Hi there,
I have managed to get the Sony Ericsson GPRS GC89 card to connect to the
T-Mobile GPRS network in Linux 2.6.15 and I got messages like these from
pppd :

But I am apparently still not on the internet. Pinging anywhere doesn't
work. However, I can successfully send SMS messages when I log onto the card
using minicom and playing around with AT commands
I was hoping to consult with everyone on what might be the problem here. Did
I miss a specific step?
Thanks in advance!

Have you looked through the Sony Ericsson AT Commands manual and
properly set up your card to connect with your service provider?

how does your routing table (route -n) look like after the ppp connection
has been established?

That tells you that the routing table hasn't changed. So I assume that
everything is still routed to eth0. I don't know what the right parameter
for pppd would be to change this behaviour, but just for testing purposes,
you could try taking down eth0 first, check that the routine table is
empty, and then connect with pppd - it should write the right routing
table if no default route exists.

where is the IP?

Re: GPRS card connected to the GPRS network in Linux 2.6.15, can send SMS messages, but still no internet?
Hi Sven
yes, it is indeed a problem with the routing table, thanks. The connection
process is unable to modify the routing table for some reason when my
Ethernet is plugged in or enabled. I disabled the Ethernet, re-ran the
connection script, the routing table does gets modified and now the
connection works.
However, the connection is rather unstable for some reason. I observed that
if the network bandwidth gets too high(like around 113kbps) , the modem will
hang up and the connection will terminate. Then if the script tries to
reconnect and gets to the point of executing the AT+CGDCONT commands, I see
a CME Error 3 which means operation not allowed. I will then minicom to the
card and then try to do AT+CFUN=1 to reset the card, but after I execute
that command, everything else i execute afterwards will give a CME Error 513
which means Link Layer Error apparently
I am wondering if this has something to do with how I wrote my Connection
Script. The card connection is not this unstable when used in XP.

Unless I'm mistaken, your "AT+CGDCONT" needs to be executed once
only, when you first set your device up for your particular
carrier. That setting should then persist through sessions and
power-ups indefinitely.

Re: GPRS card connected to the GPRS network in Linux 2.6.15, can send SMS messages, but still no internet?
Hi John
I believe you are right, but when pppd is going to do a reconnection after
getting disconnected, it will just call the same connect script. This means
those AT+CGDCONT commands will inevitably get called again.
Is it possible to just jump straight to dialing ( "ATD*99***1#" ) during a
reconnection? Is this the right thing to do anyway?
Thanks!

That's what I do (Linux kppp dialer). Otherwise only an "ATZ"
command gets executed in my GPRS setup (Wavecom external modem
attached to /dev/ttyS0).

Re: GPRS card connected to the GPRS network in Linux 2.6.15, can send SMS messages, but still no internet?
Yea, ATZ attempts to restore the card to the factory settings.
But sometimes if I get disconnected, and then I try to even do ATZ, I still
get a CME Error 513
By the way, is there a GUI version of a ppp program for Gnome? I think KPPP
is for KDE
Thanks

Just in case it matters at some stage, "ATZ" restores the
default configuration (which needn't be factory defaults - you
can make certain changes, and use "AT&W" to write them).
"AT&F" is the command to reset to factory defaults.

Have you tried the "AT+CGACT?" command to check your attachment
status? Or the "AT+CGACT=0,1" command to specifically
deactivate the current session prior to trying again?

I didn't find one when I looked around on my system for it some
time ago. I'm fairly sure I read about something once though.
Maybe someone else knows.
