Yup, and you will get "up to" 400, (or 200, or 100, or 50) providing no one in your neighborhood who is connected to Optimum, happens to be online at the time — like maybe at 3am. Otherwise regardless of the "up to" speed they say you have, your service slows to a crawl — that is when, of course, the service isn't lost completely several times a day for 5-10 minutes at a time plus the time your modem takes to resync.
