點解路由器咁重要?Why Your Router Matters
好多香港用戶都有一個經驗:明明申請咗 1000M 光纖寬頻,實際用 Wi-Fi 時得返幾百 M,甚至成日斷線。問題往往唔在寬頻本身,而係路由器。路由器係你屋企所有裝置連接互聯網嘅中樞,一個唔夾嘅路由器,可以令你嘅上網體驗大打折扣。
Many Hong Kong users have experienced this: you sign up for a 1000M fibre plan, but actual Wi-Fi speeds hover around a few hundred Mbps with frequent dropouts. The problem often isn't the broadband itself -- it's the router. Your router is the central hub connecting every device in your home to the internet. A mismatched router can drastically undermine your online experience.
Wi-Fi 標準比較:5 vs 6 vs 6E vs 7 | Wi-Fi Standards Compared
Wi-Fi 5 (802.11ac)
2013 年推出嘅標準,最高理論速度約 3.5Gbps(多條 stream 合計),但實際單裝置通常只能做到 300-800Mbps。目前仍然有大量平價路由器採用呢個標準。如果你嘅寬頻計劃係 100M-500M,Wi-Fi 5 路由器基本上夠用,但唔建議用於 1G 或以上嘅計劃。
Introduced in 2013, Wi-Fi 5 offers a theoretical maximum of about 3.5Gbps (combined across multiple streams), but real-world single-device speeds typically reach 300-800Mbps. Many affordable routers still use this standard. If your plan is 100M-500M, a Wi-Fi 5 router is generally adequate, but it's not recommended for 1G or higher plans.
Wi-Fi 6 (802.11ax)
2019 年嘅標準,最大改進係引入咗 OFDMA 同 MU-MIMO 技術,令多裝置同時連線時效能大幅提升。理論最高速度 9.6Gbps,單裝置實際可達 700Mbps-1.2Gbps。更重要嘅係,Wi-Fi 6 加入咗 Target Wake Time (TWT) 技術,可以大幅降低裝置嘅電池消耗,對手機同平板特別有益。呢個係目前性價比最高嘅選擇,適合大部份 1G 計劃用戶。
The 2019 standard's biggest improvements are OFDMA and MU-MIMO technologies, which dramatically boost performance when multiple devices connect simultaneously. The theoretical maximum is 9.6Gbps, with real-world single-device speeds of 700Mbps-1.2Gbps. Crucially, Wi-Fi 6 introduced Target Wake Time (TWT) to significantly reduce device battery drain -- especially beneficial for phones and tablets. This is currently the best value choice for most 1G plan users.
Wi-Fi 6E
Wi-Fi 6E 在 Wi-Fi 6 基礎上新增 6GHz 頻段,提供更多無干擾嘅頻道。6GHz 頻段目前使用者極少,所以信道非常乾淨,延遲更低,非常適合需要低延遲嘅應用如線上遊戲同視訊會議。不過要留意,6GHz 穿牆能力較弱,信號衰減比 5GHz 更明顯。如果你嘅屋企間隔較多,就要考慮路由器放置位置或配合 Mesh 使用。
Wi-Fi 6E adds the 6GHz band on top of Wi-Fi 6, providing more interference-free channels. Since very few devices currently use 6GHz, the channels are remarkably clean with lower latency -- ideal for online gaming and video conferencing. However, note that 6GHz has weaker wall penetration and signal attenuation is more pronounced than 5GHz. If your flat has many walls and partitions, you'll need to carefully consider router placement or pair it with a Mesh system.
Wi-Fi 7 (802.11be)
最新嘅 Wi-Fi 7 標準理論速度高達 46Gbps,引入 320MHz 超寬頻道同 Multi-Link Operation (MLO) 技術,可以同時利用 2.4GHz、5GHz 同 6GHz 頻段,大幅提升速度同穩定性。目前 Wi-Fi 7 路由器價格較高(一般 HK$2,000 起跳),而且需要支援 Wi-Fi 7 嘅裝置先至可以發揮全部功能。如果你訂購咗 2.5G 或 10G 寬頻計劃,Wi-Fi 7 係值得投資嘅選擇。
The latest Wi-Fi 7 standard boasts a theoretical 46Gbps speed, introducing 320MHz ultra-wide channels and Multi-Link Operation (MLO) that simultaneously utilises the 2.4GHz, 5GHz, and 6GHz bands for massively improved speed and stability. Currently, Wi-Fi 7 routers are pricey (generally starting from HK$2,000+), and you need Wi-Fi 7-capable devices to take full advantage. If you've subscribed to a 2.5G or 10G broadband plan, Wi-Fi 7 is a worthwhile investment.
100M-500M 寬頻 → Wi-Fi 5 已夠用
1G 寬頻 → Wi-Fi 6(最佳性價比)
1G-2.5G + 多裝置 → Wi-Fi 6E
2.5G-10G 寬頻 → Wi-Fi 7(面向未來)
Mesh 系統:大單位救星 | Mesh Systems: The Saviour for Large Flats
香港嘅居住環境千差萬別:有人住 300 呎劏房,有人住 2000 呎以上嘅獨立屋或複式單位。對於面積較大或間隔較多嘅住所,單一路由器往往無法覆蓋全屋。呢個時候,Mesh Wi-Fi 系統就係最佳解決方案。
Hong Kong living spaces vary enormously: from 300 sq ft subdivided flats to 2,000+ sq ft houses or duplexes. For larger or heavily partitioned homes, a single router often can't provide full coverage. This is where Mesh Wi-Fi systems shine.
Mesh 系統點樣運作?How Mesh Systems Work
Mesh 系統由多個節點(nodes)組成,每個節點之間互相通訊,形成一個無縫嘅 Wi-Fi 網絡。你嘅裝置會自動連接到信號最強嘅節點,而唔需要手動切換。相比傳統嘅 Wi-Fi Extender/Repeater,Mesh 系統嘅優勢在於:所有節點共用一個 SSID(網絡名稱),切換節點時唔會斷線;而且因為每個節點都係獨立路由器,速度損耗遠低於 Repeater。
A Mesh system consists of multiple nodes that communicate with each other to form a seamless Wi-Fi network. Your devices automatically connect to the strongest node without manual switching. Compared to traditional Wi-Fi Extenders/Repeaters, Mesh systems share a single SSID (network name), ensuring seamless handoff between nodes. And since each node is a full router, speed loss is far less than with Repeaters.
幾時需要 Mesh?When Do You Need Mesh?
一般而言,如果你嘅單位面積超過 700 呎,或者有三間房以上,又或者路由器同主要使用位置之間隔咗兩堵或以上牆壁,都建議考慮 Mesh 系統。對於 700 呎以下嘅單位,擺放得宜嘅單一高性能路由器通常已經足夠。
Generally, consider a Mesh system if your flat exceeds 700 sq ft, has more than three rooms, or if there are two or more walls between the router and your main usage areas. For flats under 700 sq ft, a well-placed single high-performance router is usually sufficient.

香港屋企路由器擺位攻略 | Router Placement Tips for HK Apartments
香港嘅單位普遍面積較細,但間隔密集,加上混凝土牆身同鐵門,Wi-Fi 信號衰減特別嚴重。以下係幾個實用擺位建議:
Hong Kong flats are generally compact but densely partitioned, with concrete walls and metal doors that significantly attenuate Wi-Fi signals. Here are practical placement tips:
1. 盡量放喺屋企中央位置 Place It Centrally
路由器嘅 Wi-Fi 信號係向四面八方發射嘅。如果放喺屋企一角,有一半信號就浪費咗。盡量將路由器放喺全屋嘅中心位置,例如客廳電視櫃附近。如果光纖入屋位置偏一側,可以用一條長啲嘅 LAN 線將路由器拉到中央位置。
Wi-Fi signals radiate in all directions from the router. Placing it in a corner wastes half the signal. Position it as centrally as possible -- near the TV cabinet in the living room, for instance. If the fibre entry point is off to one side, run a longer LAN cable to bring the router to a central location.
2. 放高啲 Elevate It
Wi-Fi 信號向下傳播比向上好。將路由器放喺架上或書櫃頂部(約 1.5 米高),可以改善全屋覆蓋。唔好放喺地板上或者藏喺櫃入面。
Wi-Fi signals propagate downward better than upward. Placing the router on a shelf or atop a bookcase (around 1.5m high) improves whole-flat coverage. Never put it on the floor or hide it inside a cabinet.
3. 遠離干擾源 Keep Away from Interference
微波爐、無線電話、藍牙裝置同其他電子產品都會干擾 Wi-Fi 信號。特別係微波爐運作時,會嚴重干擾 2.4GHz 頻段。同時,避免將路由器放喺魚缸、鏡子或大型金屬物體旁邊,因為水同金屬會吸收或反射信號。
Microwaves, cordless phones, Bluetooth devices, and other electronics interfere with Wi-Fi signals. Microwaves in particular severely disrupt the 2.4GHz band. Also avoid placing routers near fish tanks, mirrors, or large metal objects, as water and metal absorb or reflect signals.
4. 留意牆身材料 Mind the Wall Materials
香港公屋同私樓嘅牆身通常用混凝土或磚牆,信號衰減約 10-15dB。如果要穿過兩堵混凝土牆,信號會衰減得非常厲害。金屬門(尤其係公屋常見嘅鐵閘)更加係 Wi-Fi 殺手。如果你嘅房間有鐵門或金屬框架,強烈建議使用 Mesh 系統或有線回程(wired backhaul)。
Walls in HK public and private housing are typically concrete or brick, attenuating signals by about 10-15dB per wall. Passing through two concrete walls causes severe degradation. Metal doors (especially the iron gates common in public housing) are absolute Wi-Fi killers. If your rooms have metal doors or frames, strongly consider a Mesh system or wired backhaul.
各速度級別推薦路由器 | Recommended Routers by Speed Tier
100M 寬頻 | 100Mbps Plan
100M 寬頻嘅瓶頸在於寬頻速度本身,任何 Wi-Fi 5 或以上嘅路由器都可以輕鬆應付。預算有限嘅話,HK$200-400 嘅入門級 Wi-Fi 5 路由器已經足夠。推薦型號:TP-Link Archer C6(約 HK$300)、小米路由器 4A(約 HK$150)。重點係確保路由器有 Gigabit LAN 端口,而唔係只有 100Mbps Fast Ethernet 端口。
At 100Mbps, the bottleneck is the broadband speed itself -- any Wi-Fi 5+ router handles it easily. On a tight budget, an entry-level Wi-Fi 5 router at HK$200-400 is sufficient. Recommended models: TP-Link Archer C6 (~HK$300), Xiaomi Router 4A (~HK$150). The key is ensuring the router has Gigabit LAN ports, not just 100Mbps Fast Ethernet ports.
1G 寬頻 | 1Gbps Plan
1G 係目前香港最普遍嘅高速寬頻計劃。要透過 Wi-Fi 盡量接近 1G 速度,你需要一個 Wi-Fi 6 路由器,最好支援 160MHz 頻寬同至少 2x2 MIMO。推薦型號:TP-Link Archer AX73(約 HK$700-900)、ASUS RT-AX86U Pro(約 HK$1,500-1,800)、Netgear RAX50(約 HK$800-1,000)。呢啲路由器都可以喺近距離達到 800Mbps+ 嘅 Wi-Fi 速度。
1G is Hong Kong's most popular high-speed plan. To approach 1G speeds over Wi-Fi, you need a Wi-Fi 6 router, ideally supporting 160MHz channel width and at least 2x2 MIMO. Recommended models: TP-Link Archer AX73 (~HK$700-900), ASUS RT-AX86U Pro (~HK$1,500-1,800), Netgear RAX50 (~HK$800-1,000). These routers can achieve 800Mbps+ Wi-Fi speeds at close range.
2.5G 寬頻 | 2.5Gbps Plan
HKBN 同 HGC 等供應商都有提供 2.5G 計劃。要用盡呢個速度,路由器必須有 2.5Gbps 或以上嘅 WAN 端口(普通 Gigabit 端口會成為瓶頸)。Wi-Fi 6E 或 Wi-Fi 7 路由器係理想選擇。推薦型號:ASUS RT-AXE7800(Wi-Fi 6E,2.5G WAN,約 HK$2,000-2,500)、TP-Link Archer BE550(Wi-Fi 7,2.5G WAN,約 HK$2,000)。
ISPs like HKBN and HGC offer 2.5G plans. To fully utilise this speed, the router must have a 2.5Gbps+ WAN port (standard Gigabit ports become the bottleneck). Wi-Fi 6E or Wi-Fi 7 routers are ideal. Recommended models: ASUS RT-AXE7800 (Wi-Fi 6E, 2.5G WAN, ~HK$2,000-2,500), TP-Link Archer BE550 (Wi-Fi 7, 2.5G WAN, ~HK$2,000).
10G 寬頻 | 10Gbps Plan
HKBN 同 HKT 嘅 10G 住宅計劃係全球最頂級嘅寬頻速度之一。但要用盡 10G,挑戰非常大:你需要 10G WAN 端口嘅路由器、CAT6A 或以上嘅網線、以及支援 10G 嘅裝置。目前 Wi-Fi 即使係 Wi-Fi 7,單裝置嘅實際速度都好難超過 5Gbps。建議有線連接做主力,Wi-Fi 做輔助。推薦型號:ASUS ROG Rapture GT-BE98(Wi-Fi 7,10G WAN+LAN,約 HK$6,000-8,000)、Netgear Orbi 970(Wi-Fi 7 Mesh,10G,約 HK$8,000+)。
The 10G residential plans from HKBN and HKT represent some of the world's fastest broadband. But fully utilising 10G is extremely challenging: you need a router with a 10G WAN port, CAT6A+ cabling, and 10G-capable devices. Even Wi-Fi 7 struggles to exceed 5Gbps per device in practice. Use wired connections as the primary method and Wi-Fi as supplementary. Recommended models: ASUS ROG Rapture GT-BE98 (Wi-Fi 7, 10G WAN+LAN, ~HK$6,000-8,000), Netgear Orbi 970 (Wi-Fi 7 Mesh, 10G, ~HK$8,000+).
供應商提供 vs 自己買 | ISP-Provided vs Own Router
香港大部份寬頻供應商(HKT、HKBN、CMHK、SmarTone 等)都會隨計劃附送或租借路由器。到底用供應商嘅路由器定自己買?以下係利弊分析:
Most HK ISPs (HKT, HKBN, CMHK, SmarTone, etc.) include or lease routers with their plans. Should you use the ISP's router or buy your own? Here's the analysis:
ISP 提供路由器嘅優點 Advantages of ISP Routers
免費或包含喺月費入面,唔需要額外開支;供應商會幫你設定好,即插即用;遇到問題可以搵供應商技術支援。部分供應商(如 HKT)嘅高階計劃附送嘅路由器質素其實唔錯,例如 HKT 嘅 Wi-Fi 6 路由器或 HKBN 嘅 Nokia Wi-Fi 6 路由器。
Free or included in the monthly fee, requiring no extra cost; pre-configured by the ISP for plug-and-play convenience; technical support available if issues arise. Some ISPs (like HKT) provide decent routers with premium plans, such as HKT's Wi-Fi 6 routers or HKBN's Nokia Wi-Fi 6 routers.
自己買路由器嘅優點 Advantages of Buying Your Own
可以揀性能更好嘅型號;更多自訂設定(如 VPN、QoS、家長控制);唔受合約綁定,轉台時可以繼續用;長遠性價比更高。如果你對上網速度有較高要求,或者家中裝置較多,自己揀一個適合嘅路由器通常會比供應商提供嘅更好。
Choose a higher-performing model; more customisation options (VPN, QoS, parental controls); no contract lock-in -- keep using it when you switch ISPs; better long-term value. If you demand better speeds or have many devices at home, selecting your own router typically outperforms ISP-provided ones.
路由器設定優化技巧 | Setting Up for Best Performance
1. 分開 2.4GHz 同 5GHz SSID?Should You Separate SSIDs?
現代 Wi-Fi 6/6E/7 路由器嘅 Band Steering 功能已經相當成熟,建議用同一個 SSID 名稱,等路由器自動分配最佳頻段。但如果你發現某啲舊裝置(如舊款智能家電)經常連唔到或者斷線,可以考慮分開 SSID,將呢啲裝置固定連接 2.4GHz。
Modern Wi-Fi 6/6E/7 routers have mature Band Steering features, so using a single SSID and letting the router assign the optimal band is recommended. However, if older devices (like legacy smart home gadgets) frequently disconnect, consider separating SSIDs and fixing those devices to 2.4GHz.
2. 頻道選擇 Channel Selection
香港住宅密度高,2.4GHz 頻段非常擁擠。建議將 2.4GHz 設為自動選擇頻道,或手動揀 1、6、11 呢三個唔重疊嘅頻道。5GHz 頻段可以選擇 DFS 頻道(如 52-144),呢啲頻道通常較少人用。可以用 Wi-Fi Analyzer 手機 App 檢查你附近嘅頻道使用情況。
Hong Kong's high residential density makes the 2.4GHz band extremely congested. Set 2.4GHz to auto-select or manually choose channels 1, 6, or 11 (the three non-overlapping channels). For 5GHz, consider DFS channels (52-144), which are typically less crowded. Use a Wi-Fi Analyzer phone app to check channel usage in your area.
3. 更新韌體 Update Firmware
定期更新路由器韌體係最容易被忽略但又非常重要嘅步驟。韌體更新通常包含安全修補、性能優化同新功能。大部份現代路由器都支援自動更新,建議開啟呢個功能。如果你嘅路由器已經超過 3 年無更新韌體,可能係時候換一個新嘅了。
Regularly updating router firmware is the most easily overlooked yet crucial step. Firmware updates typically include security patches, performance optimisations, and new features. Most modern routers support auto-updates -- enable this. If your router hasn't received firmware updates in over 3 years, it may be time for a replacement.
4. QoS 設定 QoS Settings
如果屋企有人玩線上遊戲或者進行視像會議,建議開啟 QoS (Quality of Service) 功能,優先保障呢啲應用嘅頻寬。ASUS 嘅 Adaptive QoS 同 TP-Link 嘅 HomeCare QoS 都提供簡單易用嘅介面,唔需要專業知識就可以設定。
If someone at home plays online games or joins video conferences, enable QoS (Quality of Service) to prioritise bandwidth for these applications. ASUS's Adaptive QoS and TP-Link's HomeCare QoS both offer user-friendly interfaces that require no expertise to configure.
常見錯誤 | Common Mistakes
1. 將路由器收埋 Hiding the Router
好多人為咗美觀,將路由器藏喺電視櫃入面、鞋櫃後面或者閣仔入面。呢個做法會嚴重阻擋 Wi-Fi 信號。路由器需要「呼吸空間」,至少保持周圍 10cm 無遮擋物。
Many people hide routers inside TV cabinets, behind shoe racks, or in storage lofts for aesthetics. This severely blocks Wi-Fi signals. Routers need "breathing room" -- keep at least 10cm of clearance around them.
2. 用錯網線 Using the Wrong Ethernet Cable
如果你用緊 1G 或以上嘅計劃,但仲用緊 CAT5 網線,咁網線就會成為瓶頸。1G 計劃至少需要 CAT5e,2.5G 需要 CAT5e 或 CAT6,10G 就需要 CAT6A 或 CAT7。檢查一下由 ONT(光纖貓)到路由器嘅網線型號,呢條線印喺外皮上面。
If you're on a 1G+ plan but still using CAT5 cables, the cable becomes the bottleneck. 1G plans need at least CAT5e, 2.5G requires CAT5e or CAT6, and 10G demands CAT6A or CAT7. Check the cable from your ONT (fibre modem) to the router -- the category is printed on the cable sheath.
3. 唔重啟路由器 Never Rebooting the Router
路由器長時間運行會累積記憶體碎片,導致速度變慢或不穩定。建議至少每月重啟一次。部分路由器有自動定時重啟功能,可以設定喺半夜自動重啟。
Routers accumulate memory fragmentation over extended uptime, causing slowdowns or instability. Reboot at least once a month. Some routers have auto-scheduled reboot features -- set them to restart in the middle of the night.
4. 買貴唔買啱 Buying Expensive Instead of Suitable
唔少用戶花 HK$3,000-5,000 買咗一個旗艦級 Wi-Fi 7 路由器,但寬頻計劃只有 500M 同住緊 400 呎單位。呢個情況下,一個 HK$700 嘅 Wi-Fi 6 路由器已經可以完全滿足需求。路由器嘅選擇應該配合你嘅寬頻速度、單位大小同裝置數量,而唔係盲目追求最新最貴。
Some users spend HK$3,000-5,000 on a flagship Wi-Fi 7 router while on a 500M plan in a 400 sq ft flat. In this scenario, a HK$700 Wi-Fi 6 router would fully meet their needs. Router selection should match your broadband speed, flat size, and device count -- not blindly chase the newest and most expensive.
5. 忽略安全設定 Ignoring Security Settings
使用預設密碼、開啟 WPS、或者仲用緊 WPA2-TKIP 加密都係常見嘅安全隱患。建議第一時間更改管理員密碼同 Wi-Fi 密碼,使用 WPA3 或 WPA2-AES 加密,關閉 WPS 同 UPnP(除非你確實需要)。
Using default passwords, enabling WPS, or still running WPA2-TKIP encryption are common security vulnerabilities. Immediately change admin and Wi-Fi passwords, use WPA3 or WPA2-AES encryption, and disable WPS and UPnP (unless you specifically need them).
總結:點樣揀到啱用嘅路由器 | Summary: How to Choose the Right Router
揀路由器唔需要做科技專家,只要掌握幾個原則就可以作出明智嘅選擇:
Choosing a router doesn't require being a tech expert. Just follow these principles for a smart decision:
1. 確認你嘅寬頻速度,揀相應嘅 Wi-Fi 標準 Match your broadband speed to the appropriate Wi-Fi standard
2. 留意 WAN 端口速度(1G/2.5G/10G)Check the WAN port speed (1G/2.5G/10G)
3. 單位面積超過 700 呎考慮 Mesh Consider Mesh for flats over 700 sq ft
4. 確保路由器放喺中央、高處、無遮擋 Place centrally, elevated, and unobstructed
5. 核實網線規格配合寬頻速度 Verify Ethernet cable specs match your broadband speed
6. 設定好安全選項(WPA3、更改預設密碼)Configure security (WPA3, change default passwords)
7. 開啟自動韌體更新 Enable automatic firmware updates
