GL-AR300M16 is a mini travel router for working professionals and a programmable gateway for DIY hobbyists. Larger Storage and Extendibility The router with storage of 128MB RAM and 16MB Nor Flash, can be further extended using external USB sticks. There are 2 Ethernet ports, 1 UART, and 1 GPIO available for hardware DIY. It is an ideal portable gateway for IoT development. Wi-Fi Converter Wi-Fi is extremely popular but still may not be available anywhere. If you are still using a wired network at hotels or cafes, this mini router is able to convert it to a wireless network for sharing Wi-Fi with all your devices. Even in places like cafes or restaurants with Wi-Fi, it is not good to expose your devices to the public network directly. This router converts a public Wi-Fi to your own Wi-Fi with a firewall and then works as an agent for securer surfing. The agent connects all your devices when switching to a new Wi-Fi. You dont have to input passwords for each of your devices. The router is also able to convert your phone tethering, or 3G/4G USB modems into private Wi-Fi. Portable Travel Mate: The router is lightweight, pocket friendly, and portable. It can be plugged into any laptops, power banks, or 5V DC adapters for power supply. Open Source and Programmable OpenWRT is pre-installed and backed with a repository of 4000+ software packages. Pre-installed with an OpenVPN client, it works with 30+ VPN service providers.
