HUSABER Posted April 30, 2013 Share Posted April 30, 2013 The all "F"'s is not a valid MAC address. That is considered a broadcast frame and your NIC should never get an IP from your router if that's the case.Sometimes your (non-wireless) NIC ends up with a MAC address of 00:00:00:00:00:00 / FF:FF:FF:FF:FF:FF / 04:4B:80:80:80:03 after a BIOS update. This effectively makes your NIC useless until you can fix it. On some boards this will cause a 'MAC address are invalid in both CMOS and Flash' error. You need to get that address changed. And so,you patch BIOS?Error is from here :wink2: (For me,you need to Flash your NIC with EEPROM.EXE(DOS),to use corectly Mac Address Link to comment Share on other sites More sharing options...
toanbk Posted May 1, 2013 Author Share Posted May 1, 2013 I don't know why I have to flash my NIC with EEPROM.EXE ?, because in windows 7, I use Lan connection normaly. Link to comment Share on other sites More sharing options...
