Re: 2.4GHZ and 5GHZ Bands BT Smart Hub 2

Go to solution

Im not wrong - if you go to a fibre/ digital bt line it doesn’t matter what router you have, your analogue intruder/monitor alarm will not be compatible with the digital line and you no longer have copper phone line, so no call from the system and the system will also keep advising you that you have lost the landline. 
BT are having to go to Parliament this Autumn to explain what they are planning to to about the matter and since the matter blew up they have announced they will be delaying the Digital system for those who still require a copper phone line for their monitoring system. 
Im no expert on this stuff, just had to learn fast!

The green socket at the rear of the hub performs exactly the same function as your copper master socket.

It does matter what router you have, Digital Voice will only work with the BT Smart Hub 2

The alarm companies have been aware that the PSTN will be switched off in 2025 for a number of years.

Hi, I realise this thread is very old, however I got my SH2 delivered today and have not been able to connect any of the devices that need 2.4g, despite having firmware version v0.37.00.07084-BT

 

Is there anything I am missing? I will probably be returning the hub this week if this is not solved.

Firmware version is totally irrelevant, the SH2 transmits both bands.

Temporarily turn off the 5Ghz signal and then turn it back on again once the devices have connected.

@the-andreea Login to the router Advanced Settings, turn off the 5Ghz band. Connect your 2.4Ghz devices. Once connected you should be able to turn the 5Ghz band back on and 2.4Ghz devices remain connected.

If you have read forum posts try disabling the 5ghz network in hub and then see if you can get devices to connect to 2.4ghz network. Once connected then re-enable the 4ghz network

The reason for this is explained below



It's the device you're using for setup that needs to be 2.4Ghz - the coexisting 5Ghz network doesn't actually matter. The crappy device is listening for packets broadcast on the physical layer to tell it the SSID and password, so the phone has to be on that band to send them. Which is a problem for iPhones that don't let you specify the band, so the fix is to turn off 5Ghz, not because the device cares, but to force the phone to use 2.4.

I.e, the devices are connecting in ad-hoc mode rather than via the router.

Thank you, still a lot to learn. One device sorted, one still not playing ball - will try again tomorrow.

Yes, sorry, after posting my question I realised the 98 pages were all related to the same thread, and started reading through them. I had initially thought there were 98 pages of different discussions.

Of course all of this could be easily avoided if the "crappy router" allowed users of "crappy devices" to split the wifi bands.
