HP Pavilion G7 Notebook Will Connect Via LAN But Not Wireless

For over a month now my laptop has been unable to connect to the internet via a wireless connection. It will connect to the network, but that's as far as it goes. Resetting the router does nothing, and the same can be said for resetting the network wireless adapter. However connecting via the LAN cable to the Router will allow me to connect to the internet and use it normally.I've even tried deleting the wireless information for my network off the computer and re-inputting it but that didn't solve the problem either.I have an HP Pavilion g7 notebook PC that is running Windows 7. I got in it June 2012 brand new and have had nothing but problems with the wireless. It worked fantastic for the first few months and then this happened for the first time. I managed to fix it by myself that time, but I don't remember exactly what I did. It worked alright for the next few months but it was kind of spotty and temperamental. And now it's not working at all. I've tried everything I can think of to fix the problem but nothing has worked so far. According to the HP support Assistant my wireless adapter is called "Intel(R) Centrino(R) Wireless-N 1030"
