With DirecWay, you really have to tweak:

Hopefull with a little luck your download speed will increase to about where mine is. (1500-3000 Kbps depending on the time of day, and sometimes up to 6000 Kbps.)
Don't expect your upload speed to increase at all.
How are you set up? A single computer? Multiple networked? DW6000 or 4000? OS, specs of all machines?
Post back with this info, and I'll try to help more.
