We have new Metronet service at 500 mbps. Anytime I do a speed test on the app it comes in at just above that number. But if I run a speed test on my laptop from another source, say gospeedcheck.com, it never gets near that number, usually in the 250 - 350 mbps range. I am just try to be sure that I am getting what I am paying for. Can you help me?
