如何使Intersil ISL3887无线适配器工作

Question

我有一个旧的无线适配器，我曾经使用在Ubuntu，直到它似乎不再支持，我不记得确切的时间，但认为是大约10.10 Maverick。

我刚把它挖出来，因为我孩子们的笔记本无线网卡坏了。

我的旧usb无线网卡没有被网络管理器看到.

在执行lsusb时，它显示：

Bus 002 Device 003: ID 1435:0427 Wistron NeWeb UR054g 802.11g Wireless Adapter [Intersil ISL3887]

这链接表明该设备仍然受到Linux内核的支持。

这链接提供了在Debian系统中启用设备的说明。

有什么方法可以让它在Ubuntu12.04 32位中工作吗？

我试过没有运气的sudo apt-get install linux-backports-modules-cw-3.6-precise-generic

Answer 1

驱动程序p54usb支持您的设备，它需要固件。请打开一个终端并做：

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r p54usb && sudo modprobe p54usb

你的设备现在应该可以工作了。

Answer 2

当你跑步时：

modinfo p54usb

它返回/lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/p54/p54usb.ko吗？

还是返回/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并没有被完全删除，而且我们仍然存在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

确保所有的东西都被移除。通用包和匹配正在运行的内核版本的包，在您的例子中，3.2.036-泛型都应该消失。

如果这不是问题所在，您可以重新安装linux映像，其中包括所有驱动程序、mac80211、cfg80211等。

sudo apt-get install --reinstall linux-image-`uname -r`
