DSL troubleshooting

  1. Good Morning I hope you can help me with my question. I have a Cisco 827 ADSL router. The dsl line went down the other day. I still was able to ping the internet because we have a backup line so when I did a trace ip; it showed it was going out the other line. The DSL line is back online now; but when I do a tracert still it shows it going out the other line; If I change my gateway( on my pc) I'm able to go out the DSL line but I need to know how can I force a "ping" to go out the DSL line so I could know whether is down or not? or how would you approch this issue to find out if DSL is down?

    Thank You.

    forcing a path is not possible.

    whatever program we use, we connect to the socket and then SEND packets.
    The SEND will route traffic according to the routing table
    (see yours using run->cmd /k route print)

    the important like is the DEFAULT GATEWAY address; unless your target is on your
    LAN (where traffic will flow there), getting outside your system is via the default gateway.

    How to change the default gateway?
    disconnect all devices from the router and disconnect any dial-up connection.
    wait 30 seconds.
    reconnect the link you wish to become the default
