I had my phone (s21 Ultra) since 2021. Up until recently (as of today), all my apps just won't connect with my wifi with the exception of YouTube. However, my other apps like discord are having problems. My google browser do work, but accessing a browser link will either take decades or time out (which is always the latter). Any time I switch back to using mobile data, my device is running like nothing happened, unlike my wifi connection. It's having a stroke. I've tried everything to resolve this issue. Reset wifi, turning on airplane mode, restarting phone, restarting the router, clearing cache partition, etc. Nothing has been working for me, you guys have any solutions?
Update: So it turns out it's not my device after all. It's most likely the router, I don't know what's up with it. Turns out, my desktop, including my parent's devices couldn't connect. So we'll most likely have our technician over to see what's going on
