    Default MDMA 1.1.0.1 Beta Testing (Huawei LTE Modems)

    MDMA 1.1.0.1 is released.

    This version adds support for the Huawei E3276 LTE modem which behaves very differently to previous modems.
    This particular modem has no RAS (modem) interface so a new command line option (/dialmode:ndisdup) has been added for connecting and disconnecting the network interface.
    The network interface has been available in other recent Huawei modems, but there have been reports that with some modems (e.g. E303) it just does not work, see here (edit: might only apply to Linux & Mac OS X). It seems the E303 responds with 'OK' to AT^NDISDUP commands, but does nothing. Fortunately, MDMA uses ^DIALMODE to determine if the modem is ^NDISDUP capable and the E303 reports that it is not.
    Some recent Huawei modems (K4605 / E372) also support the new AT^SYSINFOEX command for reporting the Radio Access Technology, this is used if available.

    This software is liable to blow up your modem, eat your data bundle and destroy your Windows partition, so please don't download:
    Download URL removed

    Regression testing is also needed for older Huawei modems.

    What's new in 1.1.0.1 beta 3 (2013/04/21):
    • Fix tab ordering, neaten display
    • Change default dial behaviour to use NDISDUP if available (based on response of AT^DIALMODE?) otherwise use RAS connection named 'MDMA', unless overridden by /dialmode command line switch

    What's new in 1.1.0.1 beta 2 (2013/04/14):
    • Huawei bands: group radio buttons, identify some LTE bands, refine logic for no bands selected
    • Add ^DIALMODE, ^CSNR, ^SYSINFOEX and ^SYSCFGEX capabilities to Device Info display
    • Display ^LTERSRP on main window

    What's new in 1.1.0.1 beta 1 (2013/04/02):
    • Detect Huawei E3276
    • Add /dialmode command line switch:
      RAS - pop up RAS menu (same as MDMA < 1.0.0.31)
      MDMA - use RAS connection named 'MDMA'
      NDISDUP - use AT^NDISDUP to dial and hang up (network connection)
    • Use AT^SYSCFGEX instead of AT^SYSCFG, if available
    • Use AT^SYSINFOEX instead of AT^SYSINFO, if available
    • Huawei LTE band configuration

    Some test results:
    ^CSNR ^NDISDUP ^SYSINFOEX ^SYSCFGEX ^DIALMODE
    Model Network Interface New RAT Info LTE band config
    E272 X X X X N/A
    EM770 X X X X N/A
    E303 (HiLink, after switching) X X X 0,2
    E1752 X X 2,0
    E1820 X X 2,2
    E367 X 2,0
    K4605 (E372) X 2,2
    E3276 (non-HiLink) 1,2

    Notes:
    • The E3276 does not seem to store the APN setting, so MDMA now sets the APN to 'internet' if it is empty on startup.
    • I have identified the LTE bands used by Cell-C and Vodacom, hopefully the other bands are correct too.
    • More info on LTE bands here.
    • The E3276 does not seem to report QoS values, not much I can do about that.
    • Switching from LTE to 3G/HSPA or from 3G/HSPA to LTE causes the connection to drop, I'm not sure if this is because of the modem or Cell-C's network. I am currently unable to test on Vodacom as my E3276/SIM card are not able to register on the Vodacom network in areas with LTE coverage.
    • USSD does not work on LTE, I'm also not sure if this is because of the modem or Cell-C's network.


    Using the modem's network interface (NDISDUP) while connected to a LAN
    By default, Windows assigned a metric of 10 to my LAN adapter and 25 to the modem's network interface. This means that internet traffic preferred to go via my LAN adapter unless I unplugged it.

    To access the internet via the modem's network interface and still access LAN resources via the LAN adapter, simply change the metric of the LAN adapter to 50 in the advanced TCP/IP properties of the adapter.


    Below is the output of 'route print' after changing the setting.
    Note 192.168.88.1 is the router on my LAN and 10.208.135.166 is the IP address assigned to my modem by Cell-C.

    Persistent Routes:
      None
    Connected but no throughput (NDIS connection)
    If you are connected using the modem's network interface but don't seem to getting any throughput, make sure that the TCP/IP properties for the adapter are configured to 'obtain an IP address automatically' and 'obtain DNS server address automatically'.
    You can check by typing 'IPCONFIG /ALL' at the command prompt and making sure the adapter does not have a 169.254.x.x address and that the DNS servers' IP addresses are sane. This seems to be an issue with Windows 8. (Thanks morkhans)


    Unbind unnecessary services from the NDIS interface
    By default, Windows binds Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks to all network interfaces. You do not not want these on your public interface. Unbind them and probably everything else except for TCP/IPv4.


    Explanation of ^DIALMODE
    AT^DIALMODE? queries the dial-up modes available on the modem.

    Defined values of the first parameter <value1>:
    0: Modem mode
    1: NDIS mode
    2: Modem mode and NDIS mode

    Defined values of the second parameter <cdc_mode>:
    0 (or not present): Modem and NDIS modes do not support CDC specification
    1: only Modem mode supports CDC specification
    2: only NDIS mode supports CDC specification
    3: both Modem and NDIS modes support CDC specification

    I'm hoping that in future MDMA can use AT^DIALMODE? to determine whether to use NDIS dialling or fallback to RAS dialling.

    What is ^LTERSRP?
    When connected on LTE, the E3276 periodically reports a pair of values e.g.
    ^LTERSRP: -100,-7
    I think these are the RSRP (Reference Signal Received Power) in dBm and the RSRQ (Reference Signal Received Quality) in dB. See here and here.

    Here is how to do it:
    1. In MDMA select "Device Info", make note of "PC UI Port" number.
    2. Open Hyper Terminal, use this number and default Windows speed settings.
    3. Press AT [ENTER], you should see response OK.
    4. If you can't see what you are typing, type ATE1 [ENTER]
    5. Now query modem with the following:
    ^NDISDUP?
    ^NDISDUP=?
    ^SYSINFOEX?
    ^SYSINFOEX=?
    ^CSNR?
    ^CSNR=?
    ^DIALMODE?

    6. Copy/paste, or capture entire session.

    Example of E367

    Code:
    at
    OK
    at^dialmode?
    ^DIALMODE:2,0
    
    OK
    at^dialmode=?
    ^DIALMODE:(2-0)
    
    OK
    
    at^csnr?
    ^CSNR:-80,-7
    
    at^csnr=?
    ^CSNR:(-145--60),(-32-0)
    
    OK

    Does the same happen with MDMA 1.1.0.0?
