Constantly disconnecting during online multiplayer

Bugs I've been experiencing since the June update. Constant disconnections during online or multiplayer events. This occurs in any part of the weekend, practice, quali or race and will occur on or off track. Usually preceded by a connecting to online services prompt at the top left of screen or chat disconnected prompt. This make playing online pointless as the screen will turn black while the game runs in the background totalling your car, lap, race etc. when it reconnects properly you've been dumped into the lobby and none of the human players are there anymore. Hope you can find a resolve as I was loving the game up untill the last update. Thanks and all the very best, Ross
