我最近买了一台安装了 Ubuntu 11.10 的 hp pavilion dm1。当我靠近路由器时,它可以检测到我的个人无线网络,但是当我在另一个房间时,它就无法检测到(除非我之前连接过),更不用说在我的大学了。有什么想法吗?

答案1
同一张卡也遇到了同样的问题BCM4313. 您没有使用正确的驱动程序(韓國),正确的驱动程序是韦。
安装专有的一个来自 Broadcom。
然后将/etc/modprob.d/黑名单.conf
blacklist bcm43xx
blacklist brcmsmac
blacklist bcma
blacklist b43
blacklist ssb
重新启动并检查:
lspci -k | grep wl
希望它对你有用,就像对我一样(信号非常强)。

将 contrib 和 non-free 添加到你的 source.list
/etc/apt/sources.list
