Samsung S7-wifi calling not using an AP

[AC Question]

I have a main router and 2 access points in my house. Sprint's signal is not great inside my house so wifi calling is awesome for me. But I have just recently changed from an iphone 6 to a S7 and I noticed when connected to one of the AP's I did not have wifi calling ability. I was able to figure out that it is not listed as one of the wifi calling networks inside the wifi call settings. I have tried to find any place to adjust that but I cannot. Anyone know why it is doing this and what I can do to fix it? Thanks
