BTW I see that CC3000 is deprecated.

I don't know how complex your requirments are but the ESP8266 is dirt cheap and easy to use, connect rx and tx and send it AT commands (like a modem). In fact it has an on-board 8051 that can be re-programmed - unfortunatly not by PicBasic. There are a number of hobbyist ESP8266 web sites, once again goggle is your friend.
