Resxt yeah it's kind of a jus server wide thing jus doesn't make sense since me and him play on the same wifi and I only got the issues. How d I fix the unstableness tho

I play plutonium bo2 and bo1 with my brother and for some reason his connection is smooth and my connection goes between like 40 to 50 ping to 200 to 250 ping would anyone know why's that.
