W1700K SDR captures up to 320 Msps of 14-bit complex IQ signals from the MT7996 radio chip in a Gemtek Wi-Fi 7 router and sends them to a Linux host. It supports the 2.4, 5, and 6 GHz bands, provides browser-based spectrum and receiver controls, and disables transmission in its custom firmware. Installation requires a serial adapter and 10GbE connection. It replaces the existing operating system and backs up NAND, but does not supply a flashing tool for restoration. These figures come from project documentation; independent performance validation was not obtained.
