AC51U Wireless Router includes a USB 2.0 connection which make it perfect for transferring files, attaching USB devices or setting up a shared printer. There are also five Ethernet ports for connecting your wired devices, whether it's your Smart TV or your PC.

    You'll be able to connect to your data wherever you go thanks to Asus AiCloud technology, which links to your home network. Access your home content from your iOS or Android smartphone, or through a web browser.

    Download Master allows you to download files even when your PC is turned off, which means you'll always have access to everything you want.

    Getting connected is easier than ever when you use the Asus RT-AC51U Wireless Router.
