消灭Wi-Fi死角 这些设备包你在家安心上网

不少人家里都有Wi-Fi时好时坏的房间。如果在上传一份重要的文件或者在Netflix看片看到关键时刻网络出问题，会让人很郁闷。

房子越大，越有可能存在Wi-Fi死角。但这不代表只能接受。有很多工具可以扩展Wi-Fi范围，改善无线网络环境。（只是别忘了，那样一来，你的邻居或者街上的陌生人或许也能连上你家Wi-Fi，所以要设个复杂点的密码以防网络被盗用。）

以下是可以选用的几款产品。

eero

改善家庭Wi-Fi有两种方法，一是使用Wi-Fi扩展器，二是启用网状网络。其中网状网络是更新潮的方法，在房间里安装多个网络节点（每个无线节点设备大小跟苹果电视Apple TV差不多）让无线网络覆盖家中各处，处理高流量的需求。（如果家里有个孩子玩线上视频游戏，另一个在Netflix看视频，你要查看电邮，你的伴侣要浏览社交网站Facebook，网状网络就能发挥作用。）

eero是市面上最出色的一款网状网络设备，售价在299美元到398美元，具体看需要多少个eero单元数量。设备安装简便，虽然不能像某些高端路由器一样网速惊人，但能保证无线网络稳定覆盖家里每个角落。要是买了亚马逊的人工智能音箱Echo，还可以用来寻找联网的设备，控制部分系统设置。

Linksys 网络系统Velop

和eero一样，这款能建立网状网络拓展家庭Wi-Fi的设备也不便宜（预计费用约为500美元），却能提供无死角的无线网络。同其他一些网状网络系统相比，Velop网络设备有点大，每个装置高度都超过7英寸（合17.78厘米）。据称两个装置的无线覆盖范围就可达到4000平方英尺（约合372平方米），再增加一个发射装置就能覆盖4500平方英尺（约合418平方米）。Velop安装简易，适合对网络技术一窍不通的新手。

Netgear AC1200台式Wi-Fi扩展器

无线网络扩展器通常比网状网络便宜，但通常无法负载高流量，美国网件公司Netgear售价83美元的产品AC1200就是如此。该产品有助于清除网络死角，但可能更适合单身人士或者小两口，对联网要求高的大家庭不那么适用。

Netgea的AC1200易于安装，无线覆盖稳定。设备上有一个USB 3.0接口和五个以太网端口，可以连接Apple TV等设备，即使不支持Wi-Fi的设备也可以联网。最重要的是，设备上可以精确调节5 GHz频段在内的现有Wi-Fi网速，自由决定扩展哪个频段的无线网络。这意味着，无论你用的网络是普通电缆还是光纤，都可以最大限度利用好网速。

TP-Link AC1900台式双频段Wi-Fi扩展器

这款售价109美元的Wi-Fi扩展器有不少优点，也确实能延长路由器信号传输距离，和Netgear的AC1200一样，设备上也有五个以太网接口，供视频游戏机等设备连接。但也有一些缺陷，比如没有家长控制设置，也没有USB接口。不过安装运行简便。如果你只希望消除Wi-Fi死角，这款设备会令你满意。（财富中文网）

Many homes have rooms where the Wi-Fi is great one moment, and then vanishes the next. If you're uploading a critical file or at a crucial moment during a Netflix binge, the spottiness can be frustrating.

The bigger your home, the more likely you'll have an Internet black hole. But you don't have to accept it. There are plenty of tools that can help you extend and improve the range of your home's Wi-Fi. (Just remember that neighbors or strangers on the street may be able to access your Wi-Fi as well, so be sure to use a strong password to keep them out.)

Here are a few products to consider.

eero

There are two ways to improve your home's Wi-Fi—with an extender or via a mesh network. The later is a newer option and uses multiple hubs (each roughly the size of an Apple TV device) to blanket the home in wireless connectivity and handle high volume traffic demands. (A good thing to have if you've got one kid playing an online video game and another watching Netflix while you check email and your spouse browses Facebook).

Eero, which costs $299 to $398 depending on the number of units you choose, is one of the best mesh devices around. It's simple to set up, and while it doesn't provide the blazing speeds of some high-end routers, it does ensure that all corners of your home have strong coverage. And if you've got Amazon's Echo, you can use it to find connected devices and control some of the system's settings.

Linksys Velop

Like eero, this mesh network isn't the cheapest option to extend your home Wi-Fi (expect to pay about $500), but it provides seemless coverage using a single network. The hubs are a bit more obtrusive than some mesh systems, with each standing over 7 inches tall. Two units can reportedly cover up to 4,000 square feet, while a third extends that to 4,500 square feet. Set-up is easy, making this a good option for people with little tech know-how.

Netgear AC1200 Desktop Wi-Fi Range Extender

Range extenders, like this $83 one from Netgear, tend to be less expensive than mesh networks, but they often can't handle heavy traffic loads. They help get rid of dead spots, but they may be better suited for individuals or couples than large, connected families.

Netgear's AC1200 is easy to set up and has an excellent coverage area. It has five Ethernet ports that you can plug devices like Apple TVs into, if they don't support Wi-Fi, as well as a USB 3.0 connection. Best of all, it will determine the speed of your existing Wi-Fi (including 5 GHz bands) and ask which of the bands you'd like to extend, meaning you'll get the most out of your cable or fiber modem.

TP-Link AC1900 Desktop Dual Band Wi-Fi Range Extender

There's plenty to like about this $109 Wi-Fi extender. It does a good job of stretching the signal from your router and, like Netgear, comes with five wired Ethernet ports for things like video game consoles. But it falls a bit short in areas like parental control (there are none) and lacks a USB port. It's easy to get up and running, though. And if you're simply looking to eliminate dead zones, it will get the job done admirably.
