I seem to have an issue with the range of the 5GHz channel on my SmartHub 6A that's only started in the past couple of days.
I have separated out the 2.4 and 5GHz channels, and previously have had no issues with devices connecting to the 5GHz channel. However, a couple of days ago I noticed that my devices were no longer connected to the WiFi. I tried resetting the hub, tried using different WiFi modes and channels for the 5GHz channel, but the devices still weren't connecting. I've found that if I'm right next to the router, the devices connect with no issue (this is true for multiple devices, i.e. phone and laptop) and the internet connection works, however as soon as I move away from the router (even just a few steps) I'm no longer able to connect to the 5GHz channel.
There is no issue with the 2.4GHz channel, only the 5GHz channel.
Has anyone else encountered this issue, or is it possible that the hub itself has developed a fault?
Its quite possible that either the internal 5GHz wireless module has developed a fault, or the internal aerial connection to the module has become disconnected, possible a bad soldered internal link.
If you have tried removing the power from the home hub for a short while, and also tried a full factory reset of the home hub, then you will have to ask BT to swap it out with another one.
