Lost Connection to Server

Hi, just an issue I’ve come across recently.

My brother and I play a lot of Overwatch together, however recently I’ve been noticing an issue. I get frequent lost connection to server errors, every time I play. My brother uses the same internet too, however he does not receive this at all. It’s very frustrating because I had been penalised for something that was not my fault. I was not purposely leaving games. I appreciate any help.

Thanks in advanced.

Which troubleshooting steps have you tried to resolve this?
