Dont worry.. Christopher, You can always have your router back to factory's settings... to Do that you will need to

Find your ip Adress which is located on your router

After you found your ip adress.. go on your Browser

In your address Field where you normally type in www.__________.com replace that with your ip address including the dots between numbers

You should then see your Router's provider log in page, if you had never changed any of its settings then you should be able to find the log in information on your router

After you had Log in Browse around look for something that may change or restore your router back to its factory settings. There you have it your router would work like before

Hope this helped =D
