Hi,

Received another 4G modem from Swedish Bredbandsbolaget (BBB). A Huawei E3276 with the following respons:

Is there a way to add this ID manualy (sine there is already support on this modem, but with another ID)???

The Huawei 12d1:1f01 device is a direct ip ethernet adapter and some of these devices (under different Huawei E-numbers) could be switched into traditional serial ppp modems, some can not and your E3276 seems to be one of them.

dd-wrt is currently using a slightly modified modeswitch message in order to switch those devices which supports it into ppp modem mode so can you please try to do a manual modeswitch and give the cat output of the devices file after the stick has switched.
You'll first have to choose another WAN Connection Type than Mobile Broadband otherwise the automatic modeswitch will interfere with your manual, then
replug the modem and confirm with a cat of the devices file that it appears in default unswitched mode ie 12d1:1f01.

Then give the following command in a telnet session to the router:
usb_modeswitch -v 0x12d1 -p 0x1f01 -M 55534243123456780000000000000011062000000000000100000000000000

copy and paste the result in a post here.

Now, do it again (after replugging the modem) with this command:
usb_modeswitch -v 0x12d1 -p 0x1f01 -M 55534243123456780000000000000011062000000101000100000000000000

copy and paste that result here as well.
I suspect though that both of these commands will give the same result but it is worth testing anyway.

Hope this gives a clue. Anything else I can do to help? How are you doing adding support for the new ZTE MF821D ???

Thanks for testing, the first modeswitch message I gave you is what Huawei technicians told us a few years ago to use under linux, the second message is a very recent recommendation from them.
I had hoped that the second one would had switched your dongle into a slightly different mode but there is no difference.

12d1:14db needs the cdc_ether driver together with some rework of the dd-wrt WAN connection routines in the gui, it is on the todo list but I don't know when it will be done.

LOM, can you tell me what's status for E3276s-150 12d1:14fe? Is it currently usable? I'm thinking about switching to ddwrt on mr3020...

We are waiting for the huawei_cdc_ncm driver which is likely to be included in linux kernel 3.13 or 3.14.
It will not be possible to fit it or the other direct-ip/ethernet type drivers in the small flash of TP-Link Mobile routers, the 4MB is already filled up.
I'd suggest that you take a look at this OpenWRT fork:

http://ofmodemsandmen.com/index.html

it supports more modem protocols but has less of other features compared to dd-wrt.

Hi. Any progress on this subject? Will DD-WRT support Huawei NCM on WNDR3700? Thanks for great work.
