Slow download speed!

My normal download speed is 10 mb/s,
but with this Retribution update is updating at 3 KB/S! Can go lower to 500 - 700 BT/S - Bytes!!

GUYSSS I FOUND THE SOLUTION. If you tried all fixes, you should try it, i discovered it myself: device manager > network adapters, select your network adapter and select advanced and find “power saver mode” or like this, select it and disable it. my computer’s language is turkish so it can have different translation.
