The problem is that the stick is still not supported in the option.c driver, not even in the latest kernels.

An easier way to get it working without rmmod and insmod is :

echo "19d2 0257" > /sys/bus/usb-serial/drivers/option1/new_id

Thanks LOM,

echo "19d2 0257" > /sys/bus/usb-serial/drivers/option1/new_id

Works beautifully!

Hi,

Does anyone have this LTE MF821 usb modem from telstra working with dd-wrt?

If so how do you have it configured? ie dial string, connection type, apn etc etc I've tried everything and no joy.

I've been through all the forum threads on it and I can't for the life of me work out why it doesn't work. I'm running DD-WRT v24-sp2 (04/15/13) giga - build 21286 on an Asus RT-AC66U.

I've worked out that when I plug it in, it connects in storage mode, so I found the command to fix that.

usb_modeswitch -v 0x19d2 -p 0x0166 -V 0x19d2 -P 0x0257 -M "55534243123456782400000080000685000000240000000000000000000000"

Which then shows the extra devices in

cat /proc/bus/usb/devices

and I get this in dmesg, which I think means it's working to some extent.

if I try this command

insmod usbserial vendor=0x19d2 product=0x0257

I just get:

insmod: cannot insert '/lib/modules/3.8.7/kernel/drivers/usb/serial/usbserial.ko': File exists

I tried the all the rmmod stuff below

rmmod option
rmmod usb_wwan
rmmod usbserial
rmmod sierra
insmod usbserial vendor=0x19d2 product=0x0257
insmod usb_wwan
insmod option


but it throws some errors and still no connection when I click connect in WAN status page:

root@DD-WRT:~# rmmod option
root@DD-WRT:~# rmmod usb_wwan
root@DD-WRT:~# rmmod usbserial
rmmod: usbserial: Resource temporarily unavailable
root@DD-WRT:~# rmmod sierra
root@DD-WRT:~# insmod usbserial vendor=0x19d2 product=0x0257
insmod: cannot insert '/lib/modules/3.8.7/kernel/drivers/usb/serial/usbserial.ko': File exists
root@DD-WRT:~# insmod usb_wwan
root@DD-WRT:~# insmod option

I still have my old Asus RT-N56U which is running the custom asus firmware (ie not supported by dd-wrt) and the usb modem works fine on that. So I know the modem definitely works.

Any assistance would be really appreciated as tearing my hair out with this now! Sad

Cheers

You shouldn't have to do a manual modeswitch, it should be done automatically when plugging in the dongle and 3G is selected in WAN setting.
If that doesn't happen then it may be due to a recently discovered and now fixed bug for the Broadcom platform.
Your other attempts to rmmod and insmod are just plain wrong and will not get the dongle working, the option driver has bound to the right interfaces so trying to load the crappy usbserial driver is only a step backwards, it is something we used a year ago when this dongle was not supported in the option driver.

pls give me the output for:

nvram show | grep 3gdata

Hi LOM,

Thanks for the reply, yeah I kind of assumed from all the threads I've read and their age that it was all done and dusted a while ago. But then wasn't sure as when I plug it in it connects in storage mode, so wondered if maybe it was still a manual workaround needed.

Anyway, I'll post output tonight as soon as I get home. Can you just clarify what you mean by WAN mode set to 3G please? I have the WAN set as follows:

Mobile Broadband
dial string *99#
apn telstra.internet
auto 4g/3g/2g

Do you mean the "auto 4g/3g/2g" needs to be set to force 3g or something?

I have tried all of the settings with no joy, modem still shows up in storage mode when it is first connected.

Cheers

OK so this is from a fresh install of ddwrt.

Setup as mobile broadband with force 3g and settings as per previous post. Plugged in modem and get following results. As you can see it just connects in storage mode only.

(Below these results are the results after issuing the modeswitch command)

What router and which dd-wrt build number?

19d2:0166 is the Windows install id before the dongle is getting mode switched into a modem.
This is obviously done for you since you got the GSM modem driver loading.

Show output from cat /proc/bus/usb/devices after the dongle has switched its mode and got a new usb id.
