LAST EDITED ON Dec-11-01 AT 08:42 PM (GMT)the first problem is from ur ISP .
the second problem U can solve it by decrease the max speed of the port try to put it ( 38400 or 57600 ) if U like to do this go to start - settings - control panels - modem ( in the general tab ) and in the same dialog box but in the ( connection tab ) double check if ( wait for dial tone ) is not checked .
the third problem U can solve it by refresh ur network componente ( tcp/ip , clients for microsfot network , and dial up adapter ) U should remove them and reinstall them again ...in this case U need to have the CD
