wireless router connect to ADSL router

all the computers in my office are connect to a Hub/Switch, and the Switch is connect to a ADSL router(DSL-500G). And now i’m getting a wireless router(DIR-300) hopefully some of my wireless devices able to access to internet as well.
the question is, Can i just connect the wireless router to the switch without changing the ADSL router IP address?
Pse provide some details tips and helps on this matter.
The IP address for ADSL router is 10.1.1.1
and the wireless router IP is 192.168.0.1
How can i make them works?
Many thanks
