Zyxel's AMG1302-T11C is a router with a built-in modem. A router is a device to which other devices are connected (eg computer, mobile, TV) either wirelessly or by cable, and to which it shares access to the Internet. Access to the Internet is obtained through the modem that is integrated. It supports ADSL2+, which is the most common internet connection technology, but older than VDSL2. It offers data download and upload speeds of up to 24 Mbit/s and 1.4 Mbit/s respectively. Corresponding connection technology is required from the provider. It is Wi‑Fi generation 4, an older generation that is recommended for use with few devices and for applications that do not require high speeds. It emits a signal at one frequency, 2.4Ghz, which offers a lower speed than those that emit 2 (dual) or 3 (tri band) frequencies. The 2.4Ghz frequency is the most widespread and has a long range. The device has the ability to configure a VPN (Virtual Private Network) so that traffic from all devices on our network passes through it. The VPN acts as an intermediary between us and the rest of the internet, allowing us to give the impression that we are geographically located in another country and the pages we visit see the VPN address as a visitor and not ours. This provides us with anonymity and access to geo-restricted content. VPN services are usually paid with a subscription. It has SPI firewall, a mechanism that controls data traffic for patterns of known types of attacks (eg DDoS). With MAC address filtering, it allows specific devices to connect based on their unique MAC address, blocking any device with a MAC address that is not set as acceptable.
