I'm currently been having issues with my connection since patch 2.1 that makes endgame unplayable. I have checked my computer for Viruses and Malware, checked my cables, reset my router, checked my Ping with SE's NA Data center, checked my connection, eliminated some backround applications... did a ipconfig /flushdns... you name it. I even called my ISP(Verizon Fios) and went through nearly an hour or two of troubleshooting. I would like to mention also that past midnight EST my connection is 100% perfect up until around 5pm EST.. then the game becomes unplayable. I'm thinking this has to with SE's server and the latest updates they have done. I'm going to call SE on Monday but if anyone has found a solution if they have experienced this let me know.
