As long as you already have ADSL, you should be able to connect it to ADSL line as well as PC, and it should sync with exchange, altho' not connect to Net. You should then be able to login to it and see its stats. User/pwd usually "admin/admin" or maybe one of them is "sky".
I was sent a Sky locked router in error, when I thought I bought a generic Netgear, and it sync'ed OK with my Orange line and showed my normal stats.
