I have recently upgraded from 'copper wire' to Full Fibre and TalkTalk sent me another WiFi hub which is identical to my existing WiFi hub but with an older firmware version.
The old version was SG4K100208 and its replacement is SG4K100174.
Why is this?

Hi @JohnIsard
Both the 5364 (Hub 1) & 5464 (Hub 2) run the same firmware & should now be on V208.

@JohnIsard the versions update automatically. Your router will also update as time goes. Should you encounter faults please reach out for assistance.

This has not answered my question. Why does my new WiFi hub have an older Firmware version?
According to another post on here, Firmware Version .......174 actually has some issues.

Further to my last post, I notice that they aren't identical Sagemcom routers because the later one has a VoIP phone socket. Furthermore hey have different Device Versions, the old one is "FAST 5364-3.T8" and its replacement is "FAST 5464-2.T4"
