Cant Connect to any battlefield servers, get Booted after squad creation.

Hi, I've bought BF5, BF1, and BF4 and I'm not able to play on any of the servers sometimes. I'm playing from Norwich university with an amazing internet connection but still is not letting me play. I was able to last night but now I'm not able to again. this is how it normally happens. I've changed my DNS to Google, and I've uninstalled bigfoot killer internet to no avail. I've uninstalled the game and it not working as well. I've checked drivers, internet speed tests tons of * but the game will not let me play. I'm able to do single-player fine and get into a squad but after that, I'm not able to play it just boots me back to the main menu with no explanation. some times it will say EA connection time out check internet but my speed is 500MB's upload and download so I don't know what's up. I've connected to servers with 20 ping and this internet without anything happening. I'm sick of this. Sometimes I'm able to randomly play and most times I'm not able to. Please please help me. I would like to see if i can check my connection and such i just want to play the game.
