Packet loss

Hello , I am a avid gamer and recently I have been receiving massive amounts of packet loss. This causes major lag and latency issues when I game and it’s very frustrating. This issue has been happening for weeks now. I’ve contacted the support team several times and all of them have no idea how to help me. I live in south Florida Tamarac area. If anyone else is having this issue please speak up so maybe Comcast could help us.
