Connection Issue (PS4)

I been playing OW with my parents’ WIFI since I first the game (a year & a half ago) running decently minus some random disconnections, but since the Ashe update I can’t enter the game. Every time I try, I get to “Entering game…” part, then I get disconnected from the server (LC-202). Few days after, I tried again and no luck. I decided to use my phone’s mobile hotspot and I was able to get through. The phone’s connection was good, but has some 1-2 second lag spikes here and there. My question is why did this happen and how can I possibly fix it?

There are a variety of possible causes to cause a disconnection. Please try these steps first (including advanced troubleshooting steps) to resolve any common issues that could occur on your end.
