Thank you Aegis and Broni . This forum is super awesome.
<3 Your replies were so quick, too! :D
Aegis:
It is connected wirelessly, and I do update my drivers, so I
was sure it wasn't the cause.
Broni:
My laptop worked after doing that Command Prompt method.
Sometimes I feel like such a noob. -__-;
I thought it wasn't going to work, though, because it kept on
saying something about elevation(?), up until ipconfig /renew.
Thanks again! ^__^;
