I have a Raspberry pi 3B+ with sixfab 4G Hat, I have a working connection to the internet via the simcard.
I wanted to make a hotspot, to attach a wifi camera to the pi.
Using this guide: Setting up a Raspberry Pi as an LTE Hotspot
But something is wrong because I cannot see my wifi that I setup. First I set it up as wwan0 instead of usb0 because I could not see any usb0 connected.
However despite no errors I don’t have any connection with another device and I seem to have lost the option to connect to my personal home wifi.
I figured wwan0 was not the right chose, so changed all conf files to usb0, but no succes, it says that
“interface usb0 does not exist!” when adding the bridge (‘sudo brctl addif bro usb0’)
But this time I still can connect to my home network, and have internet via 4G so at least this is working.
So instead of guessing another option, what could I check to determine the problem?
I double checked every letter, but despite making a typo in the question I used br0 and wwan0.But without succes. And when I redid today I succesfully setup a network (I can see it on my phone and pc) but without acces to internet. And the raspberry pi also has no acces to internet any more.
Which tools can I use to find the problem?
@JaTa Can you start over / re-image your SD card?
Also once you get your RPi booted, do sudo update && sudo upgrade -y
Once everything is updated, can you paste the output of ifconfig here so we can see what interfaces are showing up?
Thanks for the input Scott.
I executed the update en upgrade (sudo apt update && sudo apt upgrade) but one problem I have no internet on the pi currently so I will do a total start over. But in the mean time, this is the result of ifconfig:
Restarted everything, new version of raspberry pi 32-bit OS. New install of CORE, started the tutorial again. Stopped before creating the bridge because after reboot I don’t see the wifi.
Here is the output of ifconfig
@JaTa , I’m not sure what “CORE” is. This is what I would do: (I’m not saying it’s right or wrong)
Lets just get a baseline of a “clean” install with a properly working RPi
1/ Re-image the SD card with the RPi OS.
2/ Boot up, go through the regular setup things you do, (i.e. setup WiFi and localization etc. via Raspi-Config)
3/ Update/upgrade the OS.
4/ Ensure that both the LAN and WiFi connections are working on the RPi.
5/ Do NOT install any other software.
6/ Make sure your SixFab HAT is plugged into the RPi GPIO AND USB connection.
7/ The lets see the output of ifconfig.
NOTE: You may need to look around for a better tutorial on how to get just the RPi working on WiFi. once that is all working, then we can look at getting the SixFab stuff working.
Ok, sounds clear before the results of your test. I found a problem, my internet was down (My laptop was using the neighbours internet) so that’s solved. However I now see the network the pi creates so it seems that this is working. However I have no longer internet on the pi, so the cellular connection is somehow lost in the proces.
Core, as in sixfab core.This was installed to initiate the simcard and I thaught was necessary? When you start using the sim, you enable it in the webapplication (https://connect.sixfab.com/) and get the installation code: sudo bash -c "$(curl -sN https://install.connect.sixfab.com)" -- -t Aflutter-Untapped-Removing-Muzzle-Edgy-Passport isTrusted true
I ended this proces and start from scratch on a new SD card (Card 2) and here is the output after a clean install, and plugged in the sixfab hat (without any software or so, only configured the wifi which is working):
Thanks for the input. I searched online but only got fixes for very specific problems but nothing helped for the main problem. One of the things I cannot figure out is this: After a clean instal of raspberry pi os, setup wifi and connect the hat. lsusb shows the hat is correctly connected. However I cannot reach internet. My wifi says connected, my laptop is connected to the same internet and working fine. Turning it of and on again does not work (tested the wifi, rebooted, shutdown and start up).
I changed the conf file, nothing changed this is the config file:

this is the ifconfig result after changing the sysctl.conf:
Apologies for any inconvenience. After reviewing your messages above, it appears that you may be using a Telit module. Telit modules typically shows as the “wwan0” interface, whereas Quectel modules are recognized as “usb0” when Sixfab CORE is installed.
In light of this, it’s advisable to utilize the “wwan0” interface instead of “usb0” for your configuration.
I’ve also have reviewed our documentation to check any missing information to ensure a more seamless experience. The following note has been mentioned.
If you read my first question carefully you could have read that I tried wwan0 and usb0. Because at the time I didn’t know that a Telit modem should always use wwan0. So that is clarified but not the problem.
Using the ECM mode, I found out that this is quite tricky and just a pain to work with. The modem is quite stubborn to communicate with.
Link to a similar problem:
I went with libqmi-utils instead. Enabled network manager instead of dhcp, but still new errors keep popping up.
Using this guide I’m stuck at getting the operating-mode=‘online’ of the qmicli.
I tried these commands:
sudo qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode
sudo qmicli -d /dev/cdc-wdm0 --dms-set-operating-mode=‘online’
Error don’t have much info: (collection of errors after trying multiple times;)
Er: Warning ** Error reading from istream: Resource temporarily unavailable
error: operation failed: endpoint hangup
error: couldn’t release client: Transaction timed out
Er: error: couldn’t create client for the ‘dms’ service: CID allocation failed in the CTL client: Transaction timed out
Er: -Warning ** Error reading from istream: Resource temporarily unavailable
Er: error: couldn’t create client for the ‘dms’ service: CID allocation failed in the CTL client: Transaction timed out
Any help is welcome. I’m right now looking at seeing if the modem is receiving commands or something that could be interupting my commands.
