No,it's a Netgear dsl wireless router.
Most fairly new netgear routers have that feature.If you have a router that supports dd-wrt it has a great b/width monitor.I read a lot when I was an ATT customer,over at dsl reports and other sites,I would say 90% of the posters had used less b/width than ATT was claiming they had.Just one more reason I don't trust them.You have to wonder just how accurate ATT's info is when they say (in our area) we can't effectively monitor your b/width usage.
Here is their online usage link.
