I did both in response to a friend downloading a a multi-gig game on my 
home net and completely slagging the network. Hilarity ensued as I tried 
to figure out what was going on for about an hour. I haven't managed to 
actually reproduce exactly the way he did it, but from everything I've 
tried I've not been able to cause my connection to melt down like that 
again.

For this, I bought a new router and flashed it with openwrt. At first I 
didn't think it made any difference because I didn't realize that I 
needed actually enable it. Is there some reason it's not loaded and 
enabled by default?
