I got a new modem so my router could use more wifi. When i set everything up and turned on my xbox it would only use 30mb/s peak. Before the change it would go up to 200mb/s and no my router isnt outputting a weak signal as its currently outputting 400mb/s with only a few devices on it. My old xbox 1 s also has the same issue but i just assumed it was because it was old. Help pls.
