播放卡頓，通常唔係盒子壞咗 / Buffering Usually Isn't a Faulty Box

電視盒子播放時出現卡頓、緩衝或者畫面停頓，絕大部分情況同網絡環境、路由器位置或者裝置設定有關，而唔係硬件故障。以下十個方法由最常見、最容易解決嘅開始排列，建議由上而下逐個試。

Buffering, stuttering or pauses during playback are, in the vast majority of cases, caused by your network environment, router placement, or device settings — not by faulty hardware. The ten fixes below are ordered from most common and easiest to resolve, so work through them from the top.

1. 檢查實際網絡速度 / Check Your Actual Internet Speed

高清串流建議下載速度最少 25Mbps；4K 內容建議 50Mbps 以上。留意「合約速度」同「實際到達電視位置嘅速度」可以差好遠，建議喺電視附近用手機測速。

We recommend at least 25Mbps download for HD streaming, and 50Mbps or more for 4K. Note that your contracted speed and the speed actually reaching your TV can differ substantially — test with a phone next to the TV.

2. 改用 5GHz WiFi 頻段 / Switch to the 5GHz WiFi Band

2.4GHz 頻段容易受微波爐、藍牙裝置同鄰居 WiFi 干擾。如果路由器支援雙頻，將電視盒子連去 5GHz 頻段通常即時見效。

The 2.4GHz band is easily congested by microwaves, Bluetooth devices and neighbouring networks. If your router is dual-band, moving the box to 5GHz often produces an immediate improvement.

3. 縮短同路由器嘅距離同阻隔 / Reduce Distance and Obstructions

牆壁（尤其混凝土）、金屬家具、魚缸都會大幅削弱訊號。可以嘗試將路由器移到較開揚位置，或者將盒子同路由器擺喺同一層。

Walls (especially concrete), metal furniture and even fish tanks significantly weaken WiFi. Try relocating the router to a more open position, or keeping the box and router on the same floor.

4. 重啟路由器同電視盒子 / Restart Both Router and TV Box

將路由器斷電 30 秒再開，同時重啟電視盒子。呢個簡單步驟可以清除暫存問題同重新分配網絡頻道，解決咗相當比例嘅卡頓個案。

Power off the router for 30 seconds, then restart both it and the TV box. This clears temporary glitches and lets the router reselect a cleaner channel — it resolves a surprising share of buffering cases.

5. 減少同時連接嘅裝置 / Reduce Simultaneous Devices

如果屋企同時有人下載大檔案、打機或者其他裝置串流 4K，頻寬會被分薄。試吓喺卡頓時暫停其他裝置嘅活動，睇吓有冇改善。

If someone is downloading large files, gaming, or streaming 4K elsewhere in the house, bandwidth gets divided. Pause other devices during playback and see whether the problem disappears.

6. 檢查並釋放儲存空間 / Check and Free Up Storage

儲存空間接近爆滿會拖慢整個系統反應。建議定期清理唔再使用嘅 app 同快取檔案，保留至少 15–20% 可用空間。

Storage close to full slows the whole system down. Clear unused apps and cached files periodically, and try to keep at least 15–20% of storage free.

7. 保持系統同應用程式更新 / Keep System and Apps Updated

舊版本可能存在已知嘅效能問題或者兼容性 bug。定期檢查系統更新同 app 更新，通常可以解決一啲難以定位嘅間歇性問題。

Older builds may carry known performance issues or compatibility bugs. Checking for system and app updates regularly often resolves intermittent problems that are otherwise hard to pin down.

8. 非必要唔好開 VPN / Avoid Unnecessary VPN Use

VPN 會將流量繞經額外伺服器，必然增加延遲同降低速度，係卡頓嘅常見成因之一。另外請特別留意：本裝置不得喺中國大陸使用，亦不得連接任何中國大陸網絡（包括 VPN）。

A VPN routes traffic through an additional server, which inevitably adds latency and reduces throughput — a frequent cause of buffering. Please also note: this device is not to be used in mainland China, nor connected to any mainland China network (including via VPN).

9. 考慮改用有線網絡 / Consider a Wired Connection

如果裝置支援乙太網接口，有線連接幾乎必定比 WiFi 穩定，特別適合客廳位置固定、又追求 4K 穩定播放嘅用家。

If your device has an Ethernet port, a wired connection is almost always more stable than WiFi — particularly worthwhile if the box sits in a fixed position and you want reliable 4K playback.

10. 最後手段：還原出廠設定 / Last Resort: Factory Reset

如果以上方法都試晒仍然卡頓，可以喺設定入面選擇「更多」→「重置」，將裝置還原至出廠狀態再重新設定。還原前請記低你嘅設定同已安裝 app。

If none of the above helps, go to settings, choose "More" → "Reset" to restore factory defaults, then set the device up again. Make a note of your settings and installed apps first.
