Zte mf287 disconnecting lte modem

Installing and Using OpenWrt
1

sorry for asking more assitance. I'm setting lte connection according to https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle:

opkg update
opkg install kmod-usb-net-qmi-wwan uqmi luci-proto-qmi kmod-usb-serial-qualcomm picocom

vi /etc/config/network

config interface 'wan'
option device '/dev/cdc-wdm0'
option proto 'qmi'
option pdptype 'ipv4'
option apn 'web'
option autoconnect '1'

reboot

Unfortunately it works for about 1 minute and than it disconnect and the command "ls -l /dev/cdc-wdm0" dont find any device. Any help? This is also the log:

The modem processor crashed. This is often caused by a lack of DC power. Is it an internal modem or a dongle/adapter plugged into a USB port?

3

thanks mk24, i replaced power supply and the internal modem is still disconnecting.

4

i tryed to reinstall from beginning but, the modem is still disconneting after 2/3 minutes. Any chance to get help? thanks in advance

5

I would flash back to stock and install all available upgrades. It is possible that an upgrade to the modem firmware fixes it.

6

unfortunatelly the stock firmware is gone since I get errors during openwrt flashing process:

cat /dev/ubi0_0 > /tmp/ubi0_0
cat /dev/ubi0_1 > /tmp/ubi0_1

There is any chance to get stock firmware somewhere?

7

ZTE doesn't provide official firmware updates, only via OTA. Sometimes full firmware packages can be found on the web.

As an alternative, you could try to fully reset the modem. I remember having modem problems on an MF287 Pro until I did that.
I don't have the steps for the MF287, only for the MF287 Pro, so YMMV. You will need to disable you WAN connection in the hope that the modem stays connected for a longer time:

  1. Install "adb" on OpenWrt
  2. Get a shell on the modem using "adb shell"
  3. Run one of the following reset commands (I'm unsure which one to pick, I didn't take notes on that):
zte_send_msg 6 # Factory-Reset Modem (restore USR Reboot)
zte_send_msg 1 # Factory-Reset Modem (restore USR)
zte_send_msg 2 # Factory-Reset Modem (restore FAB)
8

thanks andy,

I runed all these commands:
zte_send_msg 6 # Factory-Reset Modem (restore USR Reboot)
it didnt anyting

zte_send_msg 1 # Factory-Reset Modem (restore USR)
it rebooted the router after a while

zte_send_msg 2 # Factory-Reset Modem (restore FAB)
it rebooted the router after a while

I'll check if the reset is fixing the disconnecting issue. thanks for your help.

router keep disconnecting after few minutes.
I realized that in the status page (http://192.168.1.1/cgi-bin/luci/admin/status/overview) on the network area theere is a field : Expires: 0h 2m 45s. What does it mean? Is it related to the disconneting modem issue?

That's just the lifetime of the DHCP lease obtained from the modem. Does it still vanish from USB or does it "just" disconnect?

11

just checked, the countdown restart from 9minutes again, non disconnection related to this timer. There is any log to undestand why the modem is disconnecting? As far I can understand i can reconnect if I only reboot the router, because the "wan" interface in not present.

12

Please check again with logread, last time your modem disappeared ("USB disconnect").

13

after last manual reboot, no disconnection, nor in the log. I'll keep you updated about it. thank you very much for your help.

andy, one more question, which a good openwrt router model with following specs:
lte sim slot
4 giga ethernet ports
wifi

thanks again

15

I'm the wrong one to ask this, LTE is only my backup connection. I use a MF287 Pro for this purpose. I would create a separate thread in the Hardware questions and recommendations section.

16

I went for MF286R - well below my expectations.
The fact, that it is internally USB makes me feel like I've lost any advantage over just plugging LTE stick to any other USB-capable but better supported router.
I keep losing the connection probably because of incomplete configuration via front end.

17

it just disconneted. here are the logs.

I'm afraid, it crashed again.

I do have a "regular" MF287 like yours somewhere in the basement, I can check how stable mine is. But this will take a week or to.

ok! great... thanks for spending time to help me...
