Can Xfinity see which devices are using data?

Yes, it can see the devices that are using the Xfinity setup. This is a feature that was introduced in 2017 on the xFi app, which allows users to see the usage data of different devices, as well as other features such as setting up Wi-Fi connections, setting parental controls, and assigning devices to different users.

Instead of paying high amounts every month and struggling to find the devices using your data, there are methods you can use to track your usage per month. The most straightforward solution is through using the xFi app. This is particularly important if you want to stay within the 1TB monthly caps, which Comcast imposes on Xfinity users.

Why Xfinity imposes data caps

Xfinity, along with other ISPs, impose data caps as a way to regulate their broadband traffic and reduce the data amounts you can download when using their internet connections. Most of their competitors also have caps, with others placing higher limits and others allowing unlimited data usage in some packages, as the table below shows:

ISP	Data cap	Charges for surpassing the cap
Xfinity	1TB to Unlimited	$10 for every 50GB surpassed
Frontier	Unlimited	None
AT&T	1,024GB to Unlimited	$10 for every 50GB surpassed
Cox	1,024GB to Unlimited	$10 for every 50GB surpassed
Mediacom	150GB to 6,144GB	$10 for every 50GB surpassed
CenturyLink	1,024GB to Unlimited	None
Google Fiber	Unlimited	None
Spectrum	Unlimited	None
RCN	Unlimited	None
Verizon Fios	Unlimited	None

If your aim is getting a solid internet connection for a small household or yourself, the 1TB data cap Xfinity offers is fine and you will barely surpass it. However, if you are living with people that use data heavily such as 4K video streamers and gamers, you will want to check out their unlimited data plans to avoid paying high fees when you surpass the monthly limit.

How you can tell your Xfinity data usage

Through the Xfinity portal

On Comcast’s website, you can opt to log in to your account and check the data usage for the month. If you do not have a Comcast account, you can make one by clicking on the ‘Create One’ button and use your Comcast account details such as the social security number, mobile phone number, and Comcast account number. If you do not remember your password, simply change it by clicking on the ‘Forgot username or password?’ link at the bottom of the login page.

After logging in, check the tabs on the top of the homepage and click on ‘Devices’. This will bring up a Usage Overview option under its menu, so click on this and select ‘View Data Usage’.

This will take you to the ‘My Data Usage’ page. You can also choose to access it again in future directly from the page link, or bookmark the page.

This method will show you the data you are using on average on a monthly basis, which will help you if you want to estimate whether or not you will hit your 1 TB data caps according to your usage. An instance would be the page showing you that you have used 500 GB in the first week of the month, so this will tell you that you need to slow down your usage to avoid hitting the cap before the month ends.

Using your smartphone

This will involve downloading the Xfinity My Account app, which you can access on both the Android play store and iPhone App Store. In many ways, it is more convenient compared to the website method we discussed previously, as you can access your usage data on the go.

Download the app and sign in to your account using your Comcast details.

Once you log in, check the bottom section of the app and click on the ‘Internet’ icon to see your home internet connection status, as well as data usage.

Similar to the website method, you can find out about your data usage in previous months by clicking on the section ‘Your total data usage is’. This will show you all your data use in summary over previous months, although this may not be in detail as much as the website portal format.

What happens when you hit the Xfinity data usage cap?

The good news is that you will not be penalized immediately for any surpassing of data caps, as Comcast’s policy allows users to get a two-month courtesy period before you begin getting charges for exceeding the cap.

After the two-month period is over, Comcast will immediately charge you $10 for every 50GB you exceed, with the maximum charge going up to $200 monthly. On the other hand, you can opt to buy unlimited data, which costs $50 monthly, if you see that your data consumption trends are higher than what a limited cap plan can provide.

Tips to reducing your Xfinity data usage

Protect your network against bots – you may be receiving spam or malicious software on your computer or smartphone, which is consuming your data without your knowledge. To prevent this and secure your network, Xfinity offers their users a Bot Detection and Removal Tool.

Securing your network – In line with the first tip, you can take additional measures to protect your wireless network from other threats, particularly through the Xfinity admin tools.

Application settings – you can control the data you use through many internet-based applications, as well as disabling unused third-party services and exiting streaming services after using them such as Netflix.

Conclusion

Xfinity imposes data caps on their users, but there are measures you can use to monitor and reduce your data usage, especially if you notice that you are a heavy data consumer.
