Serious problems with Realltek Nic. Help!!



  • I have two realtek nics in my pfsense machine a pcie one and a onboard one. The problem is sometimes the two seems they are merged or having irq problems because if I get high latency on one the other shows high latency also. The other two nics in the machine which are two pci nics don't have this issue. So I am not sure if there is some conflict that's happening because they are both realtek cards.

    I have 3 wan connections.
    2 are the realtek cards onboard and pcie which is 1gbps card.
    1 is tp-link card.
    The lan is a davicom card.

    I was wondering if I buy another realtek pcie card and disable the onboard one would it solve the problem. I need some advice because I don't want to buy the pcie realtek card and it doesn't work.



  • Or you could purchase a $15 Intel NIC that doesn't have any issues.



  • i cant it isn't sold in jamaica i would have to order it online and its very hard to do so at the moment.

    Nobody can tell you that in advance with any certainty.  Unless they're really expensive where you are, I would try it just to rule that out.



  • Can you afford to take part of the network down ? If so try using one of your other known good NICs and confirm that it is or isn't a hardware issue before you buy a new NIC



  • ok i see
