I tried to look into this but so far I wasn't able to find any solution as the 
way we're retrieving the NIC name is the one recommended by the official 
Windows documentation.

For posterity, problem is here:

Also, another note: on my Windows 7 box the NIC gets listed but its name is 
truncated after encountering the first unicode character (whereas you state it 
is not listed at all - are you sure about that?).

Yup, I'm sure. Maybe try re-encode the string or add an option to strip unicode 
characters?
In my case NICs with unicode characters simply doesn't appear in the returned 
list, they aren't counted into overall stats too.

Does ipconfig /all show the NIC?

Yes, of course.

No, sorry. I'm also pretty swamped lately because of a new job so I won't have 
time to dedicate to this issue (and psutil in general to be entirely honest).

The problem is here: 
https://code.google.com/p/psutil/source/browse/psutil/_psutil_mswindows.c?name=r
elease-1.2.1#2260

The Py_BuildValue able to decode only the UNICODE characters.
I made the following path to replace these characters with "_".

    while (pCurrAddresses) {
        py_nic_name = NULL;
        py_nic_info = NULL;
>   int i;
        ...
        sprintf(ifname, "%ws", pCurrAddresses->FriendlyName);
>   for (i=0; i<100; i++) {
>     if ( *(ifname+i) < 0 || *(ifname+i) > 256 ) {
>        // Replace the NON UNICODE character
>        *(ifname+i)='_';
>     }
>     if (*(ifname+i) == '\0') {
>       // end of friendly name
>       break;
>     }
>   }
        py_nic_name = Py_BuildValue("s", ifname);

@g.rodola: can you put this patch into the next release?

Despite this is a dirty hack I couldn't find any better solution so I committed

Thanks.
