我有戴尔 inspiren 1564，今天我在 ubuntu 上安装了最新版本。安装成功完成仅用了 10 多分钟，然后我更新了它。现在一切都运行良好，除了 wifi。我在互联网上搜索了一下，并按照论坛上给出的一些解决方案做了，比如反向移植，我已经按照这个 AZ 做了 关联
当我在终端输入这个命令时，它给了我
frank@frank-Inspiron-1564:~$ iwconfig
eth0 no wireless extensions.
lo no wireless extensions.
我已经尝试过这个并得到答复：
frank@frank-Inspiron-1564:~$ sudo apt-get install firmware-b43-lpphy-installer
[sudo] password for frank:

E: Unable to locate package firmware-b43-lpphy-installer
我现在应该怎么做 ;
按下这个命令后我得到了这个列表：

答案1
您的设备需要固件。在网络连接正常的情况下，打开终端并执行以下操作：
sudo apt-get update
sudo apt-get install linux-firmware-nonfree
重新启动后你的无线网络就能够正常工作了。
如果您无法从 Ubuntu 存储库获取软件包，请尝试：
wget http://mirrors.kernel.org/ubuntu/pool/multiverse/l/linux-firmware-nonfree/linux-firmware-nonfree_1.14ubuntu1_all.deb
sudo dpkg -i linux*.deb
然后重新启动。
您需要删除有冲突的 backport 包：
cd ~/backports-3.16-1
sudo make uninstall
重新启动并再次检查日志是否有错误：
dmesg | grep b43
iwconfig
答案2
您有一个 BCM4312。
方法 1
你可能只需要下载并安装这个 DEB 文件。它包含 BCM 文件。它也比该linux-firmware-nonfree方法更可靠，因为它破坏其他东西（例如图形驱动程序）的可能性较小。
