Dear all. I am trying to install smart switches using TuyaSmart from my mobile. The instructions with the switches say to switch off the 5GHz on my Virgin Smart Hub as they only work on 2.4GHz. This I have done through 192.168.0.1 on my browser, but then Tuya comes back with 'Network error' and nothing on WiFi can get onto the internet through the 2.4GHz connection.
I have checked several ways, and the smart switches are being picked up on 2.4, as they are showing on the phone. However, the phone won't register them centrally as 2.4GHz has no internet connection for the phone (so it says). I am aware of the option of changing the name of the 2.4GHz connection, but am not convinced that would bring back the internet.
Many wifi problems on the VM Hub3 are caused by (1) smart wifi having channel optimisation enabled, and (2) it Auto-assigning the same ssid “name” to its 2.4 & 5 GHz frequency networks. So the first job if you haven't already is to change these:-
Access your Hub by navigating to 192.168.0.1 (or 192.168.100.1) in your browser
Login with the default login info (it’s on the sticker on the base/drawer of Hub) unless you've already updated it !
Once logged in, go to “Smart Wifi” and - DISABLE channel optimisation
Then go to Advanced Settings > Wireless > Security
Under “Wireless Frequency 2.4GHz” - change the wifi Network Name (SSID) in the box to summat you like... xxxxx2G - and also the wifi password (network key) to one you like and will remember!
Repeat this procedure for the “Wireless Frequency 5GHz” (call it xxxxx5G to distinguish it) use the same password to keep it simple.
click on.. APPLY CHANGES, Log out and reboot the Hub3
Now all your devices should “see” the 2 individual renamed networks in your list of available networks and so you can connect to just the one of your choice. The 5GHz one is usually best and more stable and subject to less interference. Its range may be less than the 2.4 one though - which some devices like yours can only use. See if that helps. If not, You can always reset it back with a pinhole reset.
