  • •The Gemtek W1700K router can be repurposed as a software-defined radio receiver.
  • •The modification allows for real-time data capture and visualization at 320 Msps.
  • •The project is open-source and does not utilize MediaTek's original firmware.

The Gemtek W1700K Wi-Fi 7 router, utilizing the MediaTek MT7996 radio chip, has been modified to function as a software-defined radio (SDR) receiver. This modification allows the device to capture raw 14-bit IQ data at speeds up to 320 Msps, streaming it over Ethernet to a Linux host. Users can visualize the data in real-time using a web interface. The firmware used for this transformation is entirely custom and does not rely on MediaTek's original code. The project is open-source, with installation requiring specific hardware and software prerequisites. However, the firmware is receive-only, meaning it does not support transmission capabilities. There are no reported vulnerabilities or active exploits associated with this modification, and it appears to be a legitimate use of the hardware rather than a security threat.
