首先,我的笔记本电脑(Lenovo b575)在过去几天内能够成功连接到 WEP 和 WPA2 网络,但性能一直不稳定。当接口做过工作时连接会随机断开。现在它根本不起作用。
见见我的$uname -a

运行 Slackware 14.0。
lspci -v

好的。让我们
lsmod | grep rt

不应该rt2800pci
使用?嗯...也许如果我
$dmesg | grep rt2800
...

你好... 最后一句dmesg
似乎是一个很好的线索。一点点搜索ing 让我相信我可能有一些冲突的驱动程序。我如何找出我应该考虑将哪些驱动程序列入黑名单?我的研究得出了一些(看似)相互矛盾的观点,即哪个驱动程序最适合我的内核版本和网络控制器。
帮助我理解,StackOverlords!
=================================更新===================================== 根据 Henrik 的建议,我尝试将 rt2800pci 驱动程序列入黑名单,以取代 rt2860sta 驱动程序。然而……
#find /lib/modules/$(uname -r) -name rt2860sta.ko
没有结果。我推测这意味着 rt2860 驱动程序未包含在 Slackware 14.0 iso 中,对吗?
