新手求教：8187L网卡在linuxmint17下功率很低，经常断线！求大神们赐教～！
在WINDOWS 下讯号是满格的，都在95-100%之间！但是在linuxmint17下经常低于
70%导致断线，或者连接超时！
另外：我有网卡自配的linux驱动不知如何运行，已经折腾了一个礼拜了，真的想放弃！不过linux的界面和其他功能确实我很喜欢！

先安裝合適的驅動

sudo ifconfig -a
eth0 Link encap:Ethernet HWaddr 40:61:86:ca:fa:ba
UP BROADCAST MULTICAST MTU:1500 Metric:1
wlan0 Link encap:Ethernet HWaddr 00:25:22:49:29:1f
inet addr:192.168.1.116 Bcast:192.168.1.255 Mask:255.255.255.0

測試 有線網卡驅動時
把 無線網卡 關閉

補充
如果 有線與無線都能正常上網
同一時間 只能有一個網卡連上線
另一個網卡 會連上線後自動斷線 呈現待機
你的有線網卡驅動不是合適的驅動
所以你的無線網卡 可能跟著 時而斷線 時而連上線

沒有偵測到 無線網卡的 ID 號碼
所以 無法研判你硬體 品牌與型號
因此 rtl8187 是不是 合適驅動 無法確定
sudo lspci -nnvv # 兩個 n 兩個 v
如果是 USB 無線網卡
sudo lsusb -v
把 無線網卡 那一段 全部直接複製 貼上來
不要擷圖

感谢 poloshiao 大神的及时回复，我已经粘帖上来了！
另外：请教，我购买的台湾sopa大功率网卡（8187L）附送linux驱动，请问我如何更换附送的原装驱动呢？

台湾sopa大功率网卡（8187L）附送linux驱动
文件名：rtl8187L_linux_26.1040.0820.2010.release.tar.gz

http://download.modem-help.co.uk/mfcs-R ... tar.gz.php
1. 這個驅動 猜測 是適用於 Linux kernel 2.6 的 舊版本

configuration: broadcast=yes driver=rtl8187 driverversion=3.13.0-24-generic firmware=N/A

idVendor 0x0bda Realtek Semiconductor Corp.

2. 根據你的 Linux kernel 版本 下載合適的驅動檔案
http://drvbp1.linux-foundation.org/~mcg ... backports/
https://www.kernel.org/pub/linux/kernel ... ts/stable/

3. 進一步參閱
3-1. http://wireless.kernel.org/en/users/Drivers/rtl8187
3-2. http://wireless.kernel.org/en/users/Download

rtl8187 LevelOne WNC-0301USB v5 0x0bda 0x8187

4. 如果你使用早期的 Linux Kernl 版本 <= 2.6.12
參閱
http://rtl8180-sa2400.sourceforge.net/

5. 安裝妥適驅動後 再
sudo lshw -numeric -class network
看看 有沒有抓到正確的 ID 0bda:8187

[ZSDC]

非常感谢！ poloshiao 老师的指教！再请问：如何删除原有的全动再安装新的驱动呢？谢谢！

[poloshiao]

如何删除原有的全动再安装新的驱动呢

1. 驅動 一般是 驅動模組 方式 被載入
只要把 驅動模組 rtl8187 列入載入黑名單 即可
http://askubuntu.com/questions/110341/h ... el-modules
2. 如果新安裝的 驅動模組 名稱完全一樣
那舊的 驅動套件 最好是先移除
移除方法 要看你原來安裝的驅動套件的來源及方法

感谢 poloshiao 老师在早上六点钟这么早就给我回复，真的很感动！UTUBUN精神，在这里得到体现！我回继续专研下去的！再次感谢！

RTL8187！传说中的蹭网卡用的芯片，听说功率超级大，信号超级好？

没感觉 搜到的信号不少 但是 信号质量都很差
