How to track usage on wireless

[sonky]

Hi. Is it possible to see if someone used my wireless yesterday? We have had a break in, and was wondering if I can track if someone went onto internet on Guest access? If so how do I check .....

You visit your stats to see if there is DNS activity and domains on that day your devices didn't cause with normal DNS traffic.

And if you had logging enabled in your router, you may see something in your router logs.
