I wish I could give you my so called terrible internet aka Australian quality UK Internet. Youd love it for DQ since DQ doesn't care too much about internet speed compared to other applications which is why I liked it , even when I had worse internet's.
I feel sorry for you though. What's your net speed. Mine is 1-2mbps which isn't fast but it's workable for DQ and website usage and maybe 480p videos on YouTube but that's it. I had much worse before though.
