The 1 x 2 dBi, RP-SMA antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. 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. Older routers have a more limited range than newer Wi-Fi standards. So, they are less suitable for larger homes or offices. Real-world NBG4115 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. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
