I bought a trendnet wireless adapter for my iBook with Vista running on it. I installed the drivers and everything. I go to network settings and it says I'm connected to the internet but when I open IE every page I go to says some error. When I try to go to the iTunes store, it says to check my network settings. What should I do?
You're probably going to need to give more information before asking this.
First of all, what was the error?
Secondly, it might be that you don't have the right WEP/WPA code.
It might also be that you're still having driver troubles, check device manager to see if there are any problems with the device driver.
A simple shut-down might suffice as well.
