How We Tested And Picked Up The Xfinity Modem?
We evaluate router speed and performance by setting up office routers and connecting them to a local test server. The next step is transmitting test data from our wireless devices to the server. Measurements are taken in consistent, frequent intervals, which help us accurately determine fluctuations in wifi speeds.
The first tests include testing the wifi speeds without any obstacles between the router and the wireless device, so the connection is naturally as strong as ever.
We also changed the distance between the router and the device, to 10, 20, and 30 feet, and introduced a new obstacle: a glass door blocking the view of the router.
The next few tests occur outside, keeping the router at a distance of 40, 50 feet, and with the glass door and an exterior door acting as the obstacles.
Tests are also run in a hallway which is to the left of the TV room and office, and the obstacles include an air handler unit, a glass door, and 3 walls.
To the right of the TV room and office lies the dining room, which is also a place where tests are conducted, and the obstacles, in this case, are two walls and a glass door.
We also conduct tests to determine the efficiency of video streaming: we do this by connecting a fast storage device to the router, and by streaming 4k videos to six wireless devices that are connected to the same wireless band.
Another important factor was compatibility with Comcast Xfinity. We made sure that every router we checked was compatible with Xfinity’s plans.
Things To Consider Before Buying A Modem For Xfinity
Here are a few things that should be kept in mind when looking for a new modem for Xfinity:
- The modem that you choose should be Comcast compatible, that is, it should be included in the list of their approved/supported modems.
- The modem should be compatible with your current internet plan. It should be capable of handling current internet speeds. The modem you choose should handle speeds up to at least 600/700 Mbps if you are subscribed to a plan that offers speeds and connectivity up to 400 mbps, for example.
- Gigabit plans require DOCSIS 3.1 technology and 32 x 8 channel bonding for optimal performance.
- A standalone modem and a mesh wifi system setup are ideal for large houses as it ensures consistent and fast connectivity throughout vast spaces.
- Regarding costs and benefits, standalone modems and routers might be more expensive but perform better than modem router combos.
- Monthly rental costs charged by ISPs can be eliminated by purchasing one’s own basic modem and router or a modem router combo that is compatible with your current internet plan.
- Lastly, it is important to know your exact requirements before purchasing the right product.
