Laptop issue connecting to wireless internet but connects w/ LAN

Hello everyone,

I'm having an issue connecting to my wireless network with my computer. Things were working fine until a few weeks ago when the wifi on my computer stopped connecting; now I can only get internet through a wired connection (although the fact I can do this is strange to me). My rooommate is not having any issues with the wireless whatsoever. I have a fairly new acer aspire s7 which has no difficulties connecting to any other wireless network while I am at campus or have gone home for the weekend. I'm at a loss as to how to fix this issue as it has become impossible to do any form of research while I am at home. Any help would be greatly appreciated.

-Jay
 
Posibilities are your wireless signal is not in range or the wireless router is full of user who are connected to it, or it surpasses the user's limit.. how many user's has wifi connected to the wireless router?
