The Novatel 'remembers' the last profile you attached with. Not sure if it's relevant to this topic (only read the last post...), but I found if you want to use 'dash-less' management on Windoze, you need to first select the profile with the VMC and then any DUN setup will connect with that profile.
 
Hey redarrow,

I looked at it and found two commands that are send to the Novatel:

Code: 
AT+COPS=3,2
and
AT+COPS=0,2,"65501",2

Now, the first command is un-documented in the sense that the +COPS command can only be =0 or =1. Here is what I would like you to try.

1) Replace the current COPS command with AT+COPS=0,2,"65501",2
2) Replace the current COPS command with AT+COPS=1,2,"65501",2
3) Replace the current COPS command with AT+COPS=3,2

And lets see :)

Laterz !

Hey Tazz_Tux,

I keep on meaning to mention this..

It appears that the "3gonly" thing (aka AT+COPS) doesn't work on the Novatel Merlin U740..
Or at least it has no effect.. when connecting with it enabled my data card still happily jumps around from GPRS through to HSDPA... :confused:

I only remembered this again cos I'm away from home and I can pickup 3G here...

However ... it appears not all cards are the same.

My brand new HUAWEI E620 card doesn't appear to like the last argument...

Code: 
AT+COPS=3,1
OK
AT+COPS?
+COPS: 0,1,"VodaCom",0
AT+COPS=0,1,"VodaCom",2
TOO MANY PARAMETERS
AT+COPS=0,1,"VodaCom"
OK

Weird!

Appears my house has no GPRS or higher access, can't get a carrier from here so not been able to test out the speeds or anything else.

Got the AT's on how to setup 3G or HSDPA?

Hey WildPikachu,

Your first failed command has AT+COPS=1 while the second is =0. Try this command:

AT+COPS=1,1,"Vodacom",2

:)

Hey Tazz_Tux,

I think number 2 is the correct one... unfortunately I can't test for 100% as I'm back home and out of 3G range again :(

With AT+COPS=0,2,"65501",2 it still connects via GPRS, however with AT+COPS=1,2,"65501",2 it refuses to connect and just gives me a steady red light.. I think this is what it should do if properlly put into "3g only" mode .. right ?

In fact once I had run it with AT+COPS=1,2,"65501",2 it would not connect at all anymore even when I attempted to redial... so I did a bit of experimentation and changed it to AT+COPS=1,2,"65501",0 and voila it connects again on GPRS...
 
Correct - The GPRS/3G setting is the number after the network - 65501 in this case. It would appear that certain cards prefer to have the network number rather than the network name.....I will look into this, since I have seen some phones (mobiles) pick up "Vodacom" and others "Vodacom-SA". For now, I am pondering changing the configs to use the network number rather....

Laterz !

Hrmmm, the Huawei E620 is an interesting beast.

Code: 
AT+COPS=?
+COPS: (2,"Vodacom - SA","VodaCom","65501",0),(1,"Vodacom - SA","VodaCom","65501",2),(3,"Cell C (Pty) Ltd","Cell C","65507",0),(3,"MTN (Pty) Ltd","MTN-SA","65510",0))
OK
AT+CSQ
+CSQ: 14,99

That makes me beleive UMTS is available, right? the last digit in the second sequence is 2.

As I pasted earlier, its pretty much impossible to tell this card to register as it doesn't like the last argument in the COPS command.

The light on the card is blinking green, which if my understanding serves me correctly, its registered to a GPRS network.

So ... I tried setting the required speed to 384...
Code: 
OK
AT+CGDCONT=1,"IP","internet","",1,1
OK
AT+CGEQMIN=1,4,64,384,64,384
OK
AT+CGEQREQ=1,4,64,384,64,384
OK
ATD*99***1#
CONNECT

Steady green light.

I'm stuck :rolleyes:
 
Maybe try:

AP+COPS=(1,"Vodacom - SA","VodaCom","65501",2)

:)

TOO MANY PARAMETERS

Anything with more than 3 arguments appears to bork out.

I've tried short, long and numeric operator specifications.

Also .... AT+CREG appears to support AT+CREG=2 in the spec. This should show something like 1,1,XXX,XXX,2 if you're registered to a UMTS network (and if my understanding of the spec is correct).

Appears the E620 doesn't support more than 2 arguments here either.

I must try the Linksys I got and see if gets a blue light, then at least we'll know its possible.
 
@sevenworth:

Thanks for the heads up on the Freedom toaster. I had already made a trip there and burned like a badger - even though it's perfectly legal to copy, I have been so indoctrinated by corporate software, that I felt a twinge of involuntary guilt..... But they don't have IPCop.
However, IPCop is only 50MB, so itwas a relatively painless download on 3G500.

@Tazz Tux: Thanks for your input. Got IPcop running on an old P3 box, and DHCP and setting up the wireless network was a breeze (don't worry about security, I've configured the Wireless Access Point to only accept known MAC addresses and I'm using 128bit WEP (only because one of the older machines can't do WPA) - and I hope that will keep most attackers out - so the network is ready for the hard part - getting the HSDPA card working when I get it back from Vodacom (it died during a flash upgrade and lost its EMEI (poor thing)).

So I'll be bugging you when I start that part of the project.

Hey guys, IPCop is very cool! Firewall, proxy server, port forwarding, traffic shaping, throttling, adserver blocking etc. and it's free! Maybe you can use it to unshape/reshape an ADSL line from Telkom!

Later...
 
New config for the e620 cards :(

Code: 
GPRS Only - AT^SYSCFG=13,1,3FFFFFFF,2,4
3G Only   - AT^SYSCFG=14,1,3FFFFFFF,2,4

<stab>
Certain people just can't stick to standards !! :D
</stab>

I'll try that, where ON EARTH did you get that from? will try it tomorrow when i'm in an area with damn reception ;)

Already had vodacom out here twice to find out why we 1Km away from the tower but have no reception whatsoever, appears they've not been able to find the problem

hehehe

Better to not ask such questions :D

The bigger problem is to make a std wvdial that will have those commands in...

Laterz !

Ok ... I won't ask such questions, I was actually thinking of VMWaring win xp and reverse engineering the vodacom dashboard to get the commands ... thank g0d I don't have to do it now ;)

The AT commands arn't a problem, the distribution we design uses etcnet which supports basically anything .... and ... I use it on my lappy. BTW, setting all this up actually prompted the rise of a bug which we submitted a patch for, so I'm very happy ;) We should have a site with all the config files on for all the distro's .... if you want I can targz the etcnet config and you can post it somewhere?
