I want to say your ability to stream well depends on your internet speed from your provider and the number of devices that will be connected. 50 mbps and above should work well, also get a good router. You will enjoy the modem, it delivers.
Sorry, there was a problem. Please try again later.They could, assuming that the system you are comparing to was limited by the modem. The data path from the source of data to your screen is a long line of devices connected serially, so the net throughput is limited by the slowest element in that chain. If the slowest element in the chain is your modem, then getting a faster modem helps. I think that was in fact the case in my home network. I didn't see any impact on movies though, since it was fast enough for movies to start with, but I did see some improvement in other things. So, if your internet provider, for instance, is just not sending the data fast enough to start with (limiting your bandwidth to a low value), then no amount of improvement in your modem speed will help. If you are getting the streaming data via wifi (rather than an ethernet cable), that would degrade transmission speed too. WIFI has lower effective speed than a wire (transmission specs notwithstanding). So if you are watching on a tablet or a laptop connected to the internet via wifi, that might be the case. wifi is also subject to radio interference which can degrade performance. Also if you have a lot of neighbors using wifi and you and they are all on the same wifi channel, that would degrade performance. (People rarely change the default channel setting when they set up their wifi router, so often many local networks are competing for access to the same channel. That causes lots of packet collisions which can decrease throughput.) The internet protocol (IP) for transmitting data is VERY fault tolerant. It's very good at detecting when a packet fails and automatically re-transmitting it, a zillion times if necessary, without giving any sign of a problem. So a lot of different types of problems just show up as a decrease in speed. I didn't replace my modem to get faster throughput. I replaced it because the old one broke AND I already new that the bandwidth Comcast was giving me was a bit higher than the old modem could handle. So when it was time for a new modem, I bought a faster one. It couldn't hurt.
