May I know the current firmware version on your WR941ND? You can check that on the management admin page of the router.
And what's the language displayed on the management page?

You have to show us Status tab from TP-Link and what is your problem with BCS?

What's BCS?

The main problem i have right now is that I after the first login on management page, after 10 minutes, router reject my connection and I can't connect again because whenever i try to connect at 192.168.1.1 it say that my conection is refused. I can't connect again by any device until I restart the router by disconnecting the wire.
