Very slow internet on RAK7243

LPWAN Developer Gateways / Concentrators RAK7243
1

Hi,
Working with RAK7243 in the US and getting ~0.05Mpbs when trying to access the internet. Tried with Verizon and Webbing and got about the same.

and another question - I have the ppp0 up (in ifconfig) but no internet access.
I set in minicom to AT+COPS=0 and changed in the gateway-config to ‘Disable LTE automatic…’ and run ‘sudo pppd call gprs’. Please see below that command output -

Thanks

Hello, @sagis
You can try https://github.com/RAKWireless/quectel-CM-for-rpi .

Thanks @ZhuQI,
I installed it but no internet.

  1. How can I check that if it was connected ?
  2. What should be in ‘Configure LTE module’ In gateway-config ?
  3. ‘Configure APN Name’ in gateway-config ignored ?
    Thanks

Please make sure you have connected rak2013 and Raspberry Pi via usb cable.

Then, through the ifconfig command, you should see a network interface named wwan0.

Please select “Disable LTE Automatic Dial-up” in the sudo gateway-config command and restart the gateway.

Then, go to the directory /usr/local/rak/qmi and execute “sudo ./quectel-CM -s your_apn_name”. Under normal circumstances, you can connect to the internet.
