我的電腦有問題，它透過 wifi 連接，但瀏覽器無法載入網頁。在 Windows 7 中，問題仍然存在，因此可能是硬體問題。我怎樣才能檢查這個？連接到相同網路的其他無線設備運作正常。我已經格式化了電腦並重置了路由器。
路由器型號：sitecom N300 x4 計算機：acer aspire 5750g（ubuntu 15.04 / windows 7）
如果我使用有線連接（乙太網路），效果很好。
以下是一些資訊：

編輯：如果我不打開 youtube，連接會更穩定，並且可以長時間保持連接，但如果我打開影片或類似的東西，它會停止加載新頁面。

如果此問題在 Windows 中仍然存在，則不是 Ubuntu 問題。這要么是硬體問題，要么是您的無線環境問題，或者只是訊號強度低。
嘗試靠近您的路由器。如果您附近有太多無線網路使用該頻道，則更改路由器設定中的頻道也可能解決該問題。
