problem with network and NIC

[fibbina]

sorry for my english. J'have a big problema with network and with NIC.
My NIC is Realteck PCIe GNE family controller.
every time I turn on the computer is not connected to either network or internet.


I have to "play" on the NIC by disabling checksum values.
On the next reboot I do the reverse and enter the values that enabled RX or TX RX & TX enabled or enabled. The drivers are updated and are those of the manufacturer. How can I fix this? How should set the values of the checksum?
thanks

Fibbina:

As a first cut for a solution. There is the possibility that your NIC could be bad, do you have another NIC that you
could replace it with?
Another solution would be to go to My Computer, properties, device manager and uninstall the Network Card.
Then upon reboot, it would then re-install the Network card. You could take a look at Realtec and download a new driver.
