YEEEEEEEEEEEEEEESSSSSSSSSSSSSSS!!!!!!!!!! I did it! I found out what was causing my problem of not seeing any opponents. Turns out it's my router's firewall in conjunction with a spotty UPnP that causes the problems in MK7 but not in SSFIV. Adding the 3DS to the DMZ function of my router finally did the trick. FINALLY!!! Haha, now I'm gonna kick your ass, Nate!
