New computer - Dell Inspiron 15R laptop. Windows-7 home premium 64-bit. Trying to access internet. 7 gives connection option of Broadband where ISP requires ID and Password. However, my ISP does not require this info to log on....its just "plug-n-play" I have run every test and diagnostic that I can find and the only prob I can find is something to do with the DNS, but have no way to fix the problem. The connection is Cable Modem, via LAN wire. One of the diagnostics recognizes my ISP, but still won't let me connect. Any suggestions will be greatly appreciated.
