I have just bought a Dell Inspiron 1510 and loaded Fedora 12 along with Windows. I cannot detect any wireless networks through my network applet on the tool bar.
$:lscpi 12:00.0 Network controller: Broadcom Corporation Device 4727 (rev 01) 13:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
I installed the following rpms:
kmod-wl-220.127.116.11-127.fc12.i686.PAE-18.104.22.168.3-3.fc12.6.i686 kmod-wl-PAE-22.214.171.124.3-3.fc12.6.i686 broadcom-wl-126.96.36.199.3-1.fc12.noarch
and restarted the system but it still doesn't work.
