Constant problem with network synchronization

I was at 6 star in H2H. My network was stable as it was showing in my mobile and other apps, but FC Mobile showed synchronization error. I was relegated to 1 star, even lost matches to 108 and 109, myself being 115. I usually even win with 116 but I lost to those low ovrs. Even if I consider them good, I could never lose 3-0 or 4-0.

Do something about this lag and network synchronize.
