Welcome to the forum. I've run a few checks on your connection and everything looks great. What speed test results are you getting using a wired connection to a PC on a site like speedtest.net which SonarUK suggested? Also is your Xbox connected wired or wireless? There are a lot of factors that can affect wireless so for more stability when playing online I'd recommend using an ethernet connection.
