Comcast Xfinity Approved Modems (2020 List)

Spending money that you don’t need to is a pastime for some, but it shouldn’t be for you, especially when it comes to your Comcast approved modem. 

While Comcast advertises that their $10 a month rental fee ($120/year) is a good deal, in reality they are taking your hard-earned cash under the guise of doing you a favour.

Instead of using the generic modem that you can rent from Comcast, you should buy your own Xfinity compatible modem. Not only is it cheaper, but you will get more of the power that you really needed from your internet.

Eliminate Rental Fees

No one wants to throw away money when they don’t need to, so you don’t need to waste $10 a month on rental fees. Keep your money and put it to better use. If you think about it, $10 a month adds up to $120 a year.

Even after that, you still don’t own the modem and you could have put that money toward a modem you can keep forever.

Faster Internet Speed

In the modern world, we need all of the speeds that we can get, which you will never be able to get from a rental modem. Instead of suffering through the sluggish speeds of a rental modem, you would be better off buying your own Comcast approved modem. 

Better Coverage

Renting a modem also means that you are not as likely to get a quality router built into your modem. As a result, you might not have the right level of coverage that you really need through your entire network.
