Changing wireless Settings on ATV2 w/o remote

i just moved back home from school and didnt bring my atv2 remote with me, ive always just used the app. However i didnt think that i would be on a different wireless network and now i cant access the settings on the device to connect it to my parents wireless network. is there anyway to access those settings that im not thinking of? can i hook it to my MBP and change it from there?

thanks

 

appreciate the response. i played around with itunes and found out that there is nothing there to change settings. Clemson is about an hour away from were i am now, so ill just drive over and pick up my remote when i get a chance.
