I have my network bandwidth eaten up totally. Whenever I connect my network, without any application being opened it is always full.
I have prepared report of iftop, nethogs and network system monitor.
My host IP is 192.168.1.203 and all the rest are not known though I have tried to pin 192.168.1.105, it doesn't reply.
If possible I would like to block the most disturbing IP which is 192.168.1.105 to block it. but don't know how.
