Monitor when someone connects to wifi

0

Is there any way to monitor when someone else connects to my wifi? My wifi is OK, but sometimes it dips drastically. I only notice this after the fact. I would like to know exactly when someone is connecting. I only know about the "arp -a" command.

Thanks for any help.

You really should secure your router instead of searching for a WiFi thief.

PS: I'll read the content in your link, too. Sounds pretty simple from what I've read so far.

arp -a doesn't exactly help you with this kind of topic. You might use Wireshark and capture on a supported wireless adapter on the same channel your wifi is using (supported means that you'll have to use Airpcap adapters if you're running Windows). Then look for association requests with successful association responses - if you find any, you have evidence of someone connecting to your access point.
