如何使Intersil ISL3887无线适配器工作
我有一个旧的无线适配器，我曾经在Ubuntu中使用，直到它似乎不再支持，我不记得确切的时间，但认为它是10.10左右的Maverick。
我刚刚把它挖出来，因为我的孩子的笔记本电脑无线网卡已经消失了。
Network-Manager看不到我的旧usb无线网卡。
做lsusb它显示：
Bus 002 Device 003: ID 1435:0427 Wistron NeWeb UR054g 802.11g Wireless Adapter [Intersil ISL3887]
此链接表明Linux内核仍然支持该设备
此链接提供了在Debian系统中启用设备的说明
有没有办法让它在Ubuntu 12.04 32bit中运行？
PS我试过sudo apt-get install linux-backports-modules-cw-3.6-precise-generic没有运气

驱动程序p54usb支持您的设备，该驱动程序需要固件。 请打开终端并执行：
sudo apt-get install linux-firmware-nonfree sudo modprobe -r p54usb && sudo modprobe p54usb
您的设备现在应该正常工作。
当你运行：
modinfo p54usb
它是否返回/lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/p54/p54usb.ko
或者它返回/lib/modules/3.2.0-36-generic/updates/cw-3.6/p54usb.ko
如果它是cw-3.6版本，那么backports没有完全删除，我们仍然有mac80211冲突。 请做：
sudo apt-get remove --purge linux-backports-modules-cw-3.6-precise-generic sudo apt-get remove --purge linux-backports-modules-cw-3.6-3.2.0-36-generic
确保一切都被删除。 通用软件包和匹配运行内核版本的软件包（在您的情况下，3.2.0-36-generic）都应该消失。
如果这不是问题，您可以重新安装包含所有驱动程序，mac80211，cfg80211等的linux映像。
sudo apt-get install --reinstall linux-image-`uname -r`
那些反引号在我的美国键盘的左侧与〜相同的键上。 重新启动，看看它现在是否正常工作。
