Just installed the latest JD but now I cant get the Reconnect feature to work.
I have T2-B-Gawv1.4U10Y-BI modem and I am on a bridged mode.
Due to Bridged mode I have to manually reconnect the PC with a dialer.

Now if I reconnect the modem via JD, my modem/router would reconnect but my dialer wont connect automatically..

I did use "Create Reconnection Script" for my dialer (Disconnected it and reconnected) but when i tested it (Change IP) it worked once only but the 2nd time failed.

Or It may be a problem because I dont have a script for my modem

I found this:

@echo off
rasdial "NAMEOFYOURNETWORKCONNECTION" /disconnect
ping -n 20 127.0.0.1 >nul
rasdial "NAMEOFYOURNETWORKCONNECTION" "username" "password"

But is there any way so that I can change my IP without disconnecting the connection..?

No. A connection is defined by the IP address it connects to.
