You don’t buy a new XFINITY modem first of all. They are selling one to rent out from them for a monthly fee (usually around 10) $once you register for their service. Your own modem can, however, offer a number of benefits:

Save Money:

If you lease a modem, the lack of money in the short term would definitely lead you to save money, because you do not pay a monthly payment for the service.

When you get an $80 modem, which saves $10 a month, you’ll have saved money by the end of your first year! And before I claim that at the completion of your contract, you will hold your modem.

Get A Better Modem:

If you can pick your own modem, you can select the best modem for yourself. Whereas people with sometimes trouble renting their modems are recorded, you can end these problems when you buy your own.

Separate Modem:

Firstly, you need to make sure that your modem is compatible with Comcast, whether you choose to buy cable modems/routers or a separate modem and router (not the router, every router will operate with all modems-it’s OK!).

You can check directly with Comcast or if you don’t want to, the service is compatible with all the modems in our following list.

Advantages of a Separate Modem:

Top Quality Router:

While a combo of routers is often decent enough, you probably have to buy a separate router if you want a top-of-the-range router with all the latest features.

It means the latest features of your router include the current WIFI specifications, QoS settings, triple channel, etc.

To buy a different router and modem can be the way to use the highest quality network router.

Able to upgrade each part:

In the same way, if you do not now want to purchase a top range of the router, but believe it can be in the future, you can purchase a separate modem and router.

Alternatively, you will either be left with the cable/router or have to purchase both items again, whether you choose the mixed option.

Nonetheless, that is not to suggest that a cable modem / router combination does not give any value! There are still advantages to a combo product if you are not worried about having the best possible router.

Guidelines for Installing XFINITY Modem:

Make sure that your modem is XFINITY compliant.

Enter your old modem. Remove your old modem.

Connect your new modem to the internet cable. If you do not know which socket to insert, consult the instructions manual of your modem. There is, however, only one cable available for port fit, so it should be quite clear!

Attach the modem to the power socket and trigger the modem. You’re good to start to install your router if you come on the lights.

You can now configure your router with your modem installed.
