Hi there. I’m trying to establish connection to internet via 3g-modem and everything seems to be working, but connetion terminates every 3 minutes. No timeouts is specified. Same modem connected to PC works just fine.

PPP-Client config:
Flags: X - disabled, R - running
0 name=“Beeline 3g” max-mtu=1500 max-mru=1500 mrru=disabled port=usb3 data-channel=2 info-channel=1 apn=“internet.beeline.ru” pin=“” user=“beeline” password=“beeline” profile=default phone=“*99#” dial-command=“ATDT” modem-init=“” null-modem=no
dial-on-demand=no add-default-route=yes default-route-distance=1 use-peer-dns=yes keepalive-timeout=0 allow=“”

Here’s log:
10:13:30 async,ppp,info Beeline 3g: initializing modem…
10:13:31 async,ppp,info Beeline 3g: dialing out…
10:13:31 async,ppp,info Beeline 3g: authenticated

Can anyone help with this issue?

Try to add async,debug logging topic and check if there is some entry that might tell you when the modem was disconnected from the network.

That’s what I found:

Still, have no idea how to solve this. :frowning:

Hi,
Try set keepalive-timeout greater then zero.
Default value is 30 seconds, and it should be work with any operator in russia.

Sadly, keepalive timeout doesn’t change anything.
Interesting thing is, every time connection lasts exactly 2.57min.

Modem unlocked?

7

No manipulations with modem itself has made. Modem vendor and SIM are same - beeline.

8

Try to unlock it via firmware.
Some people says that modem this provider firmware and provider dial program sending some codes while dialing, so if you try to use another ppp-client you also need send some code or at-command, either provider terminate connection.

Problem solved through firmware updating. Truly, it was the ISP firmware problem. Thanks for advice.
