Battlefield 4 Error you have been disconnected from the servers how I fixed this was to go in to my router and look for universal plug and play UNPNP and un check it. If you don't know how to get into your router in windows press start and in run type CMD this will bring up the command prompt next type ipconfig /all now look for your default gateway this should be your router ip address mine is 192.168.0.1.
Next in your internet browser type http://192.168.0.1 you should see the router log in page.
Check your router sticker for the log in details
After you log in look for UNPNP and un check this and click apply.
Hope this helps guys BF4 is awesome when you get to play it.
