Problems with connecting to Internet via Linux but Win7Pro connectseasily.

I dual boot this HP 6730b Laptop with Win7Pro and Mageia Linux.

I can connect to the Internet on Win7Pro using my 3G USB Dongle but
cannot via the Dongle with my Linux .... at the moment!! It did, but not
now!!

I can see the Linux trying to make a connection, but it quickly gets a
"NO CARRIER" signal. In Linux, when it did work, the sequence ended like
this ....

Feb 23 19:51:38 localhost chat[15206]: AT+CGATT?^M^M
Feb 23 19:51:38 localhost chat[15206]: +CGATT: 1^M
Feb 23 19:51:38 localhost chat[15206]: ^M
Feb 23 19:51:38 localhost chat[15206]: OK
Feb 23 19:51:38 localhost chat[15206]: -- got it
Feb 23 19:51:38 localhost chat[15206]: send (ATDT*99***3#^M)
Feb 23 19:51:38 localhost chat[15206]: timeout set to 120 seconds
Feb 23 19:51:38 localhost chat[15206]: expect (CONNECT)
Feb 23 19:51:38 localhost chat[15206]: ^M
Feb 23 19:51:38 localhost chat[15206]: ATDT*99***3#^M^M
Feb 23 19:51:38 localhost chat[15206]: CONNECT
Feb 23 19:51:38 localhost chat[15206]: -- got it
Feb 23 19:51:38 localhost chat[15206]: send (^M)
Feb 23 19:51:38 localhost chat[15206]: timeout set to 5 seconds

(Note the fourth last line .... CONNECT.)

Again, on Linux, when it doesn't work, it ended like this ....

Mar 03 16:32:52 localhost chat[12336]: AT+CGATT?^M^M
Mar 03 16:32:52 localhost chat[12336]: +CGATT: 1^M
Mar 03 16:32:52 localhost chat[12336]: ^M
Mar 03 16:32:52 localhost chat[12336]: OK
Mar 03 16:32:52 localhost chat[12336]: -- got it
Mar 03 16:32:52 localhost chat[12336]: send (ATDT*99***3#^M)
Mar 03 16:32:52 localhost chat[12336]: timeout set to 120 seconds
Mar 03 16:32:52 localhost chat[12336]: expect (CONNECT)
Mar 03 16:32:52 localhost chat[12336]: ^M
Mar 03 16:32:52 localhost chat[12336]: ATDT*99***3#^M^M
Mar 03 16:32:52 localhost chat[12336]: NO CARRIER
Mar 03 16:32:52 localhost chat[12336]: -- failed
Mar 03 16:32:52 localhost chat[12336]: Failed (NO CARRIER)

(Note the third last line ... NO CARRIER.)

I am wanting to see if the signals sent to/received from the Dongle are
similar in Win7. Does anyone know where I might look to see what's going
on when I press the "Connect" button on the Win7 Wireless Broadband
Program?? Can I look at a file/log, somewhere, that gets written to when
making a connection or something??
