Delete all connection locations and redetect the modem

Completely deleting the sign on locations and connectivity files removes not only bad access phone numbers but also dialing options and incorrect modem or broadband settings. The AOL software will automatically search for and select the right connection device, and guide you through the process of selecting appropriate access phone numbers and dialing options.

WARNING: You will incur charges on your phone bill if you select an AOL access phone number that is a long-distance call or is not covered by your local calling plan. Please check with your local phone company to determine whether the access phone numbers that you select are local for your calling plan. Remember that members on certain plans may be charged an hourly rate for dial-up connections. See AOL Keyword: My Account for details regarding the charges applicable to your account.

Please click the link corresponding to the version of ACS on your computer for instructions to delete the connection locations and redetect the modem.
