HG659 connection logs? (trying to solve a crime)

A friend of mine had a back window smashed in at night, nothing was stolen, but the suspicion is that it was someone they know well. Well enough so that they have the wifi stored on their phone and it might have auto-connected at that time of night.

I was trying to find connection logs for them through the web interface of the HG659, but the only logs I could find were system-level stuff. My Netgear router logs the MAC address + IP address whenever an IP gets assigned to a device. Does the HG659 log that kind of data in some way and if so, how can I get to that data?

Thanks a lot for your help!
