No effect with the reset button. Once, I was thinking highly about the reset button, and, as a result, I tried it extensively, all the time, but I came to the conclusion that it doesn't do much to help. Ofcourse, I tried it now, but there is no sign of something being modified in the system. I'm pretty sure that it's something nvram-related, because the original fw works fine, only the web interface is broken and that appeared only after clearing the nvram.
