The answer is no. Qt does not have any functionality to get the device name (description). QNetworkInterface can only obtain the interface name and hardware address (IP).

On Windows you can use this small code example. pAdapter->Description should hold the value you are looking for.

#include <winsock2.h>
#include <iphlpapi.h>
#include <stdio.h>
#include <QCoreApplication>
#pragma comment(lib, "IPHLPAPI.lib")

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    PIP_ADAPTER_INFO pAdapterInfo;
    pAdapterInfo = (IP_ADAPTER_INFO *) malloc(sizeof(IP_ADAPTER_INFO));
    ULONG buflen = sizeof(IP_ADAPTER_INFO);

    if(GetAdaptersInfo(pAdapterInfo, &buflen) == ERROR_BUFFER_OVERFLOW) {
      free(pAdapterInfo);
      pAdapterInfo = (IP_ADAPTER_INFO *) malloc(buflen);
    }

    if(GetAdaptersInfo(pAdapterInfo, &buflen) == NO_ERROR) {
        PIP_ADAPTER_INFO pAdapter = pAdapterInfo;
        while (pAdapter) {
            printf("\tAdapter Name: \t%s\n", pAdapter->AdapterName);
            printf("\tAdapter Desc: \t%s\n", pAdapter->Description);
            printf("\n\n");
            pAdapter = pAdapter->Next;
      }
    }
    return a.exec();
}
