D-Link DSL-604+ Wireless ADSL Router – Support Forum

DSL 604+ Can I just use it like a wireless router without ADSL connection? [D-Link DSL-604+ Wireless ADSL Router - 104294]

Had this many years but recently moved house and joined Vrigin Cable Broadband. Virgin wanted GBP40 for a Wireless Router, but I was wondering if I can use this simply like a Wireless router to save me a bit of money. Any help would be greatly appreciated.
