Since I'm using wi-fi I've got "monitor wi-fi connections" switched on in Bitdefender Internet Security 2013. Looking at the firewall events the WAN IP address of my router appears every 20 minutes (plus a few seconds) the whole time my laptop is connected to the internet. There's another IP address though that appears at random intervals which begins with a 10. I understand that this means it's a private network address so I was just wondering if it's me as the address is always the same or if someone else is accessing my router wirelessly.
Any help with this is greatly appreciated.
