ISE Labs research into embedded devices, we looked at Tendas AC15 AC1900 Smart Dual-band Gigabit Wi-Fi Router. During our research efforts, we tested the router running its then-latest firmware version 15.03.05.19.19. While they have recently removed this version from official circulation, we would like to mention that Tenda has not updated their firmware since 2017. The 2019 firmware version is still available to download from Tenda’s US website.”]
