Hey, my ISP recently increased the connection speed from 8mbps to 24mbps. However, speedtest.net and other testing sites only indicate that it has increased to only about 10mbps. My router is a ZyXel P-660HW-D1, and it IS quite old. And as I'm not very experienced when it comes to routers and their specifications, I'm not sure if it's just the router not supporting more than 10mbps. Could it be a router issue?
