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]: timeout set to 5 seconds

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

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

(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??


Here's an idea for Windows. I've not tried this, as
I have nothing I can rely on to generate log events.

http://www.i-helpdesk.com.au/index.p...ndows-ppp-logs


Run 'cmd' in 'startrun'

type 'netsh'

type 'ras'

type 'set tracing PPP enable'

[presumably, type 'exit' ???]

Look for C:\windows\tracing\, find PPP.log

And who knows, it might not work the same way in all Windows versions.

Since you have "No carrier" on Linux, that suggests
some module is missing to provide a driver. Or maybe
some "firmware" that needs to be loaded into the unit
during boot, that isn't happening. You could try, in
Linux, "lsmod" and review the modules in usage. Something
like that. Firmwares might be in /lib/firmware.
And run "dmesg" and review what is happening during
the boot process.

HTH,
Paul

Thanks for this, Paul. I'll report back.

Thanks, again, Paul. I did as the web page instructed and, lo and
behold, I've got a log ......

A bit worrying, though, that the log file seems to started a couple of
days ago as, at the top of my file .....

Could it be that Win7 is always writing this log and the instructions
given merely just make the file visible, effectively??

Might the log have been turned on previously ?

That's probably the easiest explanation.
