Sitecom introduces a series of standard routers but with a twist. They tagged their mainstream range from X1, X2, X3 and a more enthusiast range from X4, X5 and X6. They are all Gigabit models, but obviously the higher the number the better the feature set. all models now come with cloud security, and that's the new feature we'll discuss later on. We test the X4 WLR-4000 model.
