reply from his ISP....
Is the house phone and computer on the same dial-up?
Yes, but I disable call waiting before going on line.
And I heard back from Juno:
Please do let us know if you have disabled the spyware programs running on your computer. Please note that the program like 'P2P Networking.exe' is an advertising program. This program is a registered security risk and should be removed immediately. These program can cause conflicts with the Internet connection.
I don't know how to do this, can anyone tell me? and..
Please disable the WAN (PPP/SLIP) Interface installed on the computer. Also, disable the Firewall program in the computer.
I have no idea what they are telling here..
I also suggest you to uncheck the first access number, and then verify if your problem is resolved. You can repeat this step with and every access number, until your problem is resolved. Through this way you will be able to find out good access numbers
