Bandwidth latency issue bv5

Husband and I have always been able to play in the same server on BV5 using the same internet, but recently when I try to join his game it will kick him out and tell me there isn’t enough bandwidth or a problem with the latency. We are able to play different online games at the same time without any issues, so I don’t believe it’s an actual internet issue. Is this a battlefield issue all of a sudden? Does anyone know how we can fix it?
