Answer 2

Check the security log on your wireless router.  If you had logging enabled on your wireless router, you should already have this information.

Answer 3

The easy way would go to www.snapfiles.com and download angry ip, and run the small program and it scans all the ips on your network and shows all the ips that are being used

good luck
