Issue joining a friend on multiplayer.
I have a particular friend that I keep having connectivity issues with. One of us will lose connection to host or we can't join eachother's lobby. If we close app and try again, the issue will be fine for a little while then reoccur. We have the same ISP and didn't have this issue until about a month or two ago. This issue only occurs this frequently when I play with this particular friend, everyone else can join our lobbies and play with us just fine.
I have the original ps4, my download is usually 50, upload close to 10. My ps4 is hardwired.
Can assigning my ps4 it's own IP address possibly fix this issue?
