Review on 🔌 FebSmart FS-AC86BT: High-Speed Wireless AC 1200Mbps PCIe Wi-Fi Bluetooth Adapter for Windows Server, 7, 8, 8.1, 10 - Dual-Band 2.4GHz 300Mbps or 5GHz 867Mbps - Desktop PCs by Jason Flippen

Claimed to be compatible with Linux using the "ATH10K" driver. That's technically correct. It works properly under ATH10K and connects to my WiFi networks. However, there seem to be some compatibility issues with UFW firewall software. When I enabled my firewall and installed the driver, my desktop randomly doesn't start up about 3/10 times. I will not disable my firewall to use the wireless adapter. I spent 4 weeks troubleshooting to give the product a try by reading the Debian support pages and the FebSmart website. This caused me a number of errors in my work. I don't have this problem with any other device. I ended up returning the product and switching to a TPlink branded device recommended by Debian Wiki. I don't want to say that this product is bad, it was fully functional on Windows 10. However, I cannot give more than 3/5 stars because I feel the ATH10K driver's promotion on the product page was just overdone. proven hardware and software compatibility. If you have Windows then this product will most likely suit you and I would recommend it as a good buy. If you use a different operating system, I recommend that you first take a look at the operating instructions before purchasing.
