Comcast是美国最大的ISP(ISPs)或互联网服务提供商(internet service providers)之一。事实上，它拥有该国大约 85% 的市场份额。尽管有这种主导地位，但许多人对这项服务的看法并不那么讨人喜欢。
然而，康卡斯特(Comcast)实际上在很多方面改进了他们的服务，尤其是向康卡斯特(Comcast)互联网客户 提供的xFi服务。
那么什么是xFi？xFi 是 Xfinity 为客户提供的个性化 Wi-Fi 体验，可通过仪表板轻松控制您的家庭网络、密码、家长控制等。下面将解释更多细节。
Xfinity xFi 的好处(Xfinity xFi Benefits)
Xfinity 一开始就为客户提供了几项主要优势。当您注册Internet服务时，技术人员将上门为您设置调制解调器和无线网关。技术人员还将进行服务评估，以确定您家中的任何区域是否可以从增程器中受益。
这些设备称为 xFi Pod，可将您的 Wi-Fi 服务范围扩展到(extend the reach of your Wi-Fi service)整个家庭。如果信号必须穿过太多墙壁并因此被削弱，Pod(Pods)将充当中继点来加强和增强信号。它们还在每个吊舱底部有两个内置以太网端口。(Ethernet)
一个吊舱通常足以解决两居室家庭的连接问题，而两个吊舱更适合有五间卧室和较厚墙壁的家庭。虽然价格昂贵，但Xfinity有时会免费向需要它们的人发放Pod 。(Pods)
这也只是Xfinity提供的好处的开始。
内置安全性(Built-in Security)
Xfinity xFi Advanced Security是一款内置工具，可自动监控连接到家庭网络的任何设备。这意味着任何手机、平板电脑、笔记本电脑甚至游戏机都将受到监视和保护。(watched and protected.)
如果检测到任何威胁，Xfinity 会提醒您，尽管它会自动阻止它遇到的大多数危险内容。一些好处是：
- 阻止(Stops)对恶意网站的访问并防止网络钓鱼攻击
- 阻止远程访问您家中的智能设备
- 实时监控设备并在检测到异常行为时发送警报
- 自动适应您的家庭网络并更新其威胁数据库
由于包含此功能，因此无需其他软件。您只会在您的 xFi 应用程序上收到警报。
家长控制权(Parental Controls)
父母总是关心他们的孩子接触到什么样的内容(kind of content their children are exposed to)。Xfinity xFi提供易于使用的家长控制，让家长可以限制特定设备访问互联网的时间（从而限制孩子的电话时间）并自动阻止可疑网站。
这些控件允许家长阻止特定网站、关键字等，但您也可以允许访问受信任计算机上的任何网站。由于这些硬件级别的限制，孩子们无法通过手机找到解决方法。
高速(High Speeds)
Xfinity 擅长的一个领域是它提供的高速互联网服务(high-speed internet services)。虽然价格因地区而异，但计划可以分为六种不同的选择。
Performance Starter计划提供降低 25 Mbps的基本速度。Performance Select提供高达 100 Mbps的下行速度。Performance Pro Plus为用户提供高达 200 Mbps的下行速度。
如果您需要比这更快的速度，那么Blast！Pro Plus 计划提供高达 400 Mbps的下行速度，而 Extreme Pro Plus 提供高达 600 Mbps的下行速度。最快的选择是高达 1000 Mbps的(Mbps)千兆(Gigabit)计划。所有计划都有 1.2 TB 的数据上限。
如果数据上限的想法对您没有吸引力，那么您很幸运。某些地区的客户可以选择每月只需多花几美元的无限制数据计划——考虑到超出数据限制的高额费用，这非常值得。
设备自由度(Equipment Freedom)
虽然Xfinity将提供调制解调器/路由器组合单元，但您不仅限于该设备。如果您愿意，您可以自由使用自己的路由器，但缺点是您会错过一些好处——包括高级安全(Advanced Security)功能。
并非所有设备都与 Xfinity 兼容，但如果您正在寻找对您家的完全控制，或者您只想使用三频路由器，您将需要选择您自己的设备而不是提供的选项。您还可以每月节省一点租金。
访问 xFi 应用程序(Access to xFi App)
xFi 应用程序为用户提供触手可及的大量信息。它不仅显示连接到网络的每个设备的故障，还允许用户为每个设备设置单独的控件。
如果一台设备提取的数据多于应有的数据，您可以禁用它。这是确保孩子在应该睡觉时不使用互联网的好方法。如果需要，您还可以将其用作帮助您集中注意力的一种方式，在您的工作完成之前关闭您对互联网的访问。
如果您遇到连接问题，xFi 应用程序可以让您无需物理接触即可重新启动网关。该过程大约需要 12 分钟，并且可以轻松纠正大多数主要的操作错误。
Xfinity 主页(Xfinity Home)
除了xFi应用程序，Xfinity 客户还可以访问Xfinity Home。这是 Xfinity自己的智能家居平台(own smart home platform)，可以轻松访问兼容的智能家居设备。它还提供对 Xfinity 家庭安全系统的访问，这是 24/7 专业监控附带的可选费用。
如果您是 Xfinity 的客户并且想打入智能家居世界，将您的所有设备保持在同一个生态系统中可以更轻松地确保安全性并提供更好的易用性。
xFi值得吗？(Is xFi Worth It?)
在全国许多地区，Xfinity是互联网(Internet)服务的唯一选择。即使您有其他选择，Xfinity xFi也值得一试。它为您的家庭Wi-Fi(Wi-Fi)网络提供的控制级别几乎是无与伦比的，并且自动安全功能加强了您的互联网安全工作。
xFi Pod 也是一个巨大的好处。一次性购买意味着您可以在家中的任何地方建立稳定的连接，即使是在路由器对面的房间里。
Comcast（和Xfinity）改进了他们的服务产品，并在您选择转换计划时赢得了值得考虑 的ISP之一的地位。(ISPs)
What Is Xfinity xFi? Comcast’s Personal WiFi Experience Explained
Comcast is one of the nation’ѕ biggest ISPs, or internet service providers. In fact, it has somewhere around 85% of the country’s market share. Despite this dominance, many people have less-than-flattering opinions of the service.
However, Comcast has actually improved their service in a number of ways, especially the xFi service provided to Comcast internet customers.
So what is xFi? xFi is Xfinity’s personalized Wi-Fi experience for customers that provides easy control of your home network, passwords, parental controls, and more through a dashboard. More details will be explained below.
Xfinity xFi Benefits
Xfinity provides customers with several major benefits right out of the gate. When you register for Internet service, a technician will visit your home to set up your modem and wireless gateway. The technician will also perform a service evaluation to determine if any areas of your home could benefit from range extenders.
These devices, called xFi Pods, extend the reach of your Wi-Fi service throughout the home. If the signal has to pass through too many walls and is weakened as a result, the Pods act as relay points to strengthen and boost the signal. They also have two built-in Ethernet ports on the bottom of each pod.
A single pod is often enough to solve connectivity problems in two bedroom homes, while a two-Pod pack is better for homes with five bedrooms and thicker walls. While expensive, Xfinity will sometimes issue the Pods for free to those that need them.
That’s just the start of the benefits Xfinity offers, too.
Built-in Security
Xfinity xFi Advanced Security is a built-in tool that automatically monitors any device connected to your home network. This means that any phone, tablet, laptop, and even gaming console will be watched and protected.
Xfinity will alert you if any threats are detected, although it automatically blocks most dangerous content it encounters. A few of the benefits are:
- Stops visits to malicious websites and protects against phishing attacks
- Blocks remote access to your home’s smart devices
- Monitors devices in real-time and sends alerts when strange behavior is detected
- Automatically adapts to your home network and updates its threat database
Since this feature is included, no additional software is required. You will simply receive the alert on your xFi app.
Parental Controls
Parents are always concerned about the kind of content their children are exposed to. Xfinity xFi provides easy-to-use parental controls that let parents limit the amount of time specific devices can access the internet (thus limiting children’s phone time) and automatically blocking suspicious websites.
The controls allow parents to block specific websites, keywords, and more, but you can also allow access to any website on a trusted computer. Thanks to these hardware-level restrictions, children cannot find workarounds through their phones.
High Speeds
One area where Xfinity excels is in the high-speed internet services it offers. While the prices will vary from region to region, plans can be broken down into six different options.
The Performance Starter plan provides basic speeds with 25 Mbps down. Performance Select provides up to 100 Mbps down. Performance Pro Plus gives users up to 200 Mbps down.
If you need faster speeds than this, then the Blast! Pro Plus plan provides up to 400 Mbps down, while the Extreme Pro Plus gives up to 600 Mbps down. The fastest option is the Gigabit plan with up to 1000 Mbps down. All plans have a 1.2 TB data cap.
If the idea of a data cap doesn’t appeal to you, you’re in luck. Customers in certain areas can opt for an unlimited data plan for just a few more dollars per month–well worth it, given the high fees for exceeding your data limits.
Equipment Freedom
While Xfinity will provide a modem/router combo unit, you aren’t limited to only that device. You are free to use your own router if you like, but the downside is that you miss out on a few benefits–the Advanced Security feature included.
Not all equipment is compatible with Xfinity, but if you’re looking for total control of your home or you just want to use a tri-band router, you will want to opt for your own equipment over the provided options. You’ll also save a bit each month in rental fees.
Access to xFi App
The xFi app provides users with a massive amount of information at their fingertips. Not only does it show a breakdown of every device connected to the network, but it allows users to set individual controls for each of these devices.
If one device is pulling more data than it should, you can disable it. This is a great way to ensure children are not using the internet when they should be asleep. You can also use it as a way to help you focus if needed, shutting off your access to the internet until your work is complete.
If you run into connection issues, the xFi app makes it possible to restart your gateway without physically touching it. The process takes about 12 minutes and corrects most major operational errors with ease.
Xfinity Home
In addition to the xFi app, Xfinity customers can access Xfinity Home. This is Xfinity’s own smart home platform, allowing easy access to compatible smart home devices. It also provides access to Xfinity’s home security system, an optional expense that comes with 24/7 professional monitoring.
If you are an Xfinity customer and you want to break into the smart home world, keeping all of your equipment within the same ecosystem makes it easier to ensure security and provides better ease of use.
Is xFi Worth It?
In many areas throughout the country, Xfinity is the only option for Internet service. Even if you have other options, Xfinity xFi is worth checking out. The level of control it grants over your home Wi-Fi network is nearly unmatched, and the automatic security features strengthen your internet security efforts.
The xFi Pods are also a huge benefit. The one-time purchase means you can have a steady connection anywhere within your home, even in rooms on the opposite side of the house from the router.
Comcast (and Xfinity) have improved their service offerings and earned a place as one of the ISPs worth considering when you choose to switch plans.
