Lag spikes on Xbox S

[#1]

So I don’t know if they are called lag spikes. But when I’m playing fifa or over watch on my Xbox. The game freezes for a split second then rapidly speeds up. For the second I’ve missed. It’s not an Xbox fault is obvisouly to do with the router/broadband. Every other device seems fine all over the house. Does anyone have a fox for this either through Xbox settings or logging into the router? I’ve already switched off 2.4ghz and just use 5ghz.

Thank you
