This is a strange problem which started when the local exchange was upgraded to broadband (I live too far to receive this). I can no longer connect to aol on my desk top,on my computer line, either no carrier or number busy. I can connect with my lap top on this line. I can connect to aol on a second line (not strictly mine!) and also connect with my lap top on this second line. Do any of you whizz kids know how this can occur? So my modem is working and my phone line is working, just this connection problem on the desk top.
