So I have a couple of BT Discs. I know the Ethernet port is used to set them up, but can I also use it to keep them network connected, or does the Disc need to pick up wifi from the router to then extend it (i.e. is the ethernet port redundant for connecting to the main router?)
I have an ethernet network throughout my house so I dont have an issue with extending a wired network, but I am trying to use the discs to get the best possible wifi network, and I would like to place the Disc outside of the range of the normal wifi (hence use the wired network for it to communicate with the router). Any tips? Having tried to use the ethernet connection with the Disc it doesnt seem to work well - I keep losing connection?
You refer to using the ethernet port to set the discs up, from that I presume that they are the black discs, in which case yes, you can use the ethernet port to provide a wired backhaul
They are both black discs. They weren't recieved together so have different BT brand on them.
Probably just a cosmetic difference
The black discs are known as Complete Wi-Fi discs, the white ones are known as Wholehome Wi-fi discs.
The two are not compatible with one another but as long as they are both Complete Wi-Fi discs then they should work.
Looking at BT shop, it appears that the Wholehome discs are now available in grey (just to add a little confusion), if you have one black disc and one grey disc then they will not function together
