wifi平時無事,notebook一連就斷線

Unable to determine as:

1. A lot of information is missing, like models;

2. You have not clearly mentioned when the WiFi is impacted, are other devices impacted as well.

In the mean time, you can try to reinstall your driver to the latest version and try to disable your Bluetooth and see.

What exactly are you using?

情況有點像 notebook 中了毒, 然後不停攻擊 router 和其他連到 wifi 的裝置, 霸佔所有 wifi 網絡資源.

以前試過有朋友遇到同樣的問題, 一部機中毒, 隻毒向整個網絡發出大量垃圾 signal, 拖跨成個 network, 所有機上唔到網.

簡單來講, 掃毒吧.

也有另一個可能, 是 notebook 裝了大量 BT 或 "大陸免費睇戲" 軟件, 例如風行 / pps 一類. 呢 d 軟件會係背景執行, 就算你無用緊無睇緊戲到會霸佔大量 bandwidth, 如果你同時安裝幾隻的話, 也有機會拖垮成個 wifi 的.

如是第二個原因的話, 就 uninstall 部份較少用的睇戲軟件吧, 世上無免費午餐的.

你先關上所有裝置，關掉router，重開，再開手提，如無異樣，才開其他裝置。
