I want to get NIC info on a whole bunch of servers. Mainly what I'm interested in is speed (1GB, 100MB,etc.), and may be manufacturer & model.

I ran a script on my local machine using get-wmiObject Win32_NetworkAdapter, but I got this error:

Cannot process argument because the value of argument "obj" is null. Change the value of argument "obj" to a non-null value.

What am I doing wrong and more importantly how can I accomplish this?

TIA

 

What do you get if you run:

PS > get-wmiObject Win32_NetworkAdapter

That lists the NICs' name, MAC address, etc. among other things, but not its bandwidth/speed.

I found out that the command to get that information is:

Get-wmiObject -class Win32_PerfFormattedData_Tcpip_NetworkInterface

Thx for your reply!

 

Try these:

PS > [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces()

PS > [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces() | foreach {$_.GetIPv4Statistics()}

How do your get currentbandwidth on remote machine by using [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces()
Also if you are only trying to get the speed of those boxes that has IP enabled.
Thnx
