Asus 4G-AC55U LTE Router Review

Asus offers the 4G-AC55U in December 2015,  which is a new LTE router for stationary use. The new 4G Router offers many connections and is supplied with a current WLAN 802.11ac radio module, allowing speeds of up to 867 Mbit/s via WLAN in the 5 GHz range. The integrated cellular modem could support peak up to 150 MBit/s in the downlink and up to 50 Mbit/s in the uplink with LTE networks, and UMTS and GSM are supported. The design is quite exceptional for a LTE router; there is a diamond pattern on the front and the radio antennas are designed visible clearly outside the housing.


With the Asus 4G-AC55U router, you can choose the Internet access via the mobile network (LTE, UMTS, GSM) or via an existing modem. For the mobile use, of course you need a SIM card (mini-SIM form factor) with a data plan, it does not matter whether it is a prepaid card or a contract card, the Asus 4G AC55U has no SIM lock and can be used with any tariff. If you want to use the router via an existing Internet connection, you need a modem (for example, a DSL or cable modem, depending on the connection). The Asus AC55U connects simply via the Gigabit WAN port to the modem, then the router acts as a pure Access Point.


According to the Asus official site, the 4G-AC55U could support LTE frequency bands at FDD Band 800 /1800 /2600Mhz and 4G TDD-LTE at 2500/2600MHz. Like other 4G LTE Router such as Huawei B890, 4G-AC55U is also backward with UMTS and GSM/GPRS networks.



The Asus AC55U 4G Router provides a very fast Wi-Fi connection compared with other models. The device transmits simultaneously to 2.4 GHz and 5 GHz on demand, thus reaching speeds of 300 + 786 MBit/s. Thus data-intensive applications such as UHD streams, online gaming and a NAS usage should be no problem. Alternatively, you can also use a four RJ45 Gigabit Ethernet ports on the back of the router for connecting devices with the Asus 4G AC55U. The wireless connection can be switched on and off on request with a switch on the back.


For the connection of a USB storage media, an USB 2.0 slot is available. So you can for example integrate an external hard drive in the network and retrieve content such as movies and photos directly on the smartphone or tablet. A printer can be integrated via USB to the network.
