Turn a WiFi 7 Router into a 320Msps Software Defined Radio Receiver
Points and comments are a snapshot, not live.
A Wi-Fi 7 router's chipset is repurposed as a 320 Msps wideband SDR receiver.
The GitHub project turns a Gemtek W1700K router into a wideband SDR receiver. The MediaTek MT7996 radio captures 14-bit IQ at up to 320 Msps, streamed over 10 GbE via the Airoha AN7581 SoC. Custom firmware (ROM patch, WM, WA) is written entirely from reverse engineering, with no MediaTek code. The host displays live spectrum and waterfall in a browser, with controls for LO, sample rate, gain, and filter. Supported bands: 2.4, 5, and 6 GHz. The repository includes the platform OS, kernel driver, firmware, and host tools under MIT and GPL licenses.
What commenters are saying
Commenters are enthusiastic, calling the project a breakthrough for cost-sensitive SDR. One notes the whole platform costs under $100, whereas comparable 320 Msps gear previously required upper four-digit sums. Several point to a related ESP32-based SDR project by the same developer. Some debate whether AI assistance is evident in the writing style, but the general sentiment emphasizes the value of opening locked-down Wi-Fi hardware for general-purpose SDR use.
