I just purchased a used DELL Inspiron 8200 laptop. I am able to connect to\nmy LAN without problems when not docked and with the network cable going\ndirectly into the laptop. If I dock the laptop in the Advanced Port\nReplicator, with the network cable connected to the proper port on the APR,\nthe network icon says that the network cable is disconnected. The lights on\nmy router come on OK.\n\nIn the device manager there is an item called "Ethernet Controller" under\n"other devices". This item does not appear in device manager when not\ndocked. Anyway, it shows that the Ethernet Controller is not working because\nno driver is installed. I haven't found a driver in any of the distribution\nCDs. The only driver on the DELL web site that might be applicable is\nalready installed on my laptop and is used by the 3-COM Network Adaptor\ncard.\n\nIs an "Ethernet Controller" needed when connected via an APR? If so, where\nwould I find a driver for it?
