You can logon to router to reconfigure it. First of all connect your computer to the router. Turn on router. On the router you will find some information as follows:
ip address: For example 192.168.1.1 (may be different for your router)
username: For example admin
password: For example password
They are normally written on the router. You will definitely need these three information. There are ways to find these information if you can't find them. For example by ressting the router and then referring to the manual of the router for default user name and password. You can download a manual of the router from manufacturer's website.
Now start internet explorer or any other browser. Type the ip address of the router in the address bar. For example type 192.168.1.1 in the address bar.
It will prompt you for username and password. Once you enter the username and password you will see a lot of settings. Go through it. All settings are self explanatory. Only thing that you will need to change is the username and password.
Ask AOL for new settings. Like username, password, etc.
Once you enter the correct settings save the settings.
Hope this helps.
