It seems like the combination of a somewhat dated Linksys WRT54G and the MacBook wasn’t made in heaven. Every once in a while, I find something like this in my laptop’s log files:

These effects occur once or twice a week, and aren’t really helpful in the middle of trying to work. Overall, this has the stink of a driver issue.
