RM520N-GL no internet connection

IoT Modules 5G Module

I just received a waveshare 5G M.2 TO Gigabit ETH with a RM520N-GL module. Trying to get an internet connection which is failing. not sure what to do from here as i am new to this.

The device seems to be registered to the network, but no data transfer possible. i have set APNs. I have tried to manually attach GPRS with CGATT=1 but thats gives a error.

Firmware version RM520NGLAAR03A03M4G

[13:29:35.033]OUT AT+COPS?

[13:29:35.040]IN AT+COPS?
+COPS: 0,0,“Tele2”,2

OK

[13:29:43.579]OUT AT+CSQ

[13:29:43.584]IN AT+CSQ
+CSQ: 21,99

OK

[13:30:38.204]OUT AT+CGREG?

[13:30:38.209]IN AT+CGREG?
+CGREG: 1,2

OK

[13:30:50.436]OUT AT+CREG?
¡õ
[13:30:50.442]IN AT+CREG?
+CREG: 1,1

OK

Any help is appreciated, thank you

Hi,
For a data connection, you should use the QIACT command instead of CGATT.

Please try the following steps in order:

First, let’s check whether your modem is connected to the data network. You can use the CGATT command for this, but it’s important to follow these steps to ensure your modem is ready for 4G/5G data connection.

Make sure your APN settings are correct.

AT+QICSGP=1,1,“”
In the field, enter your internet service provider’s (Tele2) unique APN. For example, “internet” or “m2m.internet”.

Some operators may require a username and password. In this case, use the command as follows:

AT+QICSGP=1,1,“”,“”,“”

Use the QIACT command to enable the data connection.

AT+QIACT=1
The output of this command should be OK. If this command fails, double-check your APN settings or the activation of your SIM card.

Once the connection is established, you can check the IP address assigned to your module.

AT+QIACT?

You should see output like +QIACT: 1,1,1,“”. This indicates a successful data connection.

You can ping a server to test the internet connection.

AT+QPING=1,“8.8.8.8”
This command pings Google’s DNS server. If the connection is successful, you will see the ping results.

If you share the output you get from the steps above with me, we can resolve the issue more quickly.

Thank you so much. I can not find the QICSGP and QIACT commands in the manual.

I have added the APN (AT+QICSGP=1,1,“internet.tele2.se”), no username or password needed.

AT+QICSGP=1 returns +QICSGP: 1,“internet.tele2.se”,“”,“”,0.

But when i try to enable it with AT+QIACT=1 it returns ERROR (no cme code or so).

AT+QIACT? returns OK and AT+QIACT=? returns
+QIACT: (1-16)

i got it to work. in the end i had to use “internet” instead of “internet.tele2.se” thank you very much!
