This router has 2 x 5 dBi, fixed antennas. Antennas are key parts of wireless routers. They send and receive radio signals to make wireless connections. This router is 2.4 GHz capable. The 2.4GHz band refers to the portion of the radio spectrum between 2.400 and 2.4835 gigahertz. The 5 GHz band offers better noise immunity and less interference. It also has more available channels. The AC Wi-Fi router is backward compatible with older Wi-Fi devices that support 802.11a/b/g/n standards.

Real-world NBG6616 router speeds are lower than its theoretical maximum speed. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security.
