Note: Specific version numbers evolve, but the key capability changes are listed below.
For years, the most common complaint regarding the Smart Hub 2 was the "Smart Setup" feature. Intended to help guests connect easily, it often caused headaches for devices like printers, smart home hubs (Hue, Alexa), and older laptops, trapping them in a "connected but no internet" loop.
Recent firmware updates have aggressively refined how Smart Setup handles handshakes. The latest firmware is much better at recognizing "dumb" devices that just need a local connection without signing into a captive portal. While the option to disable Smart Setup still exists (and remains the pro recommendation), the firmware is now far less likely to break your smart home ecosystem out of the box.
Crucial Warning: Unplugging the router does not guarantee you get the latest firmware immediately. BT’s rollout depends on your unique Hub serial number and your telephone exchange area. You might be scheduled to receive the update next week.
If you are stuck on an old firmware version (e.g., SG4B1000 or earlier pre-2024 versions) and cannot get the latest, consider these issues:
Fix: Remove all discs from the hub’s list (under Wi-Fi → Whole Home), then re-pair each disc via WPS. The new firmware uses a different backhaul channel.
The current latest firmware reported for the BT Smart Hub 2 is v0.45.00.08028-BT (observed as of late March 2025). Because BT uses a staged rollout based on line numbers, some users may still be on previous versions, such as v0.37.00.07084-BT. Firmware Update Mechanism
BT Smart Hub 2 updates are primarily automatic and managed remotely by BT.
Automatic Rollouts: BT pushes updates when they are deemed stable. These often happen overnight; a sudden reboot or a change in the color of the Hub Manager's interface (e.g., from blue to grey) is a common sign of a recent update.

Support Lifecycle: BT has committed to a minimum support period for the Smart Hub 2 of 10 years from its May 2018 launch, ensuring security fixes and critical updates until at least 2028. How to Check Your Current Version latest firmware bt smart hub 2
