Nothing. Yep, absolutely nothing.
It is normally a bad idea to optimize a connection for "download speed" or even ping time. A game like AH depends on connection quality foremost, and if you tweak your connection for "download speed" sometimes you do so at the expense of quality.
The only thing I would even consider doing is making sure your MTU is set properly. However, Win98SE automatically adjusts it unlike Win95 used to. I don't think you have to mess with it.
If it ain't broke, don't screw with it.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
