Found in a network forum:
The biggest cause of lag is too much upload. Upload is the slower of the 2 and when you start to run out of upload bandwidth you have trouble sending responses(confirmation packets and whatnot) to the server causing lag.
The second one is a cheap(not always price wise) router(or old firmware) that has a low limit for connections. When the router runs out of connections(the number of computers it can talk to on the net, games may establish multiple connections to a server) it starts to just drop new ones, this sucks and has caused me to take back many a router. This normally only happens when using peer to peer sharing software as they make a massive number of connections.
Last thing to check is your routers firewall. Sometimes they are just too damn sensitive and start blocking stuff that should be allowed. _________________

Same forum: If you're using a linksys router i've found that enabling the SPI Firewall in the router causes Steam games like CS: Source and TeamFortress 2 to lag very badly. I checked the logs and it showed that the router was dropping the UDP packets because it thought they were a DoS attack when i was receiving, and it was dropping them when i sent them because it thought i was trying to DoS the server _________________
