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

ASUS 4G-AC55U is the fastest 4G LTE router you can buy! Simply pop in a 4G LTE SIM card, and the built-in modem connects wirelessly to the internet via super-fast mobile broadband. You can enjoy up to 150 Mbps downloads and 50 Mbps 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 1167 Mbps 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 — anywhere.
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 home.
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 syste..
