Usually, but you may need to contact your cable company to give you instructions on how to access the internal router functions.
If your internet service provider is AT&T, and you have one of their modem-router combination devices, you may have problems unless you are using a separate router. AT&T started rolling out firmware upgrades that disable customer access to configuration settings. It is hard to understand why they do this unless they want to ensure they can collect data on every site you visit.
In situations like this, you might want to consider our CYBERsitter BLACK - with router package. We will provide a top quality gigabit dual band WiFi router completely preconfigured and tested so all you need to do is plug it in. It is guaranteed to work with EVERY internet provider.
