笔记本无线网卡有用吗？BCM4311

好的，我有一台 Acer Aspire 5517，它有 bcm 4311 802 无线网卡，Ubuntu 12.04.3 LTS

网络控制器：Broadcom Corporation BCM4312 802.11b/g LP-PHY（rev 01）

以下是输出sudo lshw

我试过这个安装 Broadcom 无线驱动程序没用。对于 chili55，我这样做了

    $sudo apt-get remove --purge bcmwl-kernel-source
    E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
    E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

答案1

我假设，尽管您无法确认，但此命令：

lspci -nn

...显示您的无线设备为 14e4:4315。如果不正确，请发布结果。如果正确，请获取临时有线以太网连接并执行以下操作：

sudo apt-get remove --purge bcmwl-kernel-source

如果没有安装，没关系，只需执行以下步骤：

sudo apt-get install firmware-b43-lpphy-installer

重新启动并告诉我们您的无线是否正常工作。
