Not yet, anyway.
Anytime you hear a drowning sound it’s definately connection related. Remember that the Orangebox engine is extremely unforgiving of an unstable or lossy internet connection and even a 10ms loss can take 500-2000ms to recover from. Rather than treat it as a temporary loss and readjust the game world based on data from the next server tick, as the old HL2/CSS engine did, it completely flushes the game world and redownloads the entirety of it from the server. On populated TF2 and any L4D this can take a LONG time. In L4D2 it’s not unusual for a 5-10ms server “hiccup” to take 10-15 seconds for everyone to catch up.
Are you using campus wireless? If so then yeah, that’s definately the problem. Even with 4 bars their wireless connections are unstable at best.
