First of all, my WiFi is always on.
Why do you suspect that this network is owned by hackers?
Do you have any proof? If not well then I would very much doubt it being hackers.
If you do go to your local police station and report it.
Or if you want to trace it on your own:

You will need:
A PC or notebook running Windows with an Ethernet port.
A Linksys WRT54G or WRT54GL wifi router
OpenWRT, a free Linux operating system for the wifi router
X-WRT, a better web interface for OpenWRT
Kismet for OpenWRT
CIFS driver for OpenWRT
Wireshark ( a free program)
Putty for Windows, a free telnet/ssh shell for Windows.
With this setup, tracing a Wirless LAN can be done as follows: In a first step, the native software of the wifi router has to be replaced with OpenWRT, X-WRT, Kismet and a CIFS driver. Once the setup is running, Kismet is used on the router to collect all 802.11 wifi packets the router receives and to save them to a file. As there is not a lot of room on the router for the file it needs to be stored elsewhere. This is done connecting the router and a Windows PC with an Ethernet cable and by mounting a Windows directory on the router. No extra software is required on the Windows PC. On the wifi router the CIFS driver is used to mount the directory. The file Kismet creates in the shared directory can then be analyzed using Wireshark for Windows. The picture on the left shows how Wireshark decodes an 802.11 beacon frame recorded by Kismet.
