White is also dual band. The blue one looks similar to the black one (oldest) and looks lot uglier than white. But somehow it's the latest one, probably to match their color and design with the STB, tho even the STB looks ugly. However, the blue one has 4 gigabit RJ45 ports instead of 3 on the white one, so that can be an advantage. The WiFi is still terrible, so if you want anything above 250mbps wirelessly, get a better router, turn off DHCP mode on that and connect it to the Jio router using Ethernet.
