導讀：Wi-Fi 協議發布至今已經第6代了。
是不是看 YouTube，刷劇一直遇到緩衝卡頓？是不是打遊戲老是被隊友罵「拖後腿」，延遲高，老是斷線？是不是家中總有幾個地方是盲區，上個廁所都沒辦法好好刷手機？是的，你可以考慮升級家裡的Wi-Fi無線網路了，選擇一款優秀的無線路由器，提升全家人的網路體驗。
基本知識Wi-Fi協議
圖片來源網路Wi-Fi 協議發布至今已經第6代了。在第六代，也就是Wi-Fi 6發布前，之前的網路協議都是以802.11n，802.11ac等來命名，另很多普通消費者不知所云，Wi-Fi 6發布會，統一將之前名字以數字來命名。現在主流的無線路由器一般都是Wi-Fi 5（AC協議），或者最新Wi-Fi 6（AX協議）
(Wi-Fi 6)
| 協議 （名字） | 頻道 | 發布 | 理論速度 | 真實速度 |
|---|---|---|---|---|
| 5Ghz | 1999 | 6-54 Mbps | 3-32 Mbps | |
| 2.4Ghz | 1999 | 11 Mbps | 2-3 Mbps | |
| 2.4Ghz | 2003 | 54 Mbps | 10-29 Mbps | |
| 2.4Ghz 5Ghz | 2009 | 2.4Ghz: 300 Mbps 5Ghz: 900 Mbps | 2.4Ghz: 150 Mbps 5Ghz: 450 Mbps | |
| 5Ghz | 2013 | 433 Mbps-1.7 Gbps | 210 Mbps-1 Gbps | |
| 2.4Ghz 5Ghz | 2018 | 9.6 Gbps | 2 Gbps |
主流無線路由器提供兩個工作頻段，2.4GHz和5GHz，很多人會把5GHz 稱為5G Wi-Fi，但是這種稱呼容易和移動設備的5G網路（5th Generation mobile networks，第五代移動網路）搞混。2.4GHz和5GHz有各自的優缺點。
2.4 Ghz 優點
2.4 Ghz 缺點
- 傳輸範圍廣
- 容易穿透障礙物
5 Ghz 優點
5 Ghz 缺點
- 傳輸速度快
- 不易受干擾
2.4Ghz 只有3個通道，而 5GHz 提供了22個通道，所以 5GHz 的傳輸速度更快，並且像微波爐、大多數的藍牙設備（耳機、鍵盤、滑鼠等）、無繩電話等都使用的是 2.4GHz 的無線頻段，會產生相互干擾。Wi-Fi也是一種電磁波。無線電波的特點是頻率越低、波長越長，傳播中損失越小、傳播覆蓋範圍就越廣，容易繞過障礙物（家中的牆壁）。反之，頻率越高，傳播範圍就越小，「穿牆」就差。所以頻率高、波長短的5GHz 信號，覆蓋範圍，穿過障礙物能力比不上2.4GHz。
附加功能- USB 3.0：允許用戶接入移動硬碟，成為簡易NAS，作為個人雲盤，方便用戶隨時隨地訪問硬碟中文件。
- USB 2.0: 有些無線路由器支持連接舊款，無法連接網路的印表機，方便從接入這個網路下的設備，無線列印文件。
- Alexa：用戶可以使用 Amazon Echo 操作無線路由器。
- IFTTT功能：If this、then that網路服務，允許用戶設定觸發條件，比如定時開關閉無線網路等。
- VPN Client/Server：通過在「VPN伺服器」下設置的賬號，用戶可以在外面，也能通過此賬號，連接回家中的網路；「VPN Client」，適用於那些家中無法單獨設置VPN的設備，在無線路由器上面統一設置，連接入此無線網路的設備會通過VPN接入指定網路。
- QoS：Quality of Service，自動分配每個設備所需的帶寬，盡量滿足同一時間，同一個網路下，各種網路服務的使用。
- Time Machine 時間機器：連接在此無線路由器下面的 MacBook，通過此功能，將 macOS備份到連接在此無線路由器下的移動硬碟中。
區別於本文之後會介紹的 Mesh 無線路由器，目前市場上大部分是傳統的無線路由器，造型各異，有像很多天線的，有些是內置天線的，價位高低不等。我們會將 Wi-Fi 5 和 Wi-Fi 6 的無線路由器，分品牌介紹。固件、功能，同一個品牌之間沒有太大區別，分開只是方便查詢。
Wi-Fi 5現在完全支持 Wi-Fi 6的設備還不是很多，並且 Wi-Fi 6 的無線路由器價格比 Wi-Fi 5的貴上一檔，花相同的錢，可以買到中高端的 Wi-Fi 5 路由器，但如果選擇 Wi-Fi 6，可能只能選入門款了。很多科技網站做個測試，其實很多時候，Wi-Fi 6 的速度和 Wi-Fi 5路由器差不多。不過當支持 Wi-Fi 6 的設備普及后，選擇 Wi-Fi 6 的路由器可以獲得更穩定的網路傳輸。
ASUS 華碩華碩的無線路由器憑藉其優秀的硬體和其背後出色的固件，長期霸佔銷售榜前幾名。其使用的 ASUSWRT 固件，UI 漂亮、功能多，再不行，高階玩家還可以刷基於 ASUSWRT 二次開發的 Merlin 梅林固件，國內還有大神開發了更適合國內網路環境的固件，「解鎖」更多功能，裝個飛機場、X雷離線下載、全局屏蔽廣告等等。
除了普通華碩的路由器，旗下專業電競品牌 「信仰之眼」 ROG (Republic of Gamers) 也推出電競版無線路由器，在玩遊戲的時候保證遊戲的低延遲和網路穩定。

這是最新的 Wi-Fi 協議，近一年多，iPhone 11系列、三星 S10/Note 10系列、2020年搭載高通驍龍865的旗艦安卓手機、新的筆記本電腦等等，越來越多的設備開始支持，那對比上一代 Wi-Fi 5 到底好在哪裡？
真正意義上的支持「MU-MIMO」，其代表「多用戶、多輸入、多輸出」，允許路由器同時與多個設備進行上傳、下載的傳輸。Wi-Fi 5 路由器最多只能做到多設備同時請求下載，並且 Wi-Fi 5路由器只允許一次與4個設備同時傳輸，而 Wi-Fi 6 路由器可以允許8個設備同時進行上傳、下載請求。
Wi-Fi 6 路由器支持 160MHz 通道帶寬，數據傳輸帶寬更大，使得 Wi-Fi 6 最高理論速率可以達到 9.6Gbps，遠超上一代 Wi-Fi 5。
ASUS首批發布 Wi-Fi 6 無線路由器的廠商之一，從入門到高階，使用的晶元不同，網口數量，像高階的AX88U，提供了8個千兆網口，唯一可惜的是其接入網路的WAN口只是千兆，不過在次旗艦RT-AX86U上，卻提供了一個千兆WAN口和一個2.5G的WAN/LAN自適應口接入，4個千兆LAN口，其中兩個可以聚合輸出，連接NAS設備，保證最大2000M的網路傳輸。

傳統路由器 vs Mesh 路由器， 圖片來源網路在Mesh 路由器普及前，消費者會選擇購買電力貓，Wi-Fi拓展器等連接一個主無線路由器來擴展Wi-Fi的覆蓋面積，來滿足2-3層房屋的網路覆蓋。不過這帶來的問題是用戶在不同樓層需要手動切換信號最好的Wi-Fi。到了Mesh路由器系統，整套系統分享同一個Wi-Fi名字SSID，隨著用戶帶著網路設備移動，會智能切換，連接到信號最好，最近的一個節點路由器上面。一般是Mesh路由由一台主路由和多個節點路由器組成，大部分為1+2模式，如果需要覆蓋更大區域，只要再額外購買節點路由器，一般節點路由器的價格會比一台全功能路由器便宜，使得消費者可以以低價格添加更多的節點。
這裡建議消費者如果預算允許的情況下，盡量購買支持Wi-Fi 6的Mesh路由器。一次投資，保證未來幾年不落伍。
Amazon eero2019年Amazon宣布收購eero這家Mesh無線路由器生產廠商，想在智能傢具領域更近一步，與Google一較高下。不過，至少現在來看，Amazon 還沒有將erro打造成另一款類似ECHO一樣的爆款，並沒有在Mesh 路由器上領先其他競爭者。除此之外，Amazon早已經收購了無線攝像頭公司Blink，智能門鈴Ring，收購eero也算補齊智能家居在網路上的短板，配合智能語音助手Alexa，現在在智能傢具領域與Google，Apple三分天下，未來是否能完成「大一統」？令人期待。
除了提供無線路由器硬體產品，eero推出了保護網路的訂閱服務eero Secure，分為兩個套餐，普通的為每個月$2.99（年付$29.99），提供防止釣魚網站的訪問，兒童保護，廣告屏蔽，保護旗下設備免遭網路攻擊等，而高一級套餐eero Secure+為每個月$9.99（年付為$99），除了普通套餐提供的功能外，還額外附送1password密碼管理，encrypt.me VPN服務與Malwarebytes殺毒軟體的服務。
Amazon eero mesh WiFi system – router for whole-home coverage (3-pack)
- Whole-home coverage - an eero 3-pack is a whole-home wifi system that replaces your router and covers up to 5,000 sq. ft.
- Works with alexa - with eero and an alexa device (not included) you can easily manage wifi access for devices and individuals in the home, taking focus away from screens and back to what』s important.
- Works with your internet service provider - eero connects to your modem to bring your existing internet connection to every corner of your home.
華碩除了推出了與其他廠商一樣的Mesh路由器外，更研發了「黑科技」——Aimesh，用戶可以將2個支持Aimesh的全功能無線路由器組成一套Mesh 網狀網路，其優點是可以保證每一個節點都是一個高性能，全功能的路由器，支持的型號可以參見其網站。此解決方案可以讓用戶在搬家到大房屋后，無需拋棄現有的華碩路由器，購買Mesh路由器，只要再添加Asus路由器，組成Aimesh網路，購買成本降低了。

對於預算有限的用戶，或者整套公寓只有少數區域Wi-Fi信號不佳，那購買一個Wi-Fi Extender是性價比很高的選擇。放置在信號不佳區域與主無線路由器之間，將無線網路放大覆蓋原來的Dead Zone，不過缺點是無線網路速度會有損失。

將網路數據信號通過埋藏在牆壁中的電線傳輸，比較適合房屋較大，不方便在牆壁上打孔穿網線的用戶。一套電力貓有兩個設備，一個放在主路由器邊上的插座上（不要使用插線板，直接插在牆上），使用網線與路由器連接，而另一個可以放在不同樓層，將網路信號傳輸到Wi-Fi無法觸及的區域。但電力貓缺點也是比較明顯的，在同一條電線上盡量不要連接暖氣，微波爐等大功率設備，不然電力貓終端的網速衰竭的會很厲害，如果是舊房子，牆壁中的電線老舊，排布比較凌亂，也不太適合選擇電力貓。電力貓設備只能在同一個電網（同一個電錶）中使用，無法跨越到隔壁人家。

更加高級的「玩法」，比較適合在裝修前就確定網路方案，家庭面積大的用戶。之前這類解決方案在商業環境下用的較多，比如學校，醫院，商場等等。不過隨著家庭用POE （Power-over-ethernet）的交換機的普及，將入門門檻拉低。POE是指將電力通過網線傳輸，到終端Access Point，終端AP無需再額外連接電源，當然有些AP也提供電源介面。AP有分吸頂式的，還有裝在牆壁上的，類似電燈開關的面板式的，這個大家在裝修房子，布線的時候需要想清楚。選擇的網線也盡量選擇Cat 5e，Cat 6以上的網線，抗干擾性強。POE交換機除了可以連接網路AP，還能連接支持POE的攝像頭。
交換機可以設定每個AP的無線網路信號使用不同的通道頻道，避免互相干擾。當用戶在整個網路中移動，「漫遊」的時候，交換機會判斷用戶的設備連接哪一個AP可以獲得更好的信號與網路體驗。

「無線永遠不如有線」！如果搬新家，需要裝修，盡量在每個房間內都預留網線，隨著各種智能傢具越來越普及，將來升級網路，添加AP都會方便很多。我的建議是如果有能力，盡量買Wi-Fi 6的路由器。
