I believe my router is called Cisco, it's a business router. but the problem doesn't seem to be internet related at all. I was able to un-install and re-install Destiny 2 on the same day, without any wifi or internet errors. And to further prove it's not my router, I was able to play on a different game's multiplayer while Destiny 2 was still downloading and got no errors, or lag. Then once it finished, I get back into the game to see that the problem is still there. It didn't start happening until two days ago, when steam installed this tiny 8mb patch to the game. I don't believe it's my router because I started the game off with this router, and played 47hrs on that same router. (Yes i'm still a beginner.) So, unless that 8mb patch made my router incompatible. I hope to see it fixed soon.
