My small city has become pretty competitive for internet and TV service. Yesterday my Cable One account, which has now become Sparklight, offered me a 1000Mbps down unlimited data , with 50Mbps up for 75 bucks a month and I jumped at it in as much as I was paying 65 bucks a month for 200Mbps down with 700GB cap and 10Mbps up. Once they made the upgrade I started speed testing. Before the upgrade I always test 190Mbps to 230Mbps down and 10Mbps up which is what I was paying for. However, since the upgrade I always get 50Mbps upload test results but the fastest I have gotten on download is 382Mbps and most of the tests result are 175 to 250Mbps. I have tested this result directly off my Ubiquity Edge gigabit Router and even directly off my six month old Motorola 24x8 Cable Modem, Model MB7621, DOCSIS 3.0. Both of these will handle 1000Mbps. I have tested on multiple PCs with Intel gigabit Nics.
So is this low download speed a failure of Sparklight to provide 1000Mbps or because of a limitation of my NIC ? In essence the network can now deliver 300 down to multiple PCs simultaneously but an individual NIC cannot achieve 1000Mbps down... is that what is going on?
