不少人家里都有Wi-Fi時(shí)好時(shí)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(guān)鍵時(shí)刻網(wǎng)絡(luò)出問題,，會(huì)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(kuò)展Wi-Fi范圍,，改善無線網(wǎng)絡(luò)環(huán)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(shè)個(gè)復(fù)雜點(diǎn)的密碼以防網(wǎng)絡(luò)被盜用。）

以下是可以選用的幾款產(chǎn)品,。

eero

改善家庭Wi-Fi有兩種方法,，一是使用Wi-Fi擴(kuò)展器，二是啟用網(wǎng)狀網(wǎng)絡(luò),。其中網(wǎng)狀網(wǎng)絡(luò)是更新潮的方法,，在房間里安裝多個(gè)網(wǎng)絡(luò)節(jié)點(diǎn)（每個(gè)無線節(jié)點(diǎn)設(shè)備大小跟蘋果電視Apple TV差不多）讓無線網(wǎng)絡(luò)覆蓋家中各處，處理高流量的需求,。（如果家里有個(gè)孩子玩線上視頻游戲,，另一個(gè)在Netflix看視頻，你要查看電郵,，你的伴侶要瀏覽社交網(wǎng)站Facebook,，網(wǎng)狀網(wǎng)絡(luò)就能發(fā)揮作用。）

eero是市面上最出色的一款網(wǎng)狀網(wǎng)絡(luò)設(shè)備,，售價(jià)在299美元到398美元,，具體看需要多少個(gè)eero單元數(shù)量。設(shè)備安裝簡(jiǎn)便，雖然不能像某些高端路由器一樣網(wǎng)速驚人,，但能保證無線網(wǎng)絡(luò)穩(wěn)定覆蓋家里每個(gè)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(lián)網(wǎng)的設(shè)備,，控制部分系統(tǒng)設(shè)置,。

Linksys 網(wǎng)絡(luò)系統(tǒng)Velop

和eero一樣，這款能建立網(wǎng)狀網(wǎng)絡(luò)拓展家庭Wi-Fi的設(shè)備也不便宜（預(yù)計(jì)費(fèi)用約為500美元）,，卻能提供無死角的無線網(wǎng)絡(luò),。同其他一些網(wǎng)狀網(wǎng)絡(luò)系統(tǒng)相比，Velop網(wǎng)絡(luò)設(shè)備有點(diǎn)大,，每個(gè)裝置高度都超過7英寸（合17.78厘米）,。據(jù)稱兩個(gè)裝置的無線覆蓋范圍就可達(dá)到4000平方英尺（約合372平方米），再增加一個(gè)發(fā)射裝置就能覆蓋4500平方英尺（約合418平方米）,。Velop安裝簡(jiǎn)易,，適合對(duì)網(wǎng)絡(luò)技術(shù)一竅不通的新手。

Netgear AC1200臺(tái)式Wi-Fi擴(kuò)展器

無線網(wǎng)絡(luò)擴(kuò)展器通常比網(wǎng)狀網(wǎng)絡(luò)便宜,，但通常無法負(fù)載高流量,，美國網(wǎng)件公司Netgear售價(jià)83美元的產(chǎn)品AC1200就是如此。該產(chǎn)品有助于清除網(wǎng)絡(luò)死角,，但可能更適合單身人士或者小兩口,，對(duì)聯(lián)網(wǎng)要求高的大家庭不那么適用。

Netgea的AC1200易于安裝,，無線覆蓋穩(wěn)定,。設(shè)備上有一個(gè)USB 3.0接口和五個(gè)以太網(wǎng)端口，可以連接Apple TV等設(shè)備,，即使不支持Wi-Fi的設(shè)備也可以聯(lián)網(wǎng),。最重要的是，設(shè)備上可以精確調(diào)節(jié)5 GHz頻段在內(nèi)的現(xiàn)有Wi-Fi網(wǎng)速,，自由決定擴(kuò)展哪個(gè)頻段的無線網(wǎng)絡(luò),。這意味著，無論你用的網(wǎng)絡(luò)是普通電纜還是光纖,，都可以最大限度利用好網(wǎng)速,。

TP-Link AC1900臺(tái)式雙頻段Wi-Fi擴(kuò)展器

這款售價(jià)109美元的Wi-Fi擴(kuò)展器有不少優(yōu)點(diǎn)，也確實(shí)能延長路由器信號(hào)傳輸距離,，和Netgear的AC1200一樣,，設(shè)備上也有五個(gè)以太網(wǎng)接口，供視頻游戲機(jī)等設(shè)備連接,。但也有一些缺陷,，比如沒有家長控制設(shè)置,，也沒有USB接口。不過安裝運(yùn)行簡(jiǎn)便,。如果你只希望消除Wi-Fi死角,，這款設(shè)備會(huì)令你滿意。（財(cái)富中文網(wǎng)）

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.
