interface Linkspeed

0

Hi, we have an HP G6 DL380 running window7 SP1, we have the Intel X520D-2 (10GIG NIC) installed, the OS & router both indicated link speed 10g full duplex, but the wireshark interface detail stated it's only a 1410mbps link speed. we are using wireshark version 1.11.2 Rev 53411 (64 bits) ; WinPcap 4.1.3

any suggestion ??

Thanks in advance Anh

This could be a driver problem or a WinPcap problem (from where Wireshark gets the information about the NIC speed), or even a Wireshark bug (which I don't believe).

To get closer to the answer, please post the output of the following commands:

dumpcap -D -M

plus

wmic NIC where NetEnabled=true list full

or

wmic NIC where NetEnabled=true get Name, Speed

Regards
Kurt

what about the wmic command (see my answer)?

here the wmic cmd:

O.K. as windows shows the correct value, it’s most certainly a WinPcap problem. Please report the bug to the WinPcap folks at www.winpcap.org
