Does the Data Usage Meter just measure data on my PC or do I need to download multiple meters if I use multiple devices?
You don’t have to download anything to view the Data Usage Meter. It measures all data flowing through your cable modem. Each account has only one modem associated with it. If you use a single cable modem to connect multiple computers and other devices behind your modem, such as on a home network, the meter will report the combined data usage for all of those computers and devices. If you have more than one modem (and therefore more than one account) in your home, the data from each modem will be tracked by its own separate Data Usage Meter.
