OKW has broadband available in all of the villas- costs is $9.95 for a 24 hour period. OKW has no WiFi available.
All of the WDW DVC resorts have broadband (same as OKW). BCV does have a few WiFI hotspots - I think the charges are similar - but no WiFi in the villas. Some members have connected wireless routers to the broadband network and have created their own wireless connections in their villas.
