I bought this router. And I have a problem with it. No matter with which the mining pool is connected shows 100% discarded packets.
Did you test it with the standard firmware on the Antrouter website using your Bitmain email first?

I would agree with looking at GUI on setup. Can you show us your screen with pool setup? That might help us see something wrong.
Also rich's comment is very good on knowing what firmware your using. As if you using the custom firmware you have a lot more options.
