Well that makes no sense as an engineering reason, as illustrated perfectly by Keith's example. Each user has a different RF situation in their locality, making BT's restriction entirely inappropriate and very myopic. It has deliberately made the HH6 worse than its hardware capability allows.
Perhaps this needs to be fed back to BT developers. Someone made an erroneous engineering decision, and it should be corrected.
The claim by BT Support that overlapping channels cause Wifi dropouts is quite ridiculous anyhow. Yes, overlapping channel will cause interference which may interfere with range and speed. The issue that the smart hub has is that the 2.4 GHz radio is unstable. I had my Laptop and phone immediately next to the router and the 2.4 GHz wifi disappeared completely. As I said before, get a decent 3rd party router and you will be in a happier place.
