Hello, pc.. Compaq Armada E500.. windows 2kp..this pc card with RJ-45. http://www.cqout.com/show.asp?u=http://184.108.40.206/SB/3Com_3C589C_tp.jpg is loaded and drivers installed (no longer have disc) device manager says ..this device is working properly yet there is no light on the adapter and hence no internet connection. I have changed settings to see if that would help and this is strange, when I set the transceiver value to.. TP (RJ-45).. Local area Connection Network cable unplugged pops up! and when I change the value to the other option.. Coax (BNC)..Local Area Connection connected Speed:10.0 Mbps pops up!.. but still no connection to internet, router working and cables secure. Don't know what to do at my wits end can you help please . Kind Regards.
