Ultra-fast mobile internet and ultra-fast Wi-Fi — in one!

Simply pop in a 4G LTE SIM card to the 4G-AC55U LTE router, and the built-in modem connects wirelessly to the internet via super-fast mobile broadband. You can enjoy up to 150Mbps downloads and 50Mbps uploads, with no worries about USB dongle compatibility. It can even connect to a cable modem if you just want to use a 4G LTE connection as a backup internet connection! With its 4X wider Wi-Fi coverage and concurrent 1167Mbps Wi-Fi speed, you can share the internet connection all around your home or office — perfect for locations where 4G LTE speeds are faster than conventional ADSL or cable broadband. Convenient and cable-free, 4G-AC55U will give you smoothly-streaming HD videos and fast file-sharing.

Blazingly-fast wireless performance

4G mobile broadband technology means you will enjoy 5X faster downloads and uploads than 3G HSPA+1. The latest 802.11ac 2-transmit, 2-receive (2X2) antenna design, provides up to 6X faster wireless speeds for brilliantly-fast HD video streaming, file transfers and more!

4X Wi-Fi coverage – no dead spot, no delay

You will enjoy lightening-fast 4G network speeds with 4G-AC55U’s external dual-band antenna and fine-tuned radio frequency design. This widens the Wi-Fi coverage by up to four times compared to other 4G LTE routers, giving phenomenal performance throughout your home3.

4G LTE signal strength indicator for easy installation

4G-AC55U makes it easy to find the best position for your router — simply use the signal strength indicator button to find the location with the strongest 4G LTE signal!

Detachable and upgradeable 4G LTE antennas

External mobile broadband antennas perform better than internal antennas. Indoors, the best 4G LTE reception is usually found near a window, but if this isn’t practical you can easily add an antenna extension cable thanks to the detachable antennas with their standard SMA jack connectors.

4G LTE and Gigabit Ethernet dual-WAN for interruption-free connections

In addition to its 4G LTE capability, 4G-AC55U has a dedicated Gigabit Ethernet WAN port that can be used as a backup wired internet connection that is activated when the 4G LTE connection fails (failover), and automatically switches back when service is restored (failback). This gives superb flexibility for business or home use — you need never be without an internet connection.

Advanced multi-layer security

With 4G-AC55U your home network is protected by a multi-layer security system.

1. MAC filter: Allows you to block one or more devices based on their MAC addresses.
2. Access control: Control the level of network access granted to any network device, for example blocking certain ports or internet services.
3. Keyword filter: Block access to undesirable websites based on keywords and apply these restrictions to specific network devices4
4. Advanced firewall: Firewall with Stateful Packet Inspection (SPI) protects against common web-based attacks and threats.

Easy 3-step Plug-n-Surf

It only takes three steps to get connected with 4G-AC55U:
1. Insert your 4G LTE SIM or micro-SIM card (not supplied) and turn on the 4G-AC55U. It will connect automatically to the appropriate mobile network.
2. Open a browser and follow the easy installation wizard to complete the setup.
3. You’re connected!

ASUSWRT puts you in control

With the easy-to-use ASUSWRT user interface, it’s easy to configure all 4G-AC55U’s advanced functions. It also has simple tools to keep tabs on your data allowance and actual usage, check what devices are connected to the network, configure user access controls and much more – all via an intuitive point-and-click graphical menu.

VPN Server and Client for Encrypted Remote Connection

With the virtual private network (VPN) server and VPN client, you can access your home network remotely or surf the internet with encryption, no need for paid VPN services or a dedicated VPN server.

Create your own personal cloud

ASUS AiCloud keeps you close to your data wherever and whenever you have an internet connection. It links your home network and online storage service, giving you access to your files using the AiCloud mobile app on your iOS, Android smartphones or via a personalized browser URL. You can share photos instantly to services like Facebook, Flickr or Dropbox directly from the AiCloud interface. Even better, AiCloud can be connected to another compatible router to expand your personal cloud even further.
