OpenWrt support for Zyxel LTE5398-M904

[LTE5398]

Thank you @ncompact and @AndrewZ
You were right!
Somehow I missed the part that I have to configure the Quectel modem separately.

This is my latest configuration:

config interface '4G'
	option proto 'qmi'
	option device '/dev/cdc-wdm0'
	option apn 'web.vodafone.de'
	option auth 'none'
	option pdptype 'ipv4'
	option delay '30'
	option timeout '120'

For future reference, I am posting my command history for anyone else who might land here via a search engine

picocom /dev/ttyUSB3

Since I set the record straight, this is what my last log looks like.

Hello Guys,

i want to give an update on my issue with frequent disconnects and stability.
After the tests mentioned in this thread, the first thing i tried, was using modemmanager. i found that it reconnects automatically every 4h (maybe ip reset?) though the stability was greatly improved. My (cell locked) line never changed to 3g or to any other bts anymore. Also it always reconnected automatically really fast, so service monitor couldnt even recognize any downtime anymore.
for me modemmanager did the trick and got me a pretty stable and reliable connection.

The overall experience for me is now a lot better then before with stock rom or OpenWRT with qmi.

Thanks to all and special thanks to @ncompact for all the ideas

[ncompact]

hoping to do you a favor ...

I suggest you switch to ECM mode that was recommended to me by user @brada4

https://openwrt.org/docs/guide-user/network/wan/wwan/ethernetoverusb_cdc

---

if you're interested:

for AT commands use "picocom"
for sms management use "sms-tool"

uptime 10 days
no reconnection script needed,

2 connectivity failures detected during use but resolved autonomously by the router for about 2 minutes of no internet signal

if you want to detect all possible disconnections and you have a connection with unlimited gigabytes

GitHub - br101/pingcheck: Check connectivity of interfaces in OpenWRT

set AT command AT+QCFG="usbnet",1

+QCFG: "usbnet",1

edit /etc/config/network (only part of interest)

config interface 'wan'
        option proto 'dhcp'
        option modes 'all'
        option autoconnect '1'
        option device 'usb0'

ps: and reboot your router ... because if you don't do this you may detect a lack of connection ...

[brada4]

It depends on actual hardware and wiring, you must roll through all modes and measure which works best. One reconnects gsm with no updown to host ,another gives you perfect control over that aspect etc.

[eduperez]

@SeriousMt

i found that it reconnects automatically every 4h (maybe ip reset?)

Probably, that is your ISP.

[kostia]

Hi, if anyone need to restore to stock i followed this method:
prerequisites:
You must have Kernel2 stock image not erased

in openwrt do:
fw_setenv CheckBypass 0
mtd -r erase Kernel

Doing this, Bootloader will check the Kernel1 image, and will not pass the checksum
so this trigger the copy of Kernel2 to Kernel1

[MAVERICK255]

How to check kernel2 is not erased?

[ncompact]

hoping to help you (As for the question, I may have misunderstood it, in that case I apologize in advance) ...

if you have not done this step:

https://openwrt.org/toh/zyxel/lte5398-m904#copying_openwrt_to_the_recovery_partition

"Kernel2" has not been touched

show:

OpenWrt support for Zyxel LTE5398-M904

It only writes to mtd4/Kernel. Same as for NR7101, you may want to write to Kernel2 as well if you want to make sure the bootloader doesn't resurrect the OEM firmware.

if you want to go back to the original firmware you can do this:

OpenWrt support for Zyxel LTE5398-M904

Hi there, anyone knows how to revert to the stock firmware? The last avaiable snapshot is so awful and i'd like to be back on the original OS. I didn't find any kind of guide that explain how to do it...

what i did to install Openwrt:

Log in as “root” on 192.168.1.1 port 22
scp OpenWrt initramfs-recovery.bin image to 192.168.1.1:/tmp

Prepare bootloader config by running:

nvram setro uboot DebugFlag 0x1
nvram setro uboot CheckBypass 0
nvram commit

Run mtd_write -w write initramfs-recovery.bin Kernel and reboot

Wait for OpenWrt to boot and ssh to root@192.168.1.1

Sysupgrade to the OpenWrt sysupgrade image and reboot

I made a dump of the partitions before and after the migration on Openwrt and the md5sum of "Kernel2" remained unchanged since I did not touch this partition..

how to dump the current "Kernel2" partition and find its md5sum:

ssh to the router and then:

cat /proc/mtd

How to improve speeds on this router?

On ZTE MF289F i have 360Mb/s, but on this Zyxel 299Mb/s. Same ISP, same place.

[mkrle]

There is no solution for that yet. It looks like the problem is in the MT7621 USB3 driver affecting other platforms as well.

Zyxel NR7101 low performance

I haven't requested the source code for the NR7101. It's a MT7621 device with a Quectel modem. Didn't think there would be anything new in there. My best guess is that we're missing something related to ethernet <-> xhci in the MT7621 SoC. Maybe there's a more efficient way we can move buffers between those IP blocks? If there is, then that should affect any MT7621 device with a USB3 port.

[strips]

Thanks! This saved my ass I believe. Being on a working "vacation" and QMI was unstable. For every reboot I had no connection and had to change the APN between two known valid options and restart the interface to connect. Even then it only lastet hours before it went down.

I tried MBIM as well but it refused to connect.

Now I'm running ECM mode like described here:
https://openwrt.org/docs/guide-user/network/wan/wwan/ethernetoverusb_cdc

Now I got a connection after reboot. Just crossing my fingers it will stay connected of I will hear it from my wife and kids

[strips]

Update after a few days. ECM mode is stable but now I get an extra NAT in the picture. The USB-device always get an 192.168.225.0/24 address. I have an APN for public IP but that's no use now.

I would like to use QMI or MBIM.

[AndrewZ]

Then use it )
Switch the modem to MBIM and configure router as shown in the wiki:
https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle

[strips]

I did try MBIM but got connection refused every time. I might give it a new try in the weekend as my wife uses the wifi for work

[strips]

I'm trying to get MBIM to work again. I use the same APN as in QMI or ECM where it works. There is no PIN on the SIM.

config/network:

config interface 'wan_mbim'
	option proto 'mbim'
	option device '/dev/cdc-wdm0'
	option apn 'vpn.telia.no'
	option auth 'none'
