I recently installed the Qualcomm QCNCM865. Here are my observations:
On Linux:
- Bluetooth Audio: The connection can be unstable, but it seems more reliable when using AAC settings.
- System Stability: The device crashes during heavy uploads not downloads, though it handles large downloads without issues. I’m running kernel 6.11 R1 (rawhide), and the problems persist.
On Windows:
- Initial Setup: Bluetooth and internet didn’t work out of the box. I had to manually download and install the drivers through Device Manager by selecting them.
- Performance: After installing the drivers from the Microsoft repository, everything seems to be working fine. You can find the drivers here: Microsoft Update Catalog - FASTCONNECT 7800.
