Lag Issues on Xbox?

Basically title. I’m having lag issues (people “teleporting”, clipping through the ground, I’m missing shots but still get the kill, etc.). I’m sitting right next to my partner on PS5, as well as closer to our router, and he isn’t having lag issues, so I know it’s not my wifi. Is it an Xbox server thing, or?

Have those sorts of issues but on PS5, hardwired as well as wifi. still couldn’t find a fix even though I’m on my second PS5 that is one month old. Could it judt be a power outlet issue? Are both consoles plugged into a power strip?
