I have an hp compaq laptop with a marvell yukon 88E8042 fast ethernet controller. For some reason, when i try to connect via the utp-lan cable, the port leds won't turn on port nor do they turn on on the router and I cannot connect to the internet...I am trying to understand why. Is there a possibility that the port has stopped working? Any ideas please?
You could have a bad network cable, or a bad port in either the router or laptop. I would try a different cable and then different ports on the router. If that doesn't work then I would say you might have a bad port on the laptop. In rare instances a driver might cause an issue but you would see the lights come on when you boot the pc but shut off when Windows gets going.
Thanks for the quick reply! I have tried with different kinds of cables, routers and internet connections even. I haven't succeeded with any, unfortunately. I tried what you proposed, shut down and reboot but the lights do not come on, at all. Is it possible that there is something wrong with the port?
I would check into the network driver. It could be that the driver you have installed for it isn't working correctly. Normally when the system first comes up and sees the networking device and then gets disabled it is because of a bad driver.
You might want to remove the driver in safe mode and then reboot to see if it comes up and works while it is installing the new driver.
