I installed ndiswrapper, and tried to use the Windows driver to activate the Broadcom 1505 802.11n wireless card on RHEL, but failed. 1. Add line 'alias wlan1 ndiswrapper' to /etc/modprobe.conf 2. # system-config-network Add the wireless card and try to activate it. But the error message pops up: "ndiswrapper device wlan1 does not seem to be present, delaying initialization." I checked dmesg and found no failure message related to bcmwl5 or ndiswrapper. But the wireless card could not be detected by hwbrowser. I successfully used Broadcom 1390 802.11bg wireless card on SLED at one time or another, via the help of ndiswrapper. Can you please provide any suggestion?
