I am assuming you have got a shub. If the shub is in router mode go to
http://192.168.0.1 and click on advanced setting and I think you want the connection tab. We are after the power levels and stuff from that page and you can do a copy and paste. If you are using your own router and the shub is in modem mode go to
http://192.168.100.1
I am assuming your pc is wired and the laptops are wireless?
