I just asked a question I think someone else has access to my wireless network. What next?. I have changed wireless security to WPA2, changed the password, disabled file sharing etc as =suggested in the answers. I even restarted my modem to that the DCHP leases expire. (Being a old modem, there is no option, at least from what can see, to reset leases)
Now, out of curiosity I downloaded Wireshark to see what is really happening on my network.
I still see 192.168.1.6 doing something on the network. Worse, I see my machine, 192.168.1.2 talking to it!
- How is this possible? The modem's DCHP leases say there is no 192.168.1.6.
- Could it be that my Mac somehow remembers a old address and tries to connect to it? Then why is there an response?
- Why would my mac connect at all? File sharing is off. Web sharing is off. Is this something to worry about or am I freaking out without reason?
