New broadband members: Check if your service has been activated

When your AOL Broadband connection has been enabled, you will receive notification by email. Please check that you have received this email. If you have not received it, it is possible that the broadband connection is not complete yet.

Please note: It can take up to 14 working days from the date of order to get AOL Broadband set up.


Check your physical connections

Connection problems might be caused by something as simple as a loose connection to the modem, modem router or a filter. Check the connections are correctly set up as follows:


1. Unplug every device from your broadband-enabled phone line. Ensure to check every telephone point.
2. Locate the master phone socket and plug the filter directly into this socket.
3. Plug the DSL cable (the yellow line cable) into the DSL side of the filter.
4. Plug the other side of the yellow cable into your DSL modem or modem router.
5. Connect the DSL modem or modem router to the computer via the USB or ethernet cable provided.

Notes
-- For the best performance, we recommend that you always use your master socket and the DSL cable provided. Remove any extension cables that are present.

-- Any other telephony devices connected to the phone line, such as a burglar alarm, or Sky digital must also be connected via a DSL filter.
-- Ensure that no more than four telephone sockets, including the master socket, are in use.
