Sniffer doesnt sniff *sniff*

[dsfargeg]

Okay, I read Himred's "What to do when sniffer doesn't sniff" post, and did everything, but I still can't figure out what's wrong.. the last thing the post says, is "If all else fails, your card is unsupported", but I've got the "Realtek RTL8139 Family Fast Ethernet Adapter" and it's a pretty normal card.
I get the blowfish key and everything, but it just doesn't want to sniff anything.. Any FURTHER suggestions?

I found the problem: I was behind 2 routers.. I went to only one of them, and it all works now..
