Firmware for the TP-Link TD-8901N router, version 2 hardware, with 4port in the name indicating a build for the four-LAN-port variant. The 1.35 MB ZIP may contain either a web upgrade file or a raw flash image, so inspect it before deciding how to load it. Raw images are written with a programmer to restore a router that will not boot. Confirm the hardware version on the device label, and back up the existing flash, which holds the MAC address and radio calibration data.
