Why Is My WiFi Slow on Fedora? The Culprit Is Bluetooth (Intel CNVi Antenna Sharing)
In the same room, on the same WiFi: a Windows 10 machine pulled 50 Mbps while my Fedora laptop was stuck at 2-3 Mbps. Driver, signal, channel, background downloads — all clean. Pinging my own modem showed the problem wasn't out on the internet but between my laptop and the modem; the cause was Bluetooth. I proved it with measurements, and I walk through the two fixes that failed and the mistakes I made building the speed test.
