The web UI would go unreachable, FTL would silently die, and DHCP would stop assigning addresses. The only fix I had was unplugging and replugging the device. Not ideal for something that sits in the middle of your network, especially when you live with other people.</p> <p>This post covers how I diagnosed the issue and hardened the setup so that transient failures recover automatically rather than taking down the network.</p>https://nicoleman0.github.io/blog-site/posts/bluetooth-dualboot/Mon, 02 Mar 2026 00:00:00 +0000https://nicoleman0.github.io/blog-site/posts/bluetooth-dualboot/<p>If you dual boot Linux and Windows and share Bluetooth devices between them, you&rsquo;ve probably hit this annoying issue: the speakers connect fine on one OS, and then after switching, they refuse to pair on the other.</p> <p>When you pair a Bluetooth device, a link key is generated and stored on both the host and the device. The problem is that both Windows and Linux see the same physical Bluetooth adapter — same MAC address — but they don&rsquo;t share their key stores. So when you pair on Linux, it writes a new key to the device. Boot into Windows, and Windows has a stale key that no longer matches. Pair on Windows, and now Linux is the one with the stale key.</p>
