Huawei E3276 4G modem

Wed Sep 04, 2013 6:42 pm

Hello!

I'm trying to get Huawei E3276 4G USB modem working with RB751U-2HnD (RouterOS 6.3, also tried with 6.2 and 5.24). This specific 4G modem is not listed as supported in the wiki, but unfortunately my mobile provider doesn't have any supported 3G or 4G devices to offer, so I decided to try anyway.

Short summary - the RB751 seems to recognize the modem just fine, but I cannot get connected to the internet. I think the problem is caused by some wrong settings in my ppp-out1 interface configuration (I've contacted my mobile provider for suggestions), but I'd like to verify I'm not missing anything on the Mikrotik side, because this is my first experience with Mikrotik.

I followed these wiki pages:
http://wiki.mikrotik.com/wiki/Option_Gl ... _USB_Modem
http://wiki.mikrotik.com/wiki/Huawei_EVDO

The port is detected correctly:
Code: Select all
 /port print
Flags: I - inactive
 #   NAME                        CHANNELS USED-BY                     BAUD-RATE
 0   usb1                               2                             9600
Modem responds to AT commands:
Code: Select all
 /system serial-terminal usb1 channel=0

[Ctrl-A is the prefix key]


ATI
^RSSI:12

Manufacturer: huawei
Model: E3276
Revision: 21.192.03.01.07
IMEI: 863781013170312
+GCAP: +CGSM,+DS,+ES

OK
So I set up the ppp-out1 interface with following configuration:
Code: Select all
/interface ppp-client print

Flags: X - disabled, R - running
 0    name="ppp-out1" max-mtu=1500 max-mru=1500 mrru=disabled port=usb1
      data-channel=0 info-channel=0 apn="internet.emt.ee" pin="" user=""
      password="" profile=default phone="*99#" dial-command="ATDT"
      modem-init="AT+CGDCONT=1,"IP","internet.emt.ee"" null-modem=no
      dial-on-demand=no add-default-route=yes default-route-distance=1
      use-peer-dns=yes keepalive-timeout=30 allow=pap,chap,mschap1,mschap2
The 'apn' and 'phone' settings are definitely correct. Modem-init is what I found on the web in many postings about using various Huawei modems (I also tried with empty modedm-init). I tried all possible combinations of data-channel and info-channel (4 combinations as my modem has 2 channels). I tried reducing max-mtu and max-mru to 512. PIN is empty because I disabled PIN verification in Windows' Mobile Broadband software (and verified I can get connected without being prompted for PIN).

With above settings, I can successfully get info:
Code: Select all
/interface ppp-client> info 0
       modem-status: ready
         pin-status: no password required
      functionality: full
       manufacturer: huawei
              model: E3276
           revision: 21.192.03.01.07
      serial-number: 863781013170312
   current-operator: EE EMT (cellid unknown)
  access-technology: Evolved 3G (LTE)
     signal-strengh: -89 dBm
   frame-error-rate: n/a
But when I try to connect with /interface ppp-client enable 0, the result is as follows:
Code: Select all
02:57:33 async,ppp,info ppp-out1: initializing...
02:57:33 system,info device changed by admin

02:59:31 async,ppp,debug ppp-out1: LCP down event in starting state
02:59:31 async,ppp,info ppp-out1: disconnected
Given the above, would you agree that the problem is in my ppp-out1 interface settings which I need to sort out with my mobile provider, or could it still be caused by incompatibility between my router and 4G modem or something I have missed in Mikrotik setup?

I consulted with my mobile service provider and found out what the problem is. The problem was not in my settings, but basic incompatibility between Mikrotik and Huawei E3276. Huawei E3276 works only in NDIS mode, but for RouterOS to be able to use a 3G/4G modem as ppp interface it has to work in RAS (dialup) mode. I returned the E2376 and obtained E3131, and voila - instant internet connection (not at 4G speeds, but for me this is not important).

Maybe these newer NDIS 4G modems will work as '/interface lte' type interfaces in the future, but at least with RouterOS 6.3 the E3276 was not recognized as such.

I guess realistically at this moment the only solution is to get a different modem. Huawei E3131 seems to be working fine for me.

would be nice to get Hilink / NDIS support for such devices.
With Openwrt and DD-WRT you will get them up ,...!

Thank you vatson. After I read this post I finally got my Huawei E3131 to work with 951G-2HnD.

I first disabled HiLink on the usb and turn it into a modem. I was using Windows 7 so it wasn't easy to make the stick to be recognised. I followed this post from ginggs:
http://mybroadband.co.za/vb/showthread. ... -%29/page2

I followed your steps but still I could not make it to work. Finally I upgraded the firmware of my Routerboard to 3.10 and the RouterOS 6.1 to 6.7, tweaked a little the configuration and suddenly something started to show on the logs. I needed to add another custom profile to the PPP settings to succesfully connect. I am conecting to a 3G network from Sweden by the name of TRE (http://www.tre.se).

Here are my settings, for other to use:
Code: Select all
/port print
Flags: I - inactive 
 #   NAME                                   CHANNELS USED-BY                                 BAUD-RATE
 0   usb1                                          3 PPP <ppp-out1>                          9600
Code: Select all
/interface ppp-client print
Flags: X - disabled, R - running 
 0  R name="ppp-out1" max-mtu=1500 max-mru=1500 mrru=disabled port=usb1 data-channel=0 info-channel=0 
      apn="bredband.tre.se" pin="" user="" password="" profile=3g phone="*99#" dial-command="ATDT" 
      modem-init="ATZ;AT+CGDCONT=1,"IP","bredband.tre.se"" null-modem=no dial-on-demand=no 
      add-default-route=no use-peer-dns=no keepalive-timeout=30 allow=chap
and here is the relevant profile:
Code: Select all
/ppp profile print 
Flags: * - default 
 0 * name="default" remote-ipv6-prefix-pool=none use-ipv6=yes use-mpls=default use-compression=default 
     use-vj-compression=default use-encryption=default only-one=default change-tcp-mss=yes 
     address-list="" 

 2   name="3g" remote-ipv6-prefix-pool=(unknown) use-ipv6=no use-mpls=no use-compression=no 
     use-vj-compression=no use-encryption=no only-one=default change-tcp-mss=yes address-list=""

I have the same LTE Stick (E3276 )
Any News about 4G and Microtik?

Thanks
