我无法使用装有 Ubuntu 13.10 64 位的 Dell Precision m4800 连接到 WiFi。
我在软件和升级中添加了推荐的“Broadcom Corporation BCM4352 802.11ac 网络适配器”，这样我就可以看到周围的 WiFi 盒了。
然而，无法连接到它们：身份验证总是失败。

自从我买了 M4800 以来，我一直在努力解决同样的问题。
虽然我希望下一个驱动程序能够解决所有问题，但我确实找到了一些有用的方法 - 至少有一点。不幸的是，它不是永久的，但可以让我的 Ubuntu Studio 13.10 在 3 次登录中的 2 次左右连接。
我遵循了此主题中的食谱：http://ubuntuforums.org/showthread.php?t=1783272&page=3
$ sudo gedit /etc/modprobe.d/blacklist.conf
只需添加：
blacklist mac80211
blacklist brcmsmac
blacklist cfg80211
blacklist wl
blacklist lib80211_crypt_tkip
blacklist lib80211
保存并关闭。然后打开：
$ sudo gedit /etc/rc.local
在出口 0 之前添加：
sleep 2
modprobe wl
保存。重启。下次登录时你的 wifi 可能会连接上。至少在 Ubuntu Studio 13.10 中是这样的。在 Mint 中我无法让它工作。
我希望这对某些人有用，至少暂时有用。
