    Hey all

    I recently bought an RPI shield to use the pi as a router, I am having issues though. Mainly, I cannot make a connection even with a working sim inserted. I attempted the tip that is specified about using route add default ppp0, but i get the following error:
    SIOCADDRT: No such device

    Why can#t linux find my device? The LEDs are blinking regularly, and the device is setup on ttyUSB3, which is correct according to the documentation. I am running Raspbian Buster with nothing installed except for the things the default install.sh installs.

    thanks for your help!

    Hi.

    Which antenna are you using?
    Make sure your antenna is connected properly.
    +CSQ: 0,99^M indicates you have very weak signal strength.

    Have a nice day.

    Hi
    I’m using the full band LTE antennas that come with the 4G shield kit sold on sixfab. I get a regular connection on my phone. The antennas are plugged into the MAIN and DIV slots on the board. The output of pon says +CSQ: 16.99^M
