「無法設定介面 wlan0 標誌 (UP):輸入/輸出錯誤」RT3290

「無法設定介面 wlan0 標誌 (UP):輸入/輸出錯誤」RT3290

我在 Ubuntu 上的 WiFi 卡遇到了一個非常令人困惑的問題。重新啟動後,它始終處於停用狀態,除了暫停或關閉筆記型電腦之外,沒有其他方法可以將其恢復。網路管理器顯示的狀態為「設備未就緒」。這種情況持續發生。

我的系統的一些背景:

  • 筆記型電腦是 HP 350 G1。
  • WLAN 卡是臭名昭著的 Ralink RT3290。 (如果我知道我會遇到多少麻煩,我就不會買它)。
  • Ubuntu是最新的LTS 16.04,最近升級了。
  • 核心是4.4.9-040409-generic4.4.0-22-generic在從主線升級之前 - 與 WiFi 沒有區別)。

在升級發行版之前,我使用了一個版本的rt3290sta/2.6.0.0驅動程式(從源代碼編譯並通​​過DKMS 加載),它的性能大部分都很好,但它不適用於較新的內核,而且似乎已經被放棄了。所以現在我不得不恢復rt2800並從那時起就遇到了這個問題。

這似乎是一個非常古老但反覆出現的問題。我通讀了我能找到的所有線索,但到目前為止還沒有運氣。幸運的是,這對我來說並不重要,因為我很少重新啟動,但至少它仍然令人煩惱和困擾。

以下是一些可能感興趣的命令的輸出(這是重新啟動後的狀態):

lshw -c network說接口被禁用:

答案1

驅動程式 rt2800pci 需要從裝置卸載韌體,該韌體在重新啟動期間仍然存在。在 Ubuntu 16.04 中,在重新啟動之前,您需要執行以下命令:

sudo rmmod rt2800pci

然後重新啟動。

為了自動執行重新啟動任務,請建立一個/etc/init.d/rt3290removedriver包含以下內容的 shell 腳本:

#!/bin/sh
### BEGIN INIT INFO
# Provides:          skeleton
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Example initscript
# Description:       This file should be used to construct scripts to be
#                    placed in /etc/init.d.  This example start a
#                    single forking daemon capable of writing a pid
#                    file.  To get other behavoirs, implemend
#                    do_start(), do_stop() or other functions to
#                    override the defaults in /lib/init/init-d-script.
### END INIT INFO

# /etc/init.d/rt3290removedriver

case "$1" in
   start)
       echo "Removal of driver rt2800pci success" > /home/youruser/rt2800pci.txt
       echo "Power Down" 
   ;;
   stop)
       rmmod rt2800pci
       echo "Removal of driver rt2800pci success" > /home/youruser/rt2800pci.txt
       echo "Power Down"
       exit 1
   ;;
   *)
       rmmod rt2800pci
       echo "Removal of driver rt2800pci success" > /home/youruser/rt2800pci.txt
       echo "Power Down"
       exit 1
   ;;
esac
exit 0

然後使用命令更新腳本

sudo update-rc.d rt3290removedriver defaults

你就完成了。將腳本中的 youruser 替換為您的使用者名稱。在配備 Ubuntu 16.04 和 rt3290 wifi pci 卡的 HP Pavilion 上進行了測試。

答案2

如果您有 Windows 雙重啟動,請嘗試載入 Windows,然後返回 Ubuntu。 Windows 往往會覆蓋某些筆記型電腦上的 BIOS 設定。

我的 ProBook 4540 也有同樣的問題,這解決了它。

當我載入帶有 Ubuntu 14.04 的 live USB 時,我產生了懷疑。我在網路管理員選單中看到了與安裝的 16.04 相同的訊息。

答案3

無法讓它工作。找到解決方案:

sudo ifconfig -a

將列出所有可用的乙太網路介面。現在透過以下方式啟動您的 WIFI 介面:

sudo ifconfig interface-name up
