Ah, well have you checked the 'Allow intra-BSS communication' box in the wifi interface settings?

Nope, ticking that option fixed it.
Thanks so much. There are so many options in pfsense as a new user it is hard to figure everything out. I apologize, if that was an obvious solution, didn't mean to waste people's time.
Thank-you to everybody in this thread who tried to help me out.
