Isn't NetZero dialup....?
If you use their DSL service instead, I'm guessing you can get better service from a local ISP. You still need the DSL circuit from the phone company, but they don't really tell you that you can use anyone you want (that supports it...) as your ISP. For people in the Twin Cities with DSL, you should switch to Visi.com. Best company, bar none. For other areas, talk to your IT department and see what the techs there use for DSL.
