Had mine a couple of months now. Not impressed so back to HG612.
Too many reliability issues - overheating and restarting. Hopefully a firmware update will sort the issues because the Wireless was very good.
Well I tried our free Smart Hub for 5 days a couple of weeks ago on our ADSL2+ connection. It was to originally to set it up ready for our FTTP order to be installed (still waiting BTW)
But the issues we had was the latency was a lot higher, it was stable for 3 days with absolutely no issues at all, then came all the disconnects every few mins to every hour.
I got that fed up of it so I went back to my HH4 and put the Smart Hub back in its box.
I never had any heat issues or any constant rebooting of the hub, only the dropping of the connection.
There was some cosmetic issue with the GUI and some of the information displaying wrong information etc, but apart from that it wasn't that bad.
I am sure it will be fine when the engineers come out to do our external and internal work.
But in my eyes the Smart Hub isn't that smart on ADSLx.
