How To Setup Your DSL Modem.
1)If you have rebooted the modem and it doesn't log back in you can check the settings in the modem. If it is a Zoom modem there are 2 IP addresses that you can use to log in and check the settings. In the top of the address bar type in http://192.168.1.1 or http://10.0.0.2 and it will bring up a username and password. The username will be "admin" and the password should be "zoomadsl" If not try "admin" for the username and "admin" for the password.
2)If you have a Netgear modem the URL is usually http://192.168.1.1 or you can try http://routerlogin.net. The username is usually admin and the password is password.
3)If you have an Actiontec modem the URL is http://192.168.0.1 and you can follow the instructions here: http://support.actiontec.com/doc_files/GT701D_NCS_Ethernet_DSL_Modem_User_Manual-v1.0_126.96.36.199.1.pdf
4)Once you log into the modem make sure that the Protocol is set to PPPoE.
5)VPI should be set to 0 and VCI should be set to 35
6)The username will be your home phone email@example.com and it should look like this as an example: firstname.lastname@example.org
7)The password will be "password" all lowercase.
8)Once those settings are in the modem click the Save/Apply button. In older modems choose Save Changes then click Write Settings to Flash.
