I tried to use Wireshark to get some information but I don't know enough to be successful with it. Without going into details, though, when I filtered using one of the MAC addresses I did see communications with our HP printer and that seems strange. Does anyone experiencing this problem not have a HP printer?
Also, if we all post the information we get and if any of us get the same MAC address then that is essential proof that something is not right. So the following are the devices I have seen. The following are the name, the manufacturer, the model and the MAC id for the devices I have seen in my system.
