I've experienced this problem on two different computers. In both cases, it had to do with the selected sign on location, and the sign on options associated with that selection. The options vary from version to version, and they have made some changes lately, so it is hard for me to be specific. If you are using a router (which was the case in both cases I encountered), then the appropriate sign on option is Home Network or ISP/LAN. You should not select DSL. You also need to verify the sign on options associated with the location, and the locations are just names and can be anything you want
The following pertains to AOL 9.0
1) select the location that you think is correct if you have more than one location
2) select Sing On Option
3) select Expert Setu
4) click the + in front of the location name. I only have one location. If you have multiple locations, I think they may all be listed, so make sure you select the + in front of the correct location
5) look at Devices under Broadband Connectivity. If more than one device is listed, go down to Order Devices are Used and verify that they are in the proper order. If not, you can change the order or delete unused devices.
6) If you aren't sure about settings, select Add Device, Manually Add Connection Device, and then look at the list of options. Like I said, if you are using a router, Home Network is the correct selection. If not, then the correct selection is probably AOL Broadband with DSL
Hope this helps (and makes sense). If not, reply and I'll try to clarify.
