Samsung Smart TV not connected to Xfinity Wifi

​My Samsung Smart TV won’t connect to my Xfinity Wifi. I just moved and have Xfinity Wifi only. The Samsung TV sees the wifi but won’t connect to it.. and yes, the password is correct. I’ve gone through a complete reset of the Samsung TV with Samsung Cust Suppt and still not working. Any advice from Xfinity forums? All other smart devices have connected fine. I’m at a loss. ​
