Missing configuration steps after Ping

Raspberry Pi Network HATs 3G/4G&LTE Base HAT

Hi Sixfab community,

I have the Telit ME910C1-WW with Base hat and I wanted to use it to connect my Raspberry Pi 4B+ to the internet. I ran through all the Sixfab tutorial documentation for setting up hardware, and then using the tutorial to configure ECM on my modem but once I got the last step it leaves off at a Ping test which technically is correct but my Pi could not resolve hostnames.

It took me 6 months of off & on troubleshooting but finally I resolved my issue of only being able to Ping IP addresses, but no hostnames. I wanted to share some additional steps to setup my Pi to browse the internet in case anyone else is stuck:

Following the troubleshooting steps at the bottom of the ECM tutorial, with a slight modication:

  1. FIRST, ensure the line ‘nameserver 8.8.8.8’ is in /etc/resolve.conf by running sudo cat /etc/resolve.conf
  • If not, run sudo nano /etc/resolve.conf add the line
  1. Then AFTER step 1, run sudo dhclient -v wwan0 and confirm you get an output message in shell saying “bound to {IP-Address} wwan0 -- renewal in 200216 seconds”
  • NOTE: The tutorial documentation reverses steps 1 & 2 which did not work for me
  1. Then run the AT command AT#ECM=1,0 activation line (I used minicom)
  • Should see OK returned
  1. Run ifconfig and note down the LTE modem’s IPv4 (interface wwan0)
  2. Edit the raspberry pi’s wlan0 network interface > IP Address
  • Assign a static IPv4 address to in the modem’s subnet (i.e 192.168.214.X/24)
  • Set the Subnet to 255.255.255.0
  • Set the Default Gateway to the modem’s IP (exact IP)
  • (Redundant but I did this too) Set the DNS nameserver to 8.8.8.8
  1. Internet should now be connected and hostnames can now be resolved.

I am definitely a beginner when it comes to networking and all, but I hope this can help someone pick up where the Sixfab tutorial ends and provide some steps in more detail. Thanks!
