I have a compaq presario v2000. My ethernet port won't work. the wiresless works. I have a card that i can insert in the side of the laptop and hook a ethernet cable to, and it works. i thought the mini pci card may have been messed up, so i swapped it out, and still everything else works except the ethernet plug in. i've downloaded the realtec plugin, and still no luck. when i plug a cable into the ethernet port, the cable modem on my desk lights up like it is connected to the computer. i don't know what else to try. when i enable the connection with it plugged into the ethernet plug, it says that the connection has little or no connectivity. any help yall can offer is much appreciated.
