I have never seen that particular error message, but here are my first few thoughts:
For one, if possible, I would always try gaming on a network cable rather than via wireless. Your connection will be faster, smoother, and more stable; your pings will also be lower. Even if the signal strength is good, you will still have at least some packet loss and possible interference.
Do you notice the problem on some servers but not others? High pings, and of course lags from packet loss, often trigger servers to drop players. Could be something along those lines.
However, if you switch to a line and still have the same problem, perhaps it's a client-side issue? Just to be sure, you might try uninstalling STEAM, deleting the folders, and making a fresh install.
