Dear All, I'm having trouble on 2 laptops Lenovo B580 since upgrading to Centos6.5. ( Because it's a Lenovo I cannot switch the network card for a better supported network card. ) There on the latest kernel : root at jac network-scripts]# uname -a Linux jac.cawdekempen 2.6.32-431.1.2.0.1.el6.x86_64 #1 SMP Fri Dec 13 13:06:13 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux With the help of the Elrepo Broadcom page I got the driver and that part works fine. The network card works : # vi /etc/udev/rules.d/70-persistent-net.rules # PCI device 0x14e4:0x4727 (wl) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="c0:14:3d:c1:f6:ef", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" # uname -a eth1 Link encap:Ethernet HWaddr C0:14:3D:C1:F6:EF inet6 addr: fe80::c214:3dff:fec1:f6ef/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:651 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:17 But I cannot connect to any wireless network with neither of the machines. I click on the gnome-nm-applet and type in the password.
