USB Broadband

B

balanga

I booted up Linux Debian on my ThinkPad T420 earlier, inserted a VodaFone USB Broadband stick, clicked on Broadband connection and it connected automatically, and a PPP connection was set up. I've never figured out how to do this on FreeBSD. I've spent many hours pouring over this but never figured it out. I know it's supposed to be straightforward, but I'm missing something.

Any step by step guide would be appreciated.
 
Well it sounds easy enough... but....

From what I can make out I just need to run ppp -ddial 3g where 3g is a section in /etc/ppp/ppp.conf
Code: 
3g:
  set device /dev/cuaU0
  set speed 921600
  set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
   \"\" AT OK-AT-OK \
   AT+CFUN=1 OK \
   AT+COPS=0 OK \
   AT+CGDCONT=1,\\\"IP\\\",\\\"www.plusgsm.pl\\\" OK \
   \dATDT\\T TIMEOUT 80 CONNECT"
  set logout "ABORT BUSY ABORT ERROR TIMEOUT 60 \"\" +++ATH O ATH OK"
  set phone *99\#
  set timeout 300
  set ifaddr 10.64.64.64/0 10.64.64.64/0 255.255.255.255 0.0.0.0
  add default HISADDR
  enable dns
  disable ipv6cp
as per Thread 61889

So I run ppp -ddial 3g and then see this from ifconfig:-
Code: 
tun0: flags=8050<POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500
   options=80000<LINKSTATE>
   nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
   groups: tun
   Opened by PID 1135
Seems like something is missing....

lsusb:-
Code: 
Bus /dev/usb Device /dev/ugen1.3: ID 12d1:1001 Huawei Technologies Co., Ltd. E161/E169/E620/E800 HSDPA Modem
The modem emits a blue flash every 5 seconds, although I don't know what this signifies.

Any comments appreciated.
 
Have you checked the logs to see what its doing?
/var/log/ppp.log

You may have to enable logging with this line in /etc/ppp/ppp.conf
Code: 
set log Phase Chat LCP IPCP CCP tun command

This is the /etc/ppp/ppp.conf that was used:-
Code:

 set log Phase Chat LCP IPCP CCP tun command
 set device /dev/cuaU0.0
 set speed 921600
 set timeout 0
 set authname wapuser1
 set authkey wap
 set dial "ABORT BUSY TIMEOUT 2 \

    AT+CFUN=1 OK-AT-OK \
    AT+CMEE=2 OK-AT-OK \
    AT+CSQ OK \
    AT+CGDCONT=1,\\\"IP\\\",\\\"internet\\\" OK \
    ATD*99# CONNECT"
 enable dns
 resolv writable
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.255 0.0.0.0
 add default HISADDR

Not sure about device or speed.

I did try this on TrueOS and it worked which is confusing...

This is your problem.

Try removing these lines(sims do not require auth)
Code: 
 set authname wapuser1
 set authkey wap

Also note in the thread you posted. My setup puts a timeout up top where you have zero.
https://forums.freebsd.org/threads/61889/#post-358754

There is also the possibility that your modem uses a different AT commands for connection.
Mine is Sierra based.
The Extended Command set is not official and varies from vendor. Huawei might be different.
 
When I run ppp a second time it uses tun1 and I don't know if the com port is still in use, so I have to reboot before a retest....

Also I get
Code: 
root@Test:~/ # ppp -ddial default

Is this an error?

Yes you need to reboot on each try. I see that even on mine. If I disconnect then reconnect it makes a new tunnel and fails.Needs to be tun0.
Probably need to destroy the old tunnel first at disconnect. Reboot does the trick.
