Hi all;

I have been trying to get my 5530 connected but I seem to be hitting a stone wall. At most, it connects once out of a few hundred (yes, hundred) tries.

I have tried the following
- Used all the modem scripts that I could find in this forum.
- Tape pin 20 (WWAN fix! thread)
- Updated my mini9 bios to vostro A90 bios to remove the pin 20 tape. (Taped it again to see if there was any difference-none)
- Flashed the 5530 modem with the AT&T firmware (New firmware to 7.2Mb).
- Checked if the SIM has SIM PIN. (SIM works fine in my iPhone BTW and there is no PIN)
- checked many times the APN (internet connects in the 1 of 100 times)
- Resorted to keying one AT command at a time (using AT cmd from Dell Wireless 5530 (aka Ericsson MBM F3705g) - AT commands reference).

I have noticed that the 5530 responds well to the following

AT
OK
AT+CFUN=1
OK

When it hits the PDP command, it almost for sure gives an ERROR.

AT+CGDCONT=1,"IP","internet"
ERROR

On the very rare occasion that it gives an OK, it will progress perfectly through the sequence to get connected and I can surf the internet untill I disconnect. Then the whole problem starts again.

I have tried powering down the modem /mini9 countless times and it has not shown any positive response.

Does anyone have any ideas why the modem behaves so? Any ideas on what else I could do? I might be missing anything? This digital device is behaving in a very analog fashion.

I am on OSX10.6.7. Network is Singtel or Starhub. Perhaps any others who are in Singapore can tell me if they are facing the same thing?

Thanks a bunch in advance for any suggestions.

Jay

Hey Jay,

got the same issues. First installation, everything worked like a charm. And after a while, I was not able to connect (ppp-error) to the internet anymore using wwan via the 5530 card.

I taped, i reeinstalled, I was trying to connect with at-commands. Nothing worked, it really frustrated me. So I tested one thing. I put back the sim into a normal Motorola (V9) and fired it up, waited till it´s got signal, then switched off, put the card back into my mini 9 and fired this one up.
And guess what? It worked. I don´t know wether it is a missing "reset" command that is needed after some time, but I think the sim card needed to be reseted. Just my thoughts.


Best, Felix
