Constantly Loosing Cellular Connection on Spitz x3000

Technical Support for Routers 4G LTE, 5G NR, USB modems

To expand a little bit more:

I’m using a Mac to connect to my Spitz x3000.
When I used these two versions, I still had disconnection issues:

RM520NGLAAR01A08M4G_01.200.01.200
RM520NGLAAR03A03M4G_01.200.01.200
  1. I opted for newest version RM520NGLAAR01A08M4G_01.202.01.202, released in February 2024, which is available in the original repository here
  2. After downloading this zip file, I copied it to my router like so:
FILE=RM520NGLAAR01A08M4G_01.202.01.202
scp -O ~/Downloads/$FILE.zip root@192.168.8.1:/$FILE.zip
  1. I ssh into my router and run the upgrade commands (like mentioned in this guide here):
ssh root@192.168.8.1
FILE=RM520NGLAAR01A08M4G_01.202.01.202
unzip /$FILE.zip -d /$FILE
cd /usr/bin/ && wget https://fw.gl-inet.com/tools/quectel_tool/QFirehose-mtk7981a-sha256-c0b944
chmod 775 QFirehose-mtk7981a-sha256-c0b944 && sha256sum QFirehose-mtk7981a-sha256-c0b944
QFirehose-mtk7981a-sha256-c0b944 -f /$FILE
echo 1 > /sys/devices/platform/11280000.pcie/pci0001:00/0001:00:00.0/0001:01:00.0/remove
echo 1 > /sys/devices/platform/11280000.pcie/pci0001:00/0001:00:00.0/rescan
gl_modem AT AT+QGMR
rm /$FILE* -rf

I haven’t yet run into disconnect issues with this latest firmware version, but if I still face those issues, I will report back with more information.
