[gentoo-user] 4G Stick Huawei E3276

[Stefan G. Weichinger]

Greets!

I have a new and shiny Huawei E3276 stick here and want to test it with
my gentoo thinkpad running Gnome.

I managed to get some /dev/ttyUSB0 .. the device is usb_modeswitch-ed
automatically.

I also added the modules "option" and "cdc_ncm" to my kernel config and
the dmesg looks ok:

You're missing module 'qmi_wwan'.

Trying adding this to your kernel and replug the device (or use modprobe -v 
qmi_wwan).

PS.  I don't have such a device to test here, so hope this will get you in the 
right ball park.

Should I rmmod the others before?

I compiled and loaded that module ... no real difference to see ...
still no mobile broadband offered.

When I rmmod them all and plug in again, I get "option" loaded again.
Should I remove this one from my .config?

Even when I rmmod option, modprobe qmi_wwan and then plugin "option"
gets loaded (and no "mobile broadband" in NM).

Could it be related to our friend systemd which renames "wwan0" to
"wwp0s26u1u1i1" according to dmesg?

When you say no real difference ... dmesg should show that the module is 
loading.  /var/log/messages should show the same.

ifconfig should show a new device has been activated.

Yes?

I would get NM troubleshooted after the device is recognised by the kernel and 
the relevant modules are loaded.

I thought that this is a udev issue, rather than systemd.  I don't know 
anything about systemd (not tried it yet) and on a stable Gentoo install you 
should be able to see the wwan0 device in ifconfig.

PS. I should also say that I don't use NM on my machines ... so someone else 
should hopefully be able to help with NM issues.  I use symlinks in 
/etc/init.d/ for my NICs.

Sure, udev.

I get no wwan0 but this:

# ifconfig wwp0s26u1u2i1
wwp0s26u1u2i1: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 0c:5b:8f:27:9a:64  txqueuelen 1000  (Ethernet)

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Just read the posting by Diego Petteno on this issue:

NM sometimes is very comfortable on notebooks etc. ... so why not ...

I don't know if NM *should* detect that fuzzy interface-name now ...
maybe I should do some udev-rule to get wwan0 back? At least for a test.

If when you run ifconfig with no options you do not get wwan0 listed and NM 
likes the conventional device naming scheme, then I suggest you create a udev 
rule to achieve this and see if NM is happy thereafter.

I don't know about NM's preferences ... I just assume this could be
the problem.

Gotta dig up some udev-ruling for this, any quick pointers anyone?

even "easier":

You can change the device name using ifrename from package wireless_tools.

Now I have device wwan0 but still NM does not care about it.

I really don't want to rant ... but ... you know.

Just an observation:

Started a VM on my main workstation ... Windows XP inside of VMware Player.
Not even KVM or something ...

Connected that funny stick to that very VM ... and connected to funky
internet on first try ...

So what about that?

UNIX/Linux runs what percentage of the internet?

ok ok ...

LTE is new

linux has only a small percentage ...

gentoo even less.

I spent my whole afternoon trying to connect this very stick to the
internet ...

via 2 linuxes and 1 bsd .... not  ONE connection.

Right now I pull in an ISO at >1100kB/s, via that very stick, into an XP-VM.

(seems I don't have LTE coverage here ... but some UMTS or so )

-

Might be just plain ignorance by the provider. Not telling me access
infos etc.

My ADSL is slower.

*sigh*

Just a bit of feedback :-)

Don't you loooove OS automation?  Especially when it works!  ;-)

If you look at the device manager you will probably find different strings 
describing the USB device interfaces that WinXP detects/assigns compared to 
your Linux OS + udevd + systemd.

When you tried adding the new module you should see a load more interfaces 
coming up in dmesg, through usbserial_generic and then cdc_wdm and qmi_wann, 
like this:

  http://www.spinics.net/lists/linux-usb/msg64061.html

This guys seems to be getting 3 x ttyUSBX popping up.

Once you get to this stage with an appropriate udev rule if need be, then 
apparently you need to emerge this:

$ eix -l libqmi
* net-libs/libqmi
     Available versions:  
	~	1.0.0	[doc static-libs test]
	**	9999	[doc static-libs test]
     Homepage:            http://cgit.freedesktop.org/libqmi/
     Description:         QMI modem protocol helper library


and see if that with its qmicli utility allows you to manage your connection.

HTH.

I have my udev-rule to get wwan0 ... but I don't get that /dev/cdc-wdm
device :-(

This is rather frustrating ....

Re: [gentoo-user] 4G Stick Huawei E3276

[Stefan G. Weichinger]

next steps:

Pulled "HUAWEI Data Cards Linux Driver" from

http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDcwMzU=

With this I was able to enter the PIN and get "mobile broadband" in NM
... although still no connection.

The install-process of this driver-set is a bit problematic with gentoo
... some things don't fit too well and I assume that linux 3.8.4 doesn't
fit exactly as well.

But small progress, yes.

Are you sure it is an analogue modem?  Is this entry needed?

The driver should create a number of devices, ttyUSB0/ttyUSB1/ttyUSB2/...  Try 
them all in turn, only some may allow PPP connections.


> Baud = 9600

Unless you are just trying to dial out over a PSTN number (which you are not) 
you should be able to increase the baud to a higher number; e.g. 115200

Did you get anything more detailed in your logs?

Do you have a pap-secrets file even if empty?  If not:

touch /etc/ppp/pap-secrets; chmod 600 /etc/ppp/pap-secrets

If it still fails try adding something like this:

# Secrets for authentication using PAP
# client        server  secret                  IP addresses
"user"  *       ""


HOWEVER ... 

I thought that the whole idea is to use this modem to connect on a 4G (LTE) 
network ... yes?

In which case PPP is not the correct protocol.  If this Huawei is using 
Qualcomm chipset you should be using the qmi protocol and the cdc_ncm driver 
ought to do all the dialling using this device (from your dmesg):

[22765.769603] cdc_ncm 1-1.1:1.1 wwan0: register 'cdc_ncm' at
usb-0000:00:1a.0-1.1, Mobile Broadband Network Device, 0c:5b:8f:27:9a:64

Other driver/protocols that can achieve high speeds of 4G are cdc-ether, cdc-
acm, but your card ought to pick out the correct available protocol from the 
corresponding kernel module.  PPP incurs an overhead (due to packet 
encapsulation) and throughput speeds will be slower.

That's how I understand these devices to work, but unfortunately I can't 
verify any of this because I do not have access to such a device or a 4G 
network.  :-(

I hope someone else who does can chime in.

Yep, you are meant to see an ethernet interface coming up, which network 
manager will pick up and you should be able to configure and connect.  
However, you may need the latest drivers - have a look at this looong thread:

Found
and read that thread already today ... I will see how to get

Dunno. Removed. No difference.

Checked that before, only ttyUSB0 "speaks to me" as a modem.

This was detected by wvdialconf.

pap-secrets exists and contains the credentials I entered in
wvdial.conf (or was set via NM before maybe?).

So I am back on cdc_ncm now. And I removed all the stuff I installed
when testing that huawei-driver-package.

Rather hard to solve ...

phew.

Next small steps (but somehow promising):

I was able to connect via wvdial and pull an IPv4-IP-adress via dhcpcd ...

but the connection only lasted for maybe 10 seconds. Wrong parameters?

After that I have to re-plug the modem to get it working again.

This is with the modules coming with gentoo-sources-3.8.5 ... I assume
that the mentioned thread used older versions of this.

Gotta dig further.

Now time for a coffee!

Update:

It works. Although rather "un-polished":

I run wvdial ... it connects ... in a second terminal I pull an
IP-adress via dhcpcd and then started a ping to some remote IP immediately.

The wvdial-session then somehow loses connection to the modem or
something (I have to retry and provide the logs ... right now I am so
happy to have it working that I don't want to stop the connection  )
.... this mislead me all the times as I thought it lost connectivity.

But it still pings and works thereafter.

So it is somehow useable for me as an admin ... not so much for an end-user.

Contacted the dev from the thread ... he told me that the modules coming
with linux 3.8.5 should work just fine.

So it's more of a UI-issue right now ;-)

connectivity is good so far ...

phew!

Glad to hear to you got somewhere with this effort!  :-)

If you configure your /etc/conf.d/net for wwan0 (or whatever it is now called) 
to use dhcpcd you should not need to manually attempt getting an IP address:

  config_wwan0="dhcpc"

Don't forget to create a symlink for your interface in /etc/init.d/net.lo:

  cd /etc/init.d

  ln -s net.lo net.wwan0

  rc-update add net.wwan0 default

PS.  No idea if NM will barf with these settings, but this is the vanilla 
gentoo approach to network configuration and it will deal with the non-admin 
user problem.

Thanks for the reminder/suggestion ... for now it's enough to get it
working in the mentioned way as that stick is here for some weeks
only. It's only a a "test drive" and I have to return it if I don't
decide to do sign a contract (which is pretty expensive ...). I
research if we have good enough LTE-coverage at a customer's numerous
sites as we consider to back up their insufficient internet
connectivity somehow.

I would have to get it running with some router-distro like ipfire or
pfsense to be able to use it ... -> some more work ahead ;-)

Thanks, Stefan
