I have a wavecom modem with AT&T simcard in it and created a dialup connection in the XP computer.
I get connection errors 678 or 718 - “Remote server not responding” most of the time when I try to connect. Very rarely the connection was successful. The signal strength is always above 27 when I check using AT command. Any one help me to resolve this? And my AT&T account is in active state.
