...that was more work than the port scan method I was using. Talked to the big cheese from the youth ministry upstairs today and we'll go through the two computers on Friday. It's a given that someone's always downloading music at the coffeehouse. You see the kids in there all the time with their headphones on. I'm not sure that was the problem so much some uploading going on. I know there's some rogue software floating around upstairs because IMMEDIATELY upon filtering the two MAC addresses, our bandwidth was freed according to that highly-scientific method of observing the blinking indicator lights on the modem.

I used to have an office from which I shared my DSL connection to two other small offices. One night my bandwidth was slowed to 26k (that's slower than Ye Olde 56k Modem!) so I started unplugging cables from the router (there was no wireless there). When I unplugged the realtor down the hall, my bandwidth jumped to 600k (normal). Plugged it back in and after five minutes I was back down to 91k and dropping. Unplugged him again and I jumped back up to 600k. Left it that way then followed up with him the next day. He was running Kazaa as a server and leaving the computer on all night. I wouldn't be surprised if something like that was going on up there, or maybe a trojan/worm like Bagle or Netsky.

Thanks.
