this is probably the most annoying problem i've ever had...

currently, i use a direct diaup ISP to get online for both gamecube games. however, about 5 days ago, ep I and II started having an issue signing online where it seemingly took longer to authenticate my username and password and then couldn't find the DNS server. using the same memory card and ISP settings, i can get online just fine on ep III. i requested DNS numbers from my ISP so as it wouldn't have to search for them, and still the problem (and ep III still works great). got any ideas as to what might be causing the problem?

if which ISP i'm using has anything to do with it, i'm currently using Outdoors Unlimited. it's funny, 'cause when i asked for the DNS numbers from them, they had no idea what a gamecube was, haha. dummies... anyhow, any help is appreciated. thanks.
