介紹瞭如何在linux環境下面使用電信3G卡,涉及相關驅動載入,常見錯誤debug以及相關配置.
工具/原料
中國電信3G卡
系統：CentOS 6.5
驅動：HW_Linux_Driver_4.19.19.00.tar.gz
方法/步驟
A.插卡後,執行 lsub 去檢查是否載入
B.然後檢視 /dev/ 下面有沒有 ttyU* 資訊,如果沒有的話需要安裝驅動
C.驅動安裝 [HuaWei_Datacard_linux_4.19.19.00.zip --> HW_Linux_Driver_4.19.19.00.tar.gz ]
1.解壓 tar zxvf HW_Linux_Driver_4.19.19.00.tar.gz
注意: 安裝的時候路徑如下 /tmp/keyring-5CJvtT/HW/ 會報錯 必須去掉後面的 '/'
[[email protected] driver]# ./install /tmp/keyring-5CJvtT/HW
D.lsusb 重新檢視 以及 /dev/ttyU* 檔案 ,如果有如下檔案 說明驅動安裝成功
E.撥號.
E-1.檢測硬體

E-3.如直接撥號,會提示賬戶未設定.
E-3.配置賬號資訊
編輯:/etc/wvdial.conf
E-4.開始撥號[建議重新插拔一下3G卡]

F.狀態檢查 okay （檢視是否能獲取到一個外部IP），然後隨便ping一個網站，比如 ping baidu.com
掉線自動重撥
--> 自動重撥機制 5s

--> The PPP daemon has died: A modem hung up the phone (exit code = 16)
--> man pppd explains pppd error codes in more detail.
--> Try again and look into /var/log/messages and the wvdial and pppd man pages for more information.
--> Auto Reconnect will be attempted in 5 seconds
注意事項
1.注意撥號資訊的配置(phone:#777 , username=card , password=card)
2.需要注意驅動是否載入
