A factory reset would have been a better option, as that is the only way to clear the DHCP table.
It will delete any contacts you have entered in the phone, however, the contact list can be backed up before resetting and restored afterwards. It will also require the DV handset to be registered to the hub again.
You don't need a manual, there is very little configuration you can do with the Hub and the menu options are straightforward and intuitive.
This is interesting. I've just connected up the Smart Hub 2 in anticipation of DV next week. (Sad to see myTP Link VR400 go, it's been great) I have exactly the same devices appearing as @clique-al in my list. Could this be equipment they use for testing refurb hubs?
if that does not mean anything to you then I would factory reset the hub by pressing the recessed button on the back of hub and hold for 20/30 secs until hub lights flash then reboot hub and should be completely clear
if you have a lot of wifi devices I would change the hub SSID to that of your tplink and also use the existing wireless password and that way your wifi devices will connect as if there had been no change
@imjolly Thanks for that. I have just Factory Reset the Hub and it is now completely clear. Whatever the reason these devices were there it now makes it easier to keep a track of all the devices that should be there.
