升級到 Ubuntu 13.10 後，我的筆記型電腦中的 Ralink RT3290 Wi-Fi 轉接器無法運作。所以我按照指南如何讓 Ralink RT3290 無線網路卡正常運作？編譯驅動程式並手動載入。看來模組已成功加載，因為我得到了以下輸出：
forever41200@forever41200:~$ lsmod | grep -in rt3290sta
26:rt3290sta 1170462 0
forever41200@forever41200:~$ modinfo rt3290sta

depends:

但Ralink RT3290 Wi-Fi 轉接器所使用的驅動程式並沒有改變。它仍然使用“rt2800pci”而不是“rt3290sta”。

所以我將“rt2800pci”和“rt2x00pci”添加到黑名單中，我還更新了initramfs。但它仍然沒有使用“rt3290sta”。它說 Wi-Fi 適配器正在使用“rt2860”。

這很奇怪，因為我在系統中找不到“rt2860”模組。
forever41200@forever41200:~$ lsmod | grep -in rt2860
forever41200@forever41200:~$ modinfo rt2860
ERROR: Module rt2860 not found.
然後我將“rt2860”添加到黑名單，但什麼也沒發生。
使用“rt2860”模組，Wi-Fi 適配器一開始可以工作，但幾分鐘後整個 Linux 系統崩潰了。我收到的錯誤訊息是：
它提到了“rt3290sta”，這讓我更加困惑所使用的驅動程式是“rt2860”還是“rt3290sta”。
順便說一句，將“rt2800pci”和“rt2x00pci”添加到黑名單後，Ralink RT3290 Wi-Fi 適配器不再命名為“wlan0”；它被命名為“ra0”。
答案1
刪除rt2800pci
sudo rmmod rt2800pci
加載新的
sudo modprobe rt3290sta
發布任何錯誤訊息。
如果新模組 rt3290sta 在啟動時無法正確加載，則幾乎肯定需要將 rt2800pci 模組列入黑名單。
