It seems like you read my original problem as slowness accessing the internet. That isn't the problem, I'm concerned about intra-LAN speeds. Haven't even got the length of worrying about internet speeds yet, since there are so many variables that can impact that, I have to be sure my end is in tip-top shape before I start poking at that.
