不少人家里都有Wi-Fi時好時壞的房間。如果在上傳一份重要的文件或者在Netflix看片看到關鍵時刻網絡出問題，會讓人很郁悶。

房子越大，越有可能存在Wi-Fi死角。但這不代表只能接受。有很多工具可以擴展Wi-Fi范圍，改善無線網絡環境。（只是別忘了，那樣一來，你的鄰居或者街上的陌生人或許也能連上你家Wi-Fi，所以要設個復雜點的密碼以防網絡被盜用。）

以下是可以選用的幾款產品。

eero

改善家庭Wi-Fi有兩種方法，一是使用Wi-Fi擴展器，二是啟用網狀網絡。其中網狀網絡是更新潮的方法，在房間里安裝多個網絡節點（每個無線節點設備大小跟蘋果電視Apple TV差不多）讓無線網絡覆蓋家中各處，處理高流量的需求。（如果家里有個孩子玩線上視頻游戲，另一個在Netflix看視頻，你要查看電郵，你的伴侶要瀏覽社交網站Facebook，網狀網絡就能發揮作用。）

eero是市面上最出色的一款網狀網絡設備，售價在299美元到398美元，具體看需要多少個eero單元數量。設備安裝簡便，雖然不能像某些高端路由器一樣網速驚人，但能保證無線網絡穩定覆蓋家里每個角落。要是買了亞馬遜的人工智能音箱Echo，還可以用來尋找聯網的設備，控制部分系統設置。

Linksys 網絡系統Velop

和eero一樣，這款能建立網狀網絡拓展家庭Wi-Fi的設備也不便宜（預計費用約為500美元），卻能提供無死角的無線網絡。同其他一些網狀網絡系統相比，Velop網絡設備有點大，每個裝置高度都超過7英寸（合17.78厘米）。據稱兩個裝置的無線覆蓋范圍就可達到4000平方英尺（約合372平方米），再增加一個發射裝置就能覆蓋4500平方英尺（約合418平方米）。Velop安裝簡易，適合對網絡技術一竅不通的新手。

Netgear AC1200臺式Wi-Fi擴展器

無線網絡擴展器通常比網狀網絡便宜，但通常無法負載高流量，美國網件公司Netgear售價83美元的產品AC1200就是如此。該產品有助于清除網絡死角，但可能更適合單身人士或者小兩口，對聯網要求高的大家庭不那么適用。

Netgea的AC1200易于安裝，無線覆蓋穩定。設備上有一個USB 3.0接口和五個以太網端口，可以連接Apple TV等設備，即使不支持Wi-Fi的設備也可以聯網。最重要的是，設備上可以精確調節5 GHz頻段在內的現有Wi-Fi網速，自由決定擴展哪個頻段的無線網絡。這意味著，無論你用的網絡是普通電纜還是光纖，都可以最大限度利用好網速。

TP-Link AC1900臺式雙頻段Wi-Fi擴展器

這款售價109美元的Wi-Fi擴展器有不少優點，也確實能延長路由器信號傳輸距離，和Netgear的AC1200一樣，設備上也有五個以太網接口，供視頻游戲機等設備連接。但也有一些缺陷，比如沒有家長控制設置，也沒有USB接口。不過安裝運行簡便。如果你只希望消除Wi-Fi死角，這款設備會令你滿意。（財富中文網）

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.
