It’s probably the adapter since it’s close to the refrigerator and I cannot use another socket cause the telephone line is there. I’m curious though cause at first it worked everywhere fine.

@Solla-topee thanks for replying it's the 226 but it works now although a lot closer and with half the speed.

So it worked fine for 15-20 mins and then suddenly unpaired. I tried other sockets but it only pairs when it's in the same room as the adapter now...
