It is super broken (comparatively to Demon's Souls). Been that way since launch. PS3 and Xbox are a tad better. Best advice I could give if your trying to summon/be summoned would be to spam your sign every 30 seconds. It also depends on what area your trying to summon. The forest can be just about impossible. As for the PC open these ports on your router, this has worked pretty well for me. Good luck.
