For 82574 please try script at http://sourceforge.net/projects/e1000/files/e1000e%20stable/eeprom_fix_82574_or_82583/ and see if helps with the issue. Also please check if your system has latest BIOS. -Tushar > >A general summary of the testing is as follows: >test 880,000 packets from transmitter to receiver >transmitter: >880,021 packets sent
