Someone Or Something Trying To Connect To My Private Network ? (Help)

Hi, I'm new on cybrary.it , nice to meet you all ! While exploring my router's configuration I came across a log utility. Sure thing, I decided to check it out and found that "A device failed to connect to SSID (name of my SSID) because it provided incorrect login information". The thing is, while looking deeper, I found out that it happened a LOT, pretty much every day for the last week.( I did not check farther than that..) My question is , can someone please tell me if that is someone manually trying to connect to my wifi or if something else could be doing that automatically ? Or how to find out ? Also, if it's indeed someone ( like a neighbor..) is there a way to identify him ? \[Here is an example of the logs..\] 2016-02-16 21:44:22 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 21:45:16 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 21:46:13 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 22:28:26 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 22:36:33 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 22:51:08 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 22:51:43 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 23:00:57 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 23:01:54 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 23:02:52 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 23:11:09 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. 2016-02-16 23:12:07 ERR WIFI A device failed to connect to SSID (lil.family) because it provided incorrect login information. Lock down your router...the devices Internet facing IP is always being scanned. The problem is that your Internet facing web interface is enabled allowing someone to view the logon page form an external device.

If someone is connected, then you can use Nmap for gathering more information. Set promiscuous mode on and start gathering data using Wireshark for potential lawsuit. You can try Moocherhunter [http://securitystartshere.org/page-training-oswa-assistant.htm#moocherhunter](http://securitystartshere.org/page-training-oswa-assistant.htm#moocherhunter) or other advanced ways to triangulate position using radio antennas.
