Can not download any app from market

Nov 5, 2011
So this is my problem. I'm using nexus s with latest MIUI rom. I'm having problems downloading apps from android market. it just stops at downloading and that orange bar is full right from the start. I can download on other wifi internets but i can't at my home wifi. Its driving me crazy. I tried opening ports, singing in GTalk etc. etc...

Any ideas?
