'unknown' and big question mark on my network card

Hello
I get an 'unknown' with a big blue? on my map network between my computer and the router.
I already did the following:
Restarted
Reset router password
unchecked some v6 button
not all users connected
just abot all I've read about this.
It will go away for a period short and low and behold he came back.
What is it?
Why is that?
How can I get rid of him?
Thank you so much in advance.

I had the same big blue mark on several of my machines and know that the bonjour service is not installed on any of them - all clean installed Win7, Win2k8R2 and Win7Home.  The only thing they had in common was RealTek network cards (or at least that's how they are marked in Device Manager).

If your NETWORK card is a RealTek PCie or similar, you could try going to Device Manager and click on the Advanced tab of the RealTek network device.  There you should be able to navigate down to an entry labeled "priority and VLAN.  If activated, try to define this VLAN enabled.  I could do this fix on 3 of my machines with RealTek NIC and it seems that the problems of mapping network disappeared.

[I'm not saying that the bonjour service is not causing a? mark for others, but I got no Hello on my machines.]  The fix above eliminated the? all cards on all the machines in my network].
