The last time you update your system, you can only connect your wired network to a wireless network. I usually even wireless network, did not buy cable. So check the wireless driver related issues, found that the update system caused by the wireless network card driver is missing. At first I thought it was the computer will be wireless disabled ...
So on the Internet under the wireless network card driver, I was under the hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz.
Wl.ko is generated after make
Then execute Insmod Wl.ko
This error refers to the fact that the dependent library of the module Wl.ko is actually caused by the following command to find the dependent library
If you know that the missing dependency is cfg80211, join it.
Then execute the Insmod Wl.ko, and now you can connect to the wireless network normally.
But there is also a problem that will not automatically load every time the system starts
Then add the following statement to the/etc/rc.local file.
