Thanks. I'm trying to diagnose non bufferbloat related ping having increased from circa 35ms to circa 60ms when unloaded. Any idea? Cell tower maintenance? Signal stats excellent and same cell tower.
root@OpenWrt:~# mmcli -m any --signal-get
----------------------
Signal | refresh rate: 5 seconds
----------------------
LTE | rssi: -44.00 dBm
| rsrq: -7.00 dB
| rsrp: -72.00 dBm
| s/n: 19.60 dB
But this ping increase only affects the Zyxel NR7101 and not my Pixel 3a.
Nob, and trying to do this. HAve a Telenor like you.
Got the CP2102, and it works.
But do you breake the boot, or do you need to get the root psw for shell session?
thanks!
These are the high level steps I used to get back to stock FW:
Get a USB Serial adapter and connect to the on-board connector.
Connect with a terminal application as the device boots up. This will give you a shell session on the device, but without using the network.
Temporarily enable http/https/ssh connectivity (iptables). This will open the device to allow you to connect to it through its internal Wifi AP.
Why do you gents want to go back to original firmware?
I have found 22.03.2 to work extremely well with this device, which has been running for months now with great LTE stats and without any issues whatsoever.
The only caveat was that to keep the device connected following ISP disconnects I had to upgrade ModemManager to version 1.18.12 (by manually installing .ipk) and edit the 10-report-down script to:
BTW any disadvantage to editing the /etc/init.d/modemmanager service file to replace 'INFO' with 'DEBUG' and run ModemManager permanently in debug mode to enable sending such AT commands now and then? Or better not to run with 'DEBUG' when not strictly needed?
Is there an 'ondemand' equivalent for this device?
root@OpenWrt:~# cat /etc/rc.local
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
echo "ondemand" > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
exit 0
root@OpenWrt:~# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
cat: can't open '/sys/devices/system/cpu/cpufreq/policy0/scaling_governor': No such file or directory
