After restart device the PPP connection is not established

Mon Sep 24, 2012 5:40 pm

Heloo!

After restart device the PPP (3G) connection is not established.

I have RB 411U f-v: 5.2 and inside 3G modem (mPCIE-E Option GTM 380).


After configuration PPP clients everything works correct. Connection is made.

My configuration PPP (before restart):
Code: Select all
[admin@MikroTik] /interface ppp-client> print
Flags: X - disabled, R - running 
 0  R name="era" max-mtu=1500 max-mru=1500 mrru=disabled port=usb2 data-channel=2 
      info-channel=2 apn="eradata" pin="" user="" password="" profile=default 
      phone="*99#" dial-command="ATDT" modem-init="" null-modem=no 
      dial-on-demand=no add-default-route=yes use-peer-dns=yes 
      keepalive-timeout=30 allow=pap,chap,mschap1,mschap2
My configuration ports (before restart):
Code: Select all
[admin@MikroTik] > port print
Flags: I - inactive 
 #   NAME                         CHANNELS USED-BY                      BAUD-RATE
 0   serial0                             1 Serial Console               auto     
 1   usb2                                3 PPP <era>                    9600


When I do restar device, the connection is not established.

the log shows me:
"initializing"
"waiting for packets..."
"terminating... - could not acquire serial port"
"disconnected"


My logs after restart:
Code: Select all

After Restart RB all settings PPP seems correct ( the same before restart), I can see the difference in the ports configuraftions.

What to do to get rid of the problem?
export-before-restart.txt
export-after-restart.txt

Please help Me.

Ha ha ha , leaved alone by Mikrotik? Ya, this is actual in 2016 year too: RB951G and E3276s 4G card - dances with drums - sometimes work sometimes no.
Old D-Link Dir-320 with custom firmware work with this card without problems. I still have perverted interest to Mikrotik because of price/posibilities...
After long researches I found Mikrotik hardware problem - not enough power on USB port. Problems was solved when powered USB hub was used...

Re: After restart device the PPP connection is not established

I was trying to connect a Huawei E3372 LTE modem. I used the mikrotik microusb to usb cable that came with the RB2011 router.

I can confirm this was a power issue. I was using RB2011 with a 5v 0.8a power.
Changed to 5v 1.2a power, still same issue.

Changed to a RB3011 with the 5v, 1.2a power - and plugged device straight into usb-a port instead of the usb micro port on the rb2011. - everything works as expected!
