Well, I let the router try handling a re-download of DarthMod Empire, and it no likey. This after changing the settings and rebooting per the article @Xiahou found.

I think mebbe the simplest, cheapest solution would be to nab a cheap N-class router (with a reasonable amount of RAM), tart it up with DD-WRT, and call it a day.

I've already sunk too much time and thought into this problem. Time to plonk down thirty bucks and walk away whistling.
