First I would like to say that I didn't know how to format the proper title but below is the issue.
I have a router that connects to the ISP but in this router there X people connected, i know all of these devices. I even reviewed this cited below with only me connected.
The issue is as follow, the statics the router gives (ping/up/down/...) are not close to proper of what I am supposed to have. At first I thought its from the ISP, maybe an infrastructure issue, I still think it may be is/was but I decided to use a software to check something out. Its called selfishnet for whoever knows it. Now using this stats became real, what is supposed to be. So i started thinking what if someone in the area was connecting to the frame then again I checked the DHCP table of the router still nothing, just me. At this point I suppose two things (beside an ISP issue). Someone is on the frame all the time but is somehow not appearing in the dhcp table or some activity with the softwares i use is draining but i already checked that and there is nothing abnormal.
Maybe there is something I missed and should check, I apologize in advance I dont know much in the security field.
