cbr40 connect to wireless printer Epson workforce 845

To respond to reply that the workforce845 connects to the router. Yes I entered all correct info into printer per epson web site 5 or six times w/ same result. Ran network check security key / password check failed they are correct  ip adress unchecked / detailed ip setup check unchecked. The printer generates a pin code which it says to enter into the computer within two minutes. were would you enter that pincode. also ran Microsoft check and all is correct. printer is default . I'm not a techy. could it be ip address ?
