剛剛在 Acer Aspire S 上安裝了 Ubuntu 16.04,除了 wifi 之外,一切都運作良好。我可以連接到開放熱點,但當我對家中的 WPA2 路由器進行身份驗證時,它失敗了。
這是使用 Atheros QCA6174...

似乎身份驗證成功,但之後立即取消身份驗證?嘗試替換我的/lib/firmware/ath10k,如中所述https://askubuntu.com/a/718430/717711但這導致我的無線完全停止工作,因此恢復了這些變更。
不幸的是我現在有點難住了。幫忙表示感謝!

弄清楚了。 WPA 驗證適用於其他路由器,但不適用於我家中的路由器。需要明確的是...
- WPA 與其他路由器相容。
- 我的家庭路由器的 WPA 使用 Windows 運作。
- 我的家庭路由器的 WPA 可以與其他 Ubuntu 系統配合使用。
- 唯一的問題是 Ubuntu 的 Atheros 韌體和這個特定的路由器。
奇怪,但很容易修復。無論如何,這是一個舊路由器。 :)
