I'm not really sure if I even want to do this, because I dont even know what a firewall really is, but my downloading speeds are really slow, and I'm trying to find the problem: -I have broadband internet that is pretty reliable, so thats not the problem. -I have an Airport Extreme Card linked to a linksys router in the other room, 20 feet or so away with walls in between. Could that be the problem? -Should I mess around with this firewall thing? -I'm downloading stuff on Bit Torrent, for the most part. I've checked the stat page that shows everyone's progress, and I'm one of the slowest, which tells me there must be something wrong with my computer. Bit Torrent uses ports 6881-6889. I don't know if they are firewalled or not, or whether that even matters. I'm pretty frustrated at this point, it's taken 7 days to download a show (DMB concert) all the way to 80%, and right now it's going at 0.5 KiB/s Well, I hope you can help, and thanks in advance!
