Have you already subscribed to Comcast XFinity’s cable internet plans and you are looking for a compatible cable modem for your home network? Let us take a look at the structure and features of the ARRIS T25 cable modem that was designed for XFinity cable internet and voice service users.

When trying to find the best cable modem for my home network, my greatest satisfaction was based on finding one that was reliable, efficient and one that was durable and user-friendly at the same time. Preferably, I needed one that would work with my already existing Internet Service Provider. For these reasons, I found myself purchasing the ARRIS T25 cable modem which is compatible with Comcast XFinity cable internet that I had already subscribed to. Aside from that, I am benefiting from the fact that I have stopped paying my internet service provider a separate modem rental fee.

Design and Structure

It is an average sized router that fits into almost all spaces in your home with its size dimensions at 11.1 x 7.5 x 2.8 inches and weighs 2.16 which makes it portable during deployment.

When the LED indicator on the power part is solid white it shows that your cable modem is powered on and is ready for use. The US/DS LED indicator blinks when it is scanning for upstream and receiving data and it is solid white when the upstream and downstream channels are connected. Aside from that, the LED indicator on both telephone lines blink when the telephone line is off-hook or when you have a call in progress and it remains solid white when the telephone service on the lines are connected and activated. As for the cable modem status, the LED indicator remains solid white when it is connected to the internet and it blink when it is scanning for an internet connection.
