Sign up with GoogleWhen I got home, I logged in under a different Windows profile and had to go through the same procedure to get the card working. To make sure the different profile is not the reason for the problem, I restarted again once I got the card working. Same story. Is this "normal"? I was hoping that your solution solves the issue completely, but it appears as if the frustration continues. It's ridiculous having to do this each and every time one needs to use the card after restarting one's laptop.

Hi, guys. Have just upgraded to 64K from 32K. Sim card worked fine for about 6 hours and then began to give problems with "no network available" - apparent problem with simcard - suggests input PIN number. However I have set the security settings not to request PIN each time I connect. Any idea how to change security settings to require me to input PIN every time?
hi bruceahibbert
A suggestion from this forum was to insert the SIM card into a "normal" mobile phone and disable the PIN from there. Once you use the SIM in the datacard it will not ask you for a PIN number...not sure if this is what you are after?
I have done the above and have not changed any settings on the dash...and no need to enter the PIN when the card initialises.

not sure if this will be of any help.
I've been playing around with my Novatel card on windows. As mentioned before there are 2 serials ports installed (on mine, COM7 and COM8). I've written a little app that when run, opens COM8, thereby initializing the Novatel device. I am then able to use my dialup connection to connect. All this is achieved without using that Dash at any point. The only problem I'm trying to figure out now, is how to get status messages from the card once connected (like AT+CSQ) since the COM8 port seems to be non responsive when trying to read from it
.
Anyone have any comments?

cyberbob, your little app is going to cause quite a stir if it can activate the Novatel card without the dash.
PM me with an e-mail, and I'll see what info I can find to help you get this working. If we can publish a dash-less utility for Novatel it'll help a lot of forumites.

I can verify cyberbob's idea.
I open my COM7 with a RS232 monitoring application (or write something in Visual Basic just to open COM7) and then use the Dialup profile of your choice to connect with a Novatel Card without the dash.
I'm connected without the dash currently and will leave it running 'till tomorrow and check for stability.

Re 619 error messages - I've just got these after about a month of blissful seamless surfing with a novatel U740. How annoying. I have no idea what's causing it. But on several occasions now, i have managed to connect after trying about 10 times and getting those damn messages. I get chucked out frequently too now. What's going on? Any suggestions?

Is this still happening? Some fixes did go in yesterday.
If you're still seeing the errors, try a GPRS-only and a 3G/HSDPA-only profile and post your experience.
Are you using a 32K or 64K sim? and how many bars on the dash?
I loose my downlink quite a lot, and then after trying to reconnect I get an error code (can't remember it, but it moans that the port is not responding). So after re-inserting the card, the entire PC crashes. This is quite weird and I hate pressing that reset switch. Sometimes I feel real bad because I have my games coding (link below) open and my files become corrupted when I reset, then I have to start what I was working on all over again
I surely hope that some fix comes out pretty soon, or that when I downgrade to a 3G card, that it is not a Novatel one

I just realised something, it seems that my card looses the downlink when I 'power use' it. What I mean is if for example I have mIRC, MSN Messenger, Firefox and Thunderbird (email) open all at once and all of them are trying to send data, my connection gets dropped. I have also noticed this when the connection first starts, I am sure that AVG tries to find updates, plus MSN Messenger is connecting and looking for updates and BOINC is also uploading completed tests.
Right now I have only been using Firefox and nothing else, and the connection seems very stable, it is also quite fast. So maybe if anyone else wants to try, you can disable all applications that are going to use the net (barring your firewall ) and see for how long your connection stays active.

From a network perspective, I'd rather expect the opposite, i.e. you've got a better chance of loosing the down-link if you don't exercise the link.
When there is no data flowing, the network puts your connection in an 'idle' mode and as soon as you start transferring data, you come out of idle.
Some subs got around this, by running a constant ping in the background and it resolved the issue.
This was a few weeks ago and we did find the problem and rectified it by tuning some parameters to resolve this so-called 'downlink-stop' problem.
Not impossible for some numbers to have slipped through the bulk update, so if you suspect you're seeing the same symptoms, (data going out, but nothing coming back), PM me your data card number (the mobile number of the sim inside the data card) and I'll have it checked out.
Hi Guys,
I am going to go with IC on this one. Sound rather like a IP stack/Driver problem. Maybe Deiphos can run some connection logger - something like Tiny Firewall or so that will show the number of active connections. As the card crashes, maybe run netstat -v (or is it netstat -a under Win) to see the number of open connections. They should, afaik, if the IP stack didn't crash, all show FYN_WAIT or something like that. That might only be true for the connections that are awaiting data. Idle connections might still be ESTABLISHED, but they will go into WAITING and then drop.
If the IP Stack crashed, they should all drop away - except for the LAN and loopback connections, but you can see that on the IP.
Laterz !

Well, v3g the number my card uses is 0823007580, I am not worried about it since I only use it for data.
I will see if I can get some loggers on my system to see exactly when the connection goes down. I had a look at my ZoneAlarm logs, but they say absolutely nothing about how many apps are trying to access the net. The funny thing that happens is this: when the card stops receiving data, sometimes vmc would crash (I have v7), if it doesn't I remove the card, and I hear the 2 chimes that windows makes (must be the two different ports it opens or something). Then if I am lucky I can re-insert the card and I hear the 2 chimes again and I can browse once more. If I am not lucky I will hear only one chime and then I have to restart the PC because VMC does not want to know a thing about detecting the card, if I am extremely unlucky the PC freezes there and then upon insertion of the card.
Another fact to mention is that if I insert the card and I only hear the 1 chime and try to restart, the PC freezes on the 'Windows is shutting down' message. I run Windows XP Pro SP 2.
