What does the term “Connected WLAN Clients” mean when stated in my broadband account with www.my3.ie ? “Whenever I check it there are one or two connected WLAN clients using it? Who are they and why are they non-consensually connected to my personal broadband account. The MAC ADDRESS that is given for them is 4E:15:23:5B:02:1F. Where are they located and what does it all mean for me?
