Internal USB Broadband modem

Hello.

I would like to be able to go online using the internal USB broadband modem in my laptop. So far I have gathered the following:

Code: 
$ dmesg | grep -i broadband
cdce0: <Dell Wireless 5530 HSPA Mobile Broadband Minicard NetworkAdapter> on usbus3

$ dmesg | grep -i ue0
ue0: <USB Ethernet> on cdce0
ue0: Ethernet address: 02 : 80 : 37 : ec : 02 : 00

$ usbconfig
ugen3.2: <Dell Wireless 5530 HSPA Mobile Broadband Minicard Device Dell> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
I have looked into ppp(8), and I have tried the following:

Code: 
$ ppp
set device /dev/ugen3.2
term
AT
Warning: at: Invalid command
Warning: at: Failed 1
I have a PIN code for my SIM-card, but the AT-command set doesn't seem to work.

Is this card even supported?
 
ugen(4) is just a generic USB device driver. You'll need a specific driver for the hardware.

You might give u3g(4) a try, no idea if it works for this card but it's worth a shot.
 
Thank you for your reply!

I tried loading u3g in /boot/loader.conf, but upon booting it didn't appear in the output from dmesg. Perhaps my card simply isn't supported.
 
I can't get any further with this one, so I'm wondering if there is a list
of supported external USB adapters somewhere?
 
I found the following in /sys/dev/usb/serial/u3g.c, so it appears that 5530 isn't among the supported Dell cards:

Code: 
static const struct usb_device_id u3g_devs[] = {
#define	U3G_DEV(v,p,i) { USB_VPI(USB_VENDOR_##v, USB_PRODUCT_##v##_##p, i) }
	U3G_DEV(DELL, U5500, 0),
	U3G_DEV(DELL, U5505, 0),
	U3G_DEV(DELL, U5510, 0),
	U3G_DEV(DELL, U5520, 0),
	U3G_DEV(DELL, U5520_2, 0),
	U3G_DEV(DELL, U5520_3, 0),
	U3G_DEV(DELL, U5700, 0),
	U3G_DEV(DELL, U5700_2, 0),
	U3G_DEV(DELL, U5700_3, 0),
	U3G_DEV(DELL, U5700_4, 0),
	U3G_DEV(DELL, U5720, 0),
	U3G_DEV(DELL, U5720_2, 0),
	U3G_DEV(DELL, U5730, 0),
	U3G_DEV(DELL, U5730_2, 0),
	U3G_DEV(DELL, U5730_3, 0),
	U3G_DEV(DELL, U740, 0)
        ...
#undef	U3G_DEV
};

I will look into one of the Huawei ones. Thank you for all the advice!
 
I finally managed to get this working. Here's how:

1) Add
Code: 
umodem_load = "YES"
to /boot/loader.conf
This should create /dev/cuaU0 (USB to serial device).

2) Verify that you can talk to the modem using the ppp-command:
Code: 
# ppp
ppp> set device /dev/cuaU0
ppp> set speed 38400
ppp> set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.255 0.0.0.0
ppp> add default HISADDR
ppp> term
AT+CFUN=1                    /* Enable RF - this will only work if you disable WLAN by pressing e.g. FN+F9 (Dell) */
AT+CGDCONT=1,"IP","internet" /* This is an ISP-specific Access Point Name (APN) - Google is your friend */
ATD*99#                      /* Dial */

If your connection attempt is successful, your prompt should change from ppp to PPP. If it stops at e.g. PPp, here's a good reference: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ppp-troubleshoot.html

If your SIM-card requires a PIN-code, you can provide this using AT+CPIN="1234".

Some service providers will require that you provide a username and password with [cmd=]set authname <username>[/cmd] and [cmd=]set authkey <password>[/cmd].

It might be useful to keep [cmd=]tail -f /var/log/ppp.log[/cmd] running when troubleshooting.

Good luck!
 
Greetings to all!

I have a problem similar as your, talin:
I would like to be able to go online using the internal USB broadband modem in my laptop. So far I have gathered the following:

My serial device appears after loading the module umodem. But the problem is not solved. Please help me make the right ppp.conf. I have used this /etc/ppp/ppp.conf:

Code: 
default:
 set log Phase Chat LCP IPCP CCP tun command
 ident user-ppp VERSION (built COMPILATIONDATE)
 enable dns
 set speed 115200
 set timeout 180
beeline:
 set device /dev/ttyU0
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT+CGDCONT=1,\"IP\",\"internet.beeline.ru\" OK ATDT\\T TIMEOUT 60 CONNECT"
 set phone "*99***1#"
 set login

 set authkey "beeline"
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.255 0.0.0.0

Your modem does not like something about this. You can try just removing it, together with its ok messages. It would help if you learn about chat script syntax. Try this for a dial line:
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATDT\\T TIMEOUT 60 CONNECT"

I think that is all I needed when connecting a device last time I tried.

Its probably the 'wrong' format, check mine:
Code: 
AT+CGDCONT=1,\\\"IP\\\",\\\"www.plusgsm.pl\\\" OK

Try this:
Code: 
AT+CGDCONT=1,\\\"IP\\\",\\\"internet.beeline.ru\\\" OK
