Subnetwork off of wireless network

I have three Windows XP based computers and 2 printers on a wireless
network that works great in terns of file sharing, printer access, and
internet access. The Cisco router gets its internet source from a DSL
modem.

My home owner's association (HOA) has made available a fast wireless
connection and I would like to replace the DSL modem with the wireless
signal. Can I do that and still maintain my wireless network? I'd like
each computer to access the internet (and my other computers and
printers) through my wireless router and not directly access the home
owner's association wireless signal. How can I make the HOA's wireless
connection the input to my router?

Thanks.
