Getting my Pc to work again
 

I recently changed my broadband to virgin from B.T.
Problem is when installing my new router I forgot about my PC which is in another room and as I can no longer wire my PC to my hub I now have no network it and cannot use it for internet connection.
I am not really computer savvy so any simple explanation would be welcome.
Please Help.
Thanks !
I didn't find the right solution from the internet.
