Just have a look on the reviews of the adapter. The 5 and 4 start reviews might will have a clue how to connect it. But there are mostly 1 star reviews that it is not working.
Contacting support is a waste of time…
They will have no clue what you are talking about. You most likely will receive a canned answer, probably will advise to clear cache, reset your phone, router, etc.
Otherwise, I thought these adapters were made for fridges only. Anyhow, they are quite useless there as well. (I managed to connect mine, but the capabilities are shockingly poor.)
