I gave my next door neighbour my wireless password in an emergency when his was off. Today I logged in to my router/hub and discovered that there are 11 device connected. Counting them up it is possible by counting my Printer, Laptop, Desktop, Laptop, Phone, Tablet, Wife’s Tablet etc. It is impossible to identify them all, one is shown as Unknown, so I do not know if my neighbour is still linked in. I was reading a magazine article which said to switch the items off in turn to identify them, which does not work they are still all showing. My understanding is that there is a lease period with connected device and therefore the magazine article is incorrect, they would still show. Can anyone please clarify this for me.
