    Hoping someone can suggest something here for me. I was running bios 402 and decided to upgrade my RAM and Harddrive and switch to windows x64. So not wanting to have to go through the process of registering again I used the ssv3 and andys tool to give me a 702 version of bios. I loaded the original 702 and then then modified one. Everything works fine except there is no long a nic!! In windows it says it can not start the adapter with error code 10. In windows the lights on the nic turn off just after the windows logo. If I load ubuntu and try and manually start the NIC I get "RTNETLINK answers: Cannot assign requested address" however the NIC lights are on and flashing. However, while the lights are flashing it also says that there is no cable plugged into the ethernet port. However there is. I've seen messages else where that the realtek drivers can manage to dissociate the PHY layer so I trie unplugging the machine and taking the CMOS battery out left it for an hour and rebooted....but got the same thing. I've tried reverting to 0402 firmware but it has the same issues. I'm gathering that this is something to do with Realtek but simply can't get it to the start where it wishes to reattache the PHY layer again. Anyone else come across this?

    This is insane. I've downloaded the DOS diagnostic programs and it reports that the NIC is fine and passes everything. However neither ubuntu or windows like it to be able to communicate with my router. I've looked at if each end is trying to be MDIX and it getting it wrong but there is no control apparent in the windows driver to lock it. Ubuntu says there is no cable plug in. Since it used to work perfectly i'm assuming that it didn't just happen to go bad at a bios update. Return to the original windows and it does not like it either. There are many issues on realtek ethernet cards going missing for no apparent reason. I think I've joined those ranks.

    Freaky stuff. Static IP I can ping the other hosts on the segment. However DHCP simply does not work on windows or ubuntu. If I set to DHCP it appears that the message doesn;t actually get to the wire at all because the router never see's the DHCP broadcast at all. Any one have any suggestions. (Guess not since nothing to date).

    Convinced that there is something with the EEPROM flashing on the RLT8168D on the board but can't figure out the corrcet commends to reflash using pg8168.exe from

    http://translate.google.com.au/tran...T&rls=org.mozilla:en-US:unofficial&prmd=imvns


    Which provides all the programs to reflash realtek drivers. Either that or mine is just had it. The pg8168 /r shows the correct MAC SVID and SMID but adding the /efuse gives a incorrect MAC address. I don;t know whats the correct value here. Anyone else with a P5G41C-m LX want to try and tell me what you get from

    pg8168 /r
    and
    pg8168 /r /efuse

    and tell me if the are the same?

    i think the mac addy got wiped. try to find your mac address in router logs or in the registry from prior settings or on the board usually on a sticker starts 00#######
    to flash it back

    well thats my problem. If I use PG8168 /r it gives me a MAC address. However a PG8168 /r /efuse says may MAC address is 00 00 00 00 00 30 which is wrong. I'm not sure that the PG8168 is giving the correct results for the board. If I try and program the MAC back to the Efuse component it tells me its full. Not sure which is right or wrong. If someone has another board and could tell me that would be great. Thanks

    Good Morning!

    I've had the same problem:
    The ethernet card is connected to the local network (and can see other computers on the same network) but I do not surf the internet.
    Realtek card makes me mistake with the usual yellow exclamation point ....

    If you also have a Realtek ethernet card you can try to solve the problem by reprograming the (reflash) internal eeprom memory of your card.

    How to proceed:


    1) Download these * .zip tools (available for download at Asrock):

    http://www.asrock.com/support/Download/MACTool.asp

    - mac117f_T.zip
    - mac161B.zip
    - mac207A.zip


    2) Download Rufus:

    http://rufus.akeo.ie/

    - Make a USB PEN BOOTABLE (Dos Boot)


    3) You have to try every single archive until you find the "software programmer" that will serve in your case.
    - Put the unpacked archives in the bootable usb key.


    4) Reflash MAC ADDRESS:

    - PG8168.EXE /efuse /nodeid XXXXXXXXXXXX (where xxx.... is your new mac address)
    - or try
    - PG8168.EXE /nodeid XXXXXXXXXXXX
