I'm pretty sure its my Linksys router. I draft fine when i'm plugged directly into the DSL modem.
I've got Verizon DSL with a Linksys WRT54G Wireless rounter, have the Desktop computer plugged right into it, using the split option since my wife uses the router wirelessly. I can draft, be drafted and hold in a 5-6 player game with no problems.
Make sure to look under your security settings, make sure the router firewall is off (how many firewalls do you need running at once, anyway?). If you set port forwarding, and still have problems, try running it in DMZ mode(found under "gaming applications"). Note: You can't have it set for DMZ and Port forwarding at the same time, so make sure you disable the port forwarding before trying to run it in DMZ mode.
If it still doesn't work...throw the router out and tell everyone else you need the mainline for your computer...
