Write a question about the following article.

GAH . I ca n't really express how frustrated I am at the moment . We got a wireless router for our cable internet modem , and got it all hooked up , and then I went in and tried to change the network name and it got all fucked up and now I ca n't sign in to the network , and the only way any of us can get internet is to plug directly into the router . Which sucks .

Question:
What may be the reason that changing the network name is giving so much trouble ?
OPTIONS: A. With the name changed , they need to change the name of their computer as well .. B. With the name changed , the network authenticity is challenged .. C. None of the above choices .. D. With the name changed , they need to put their settings back to default ..
