I have just installed a hybrid connect device, part of my renewed broadband contract. It all appears to function as it should. When I disconnect the BT hub input cable to test, as expected the hybrid connect's signal strength bars turn white and the hub glows solid purple. But there is no transparent connection (it takes several minutes in any case before anything happens with the hybrid connect). My laptop then says I have no internet connection, and if I go to a new web page, my browser (Firefox) says I need to log into this network. 'This network' is EE, and I get the log-in page, but trying to log in doesn't get me any further. And then when I reconnect the hub, I have to switch off its power, and switch off the hybrid connect, before the hub will restart and reconnect (it just stays solid purple when the hub input cable is reconnected). I also have to stop the laptop from trying to connect to EE wifi and tell it to connect to the BT signal. This is far from a transparent switchover (and disconnecting the BT input signal cable is exactly the same as a fault on the line), in either direction. My new contract doesn't start for two days, but that is only paperwork, and a hybrid connect is supposed to work before broadband is connected (ie, before the contract starts). I don't think this is a very useful item.
The hybrid connect takes several minutes before it kicks in on failure of the broadband signal, likewise several minutes before the router switches back, this is by design. It is not intended to be a seamless transfer.
Several minutes - not twenty! Nor should one have to log in to EE wi-fi, which is what my Firefox told me - I can't log in to that. I don't have an EE wi-fi account, nor should I need to, if this is an automatic transfer from BT. Supposed to be a transparent takeover, which means I shouldn't have to do anything but wait. This is far from the case.
