Hello, I have bought a SIMCom SIM7600G-H R2 mPCIe modem and I have configured correctly following the steps of the PDF https://support.industry.siemens.com/tf/ww/en/posts/how-to-use-mpcie-umts-lte-card/251844/?page=0&pageSize=10 I am using IOT2050_Example_Image_V1.1.1.img in the SD card. Technichal specifications of the modem: https://techship.com/products/simcom-sim7600g-h-r2-mpcie/ I have an IP in wwan0 interface and I can ping www.google.com when I have other interfaces (both Ethernet ports) disconnected. My problem is that the connection is very slow: I can't send a MQTT message to the Cloud broker or I can't upload a 1 KB file to the Cloud because it's appearing me a Deadline error of 60 seconds. I have the antenna installed and the gateway is placed in a office with a perfect coverage. I have installed a speedtest tool following https://lindevs.com/install-speedtest-cli-on-raspberry-pi/ and I get these bad results: 0,06 MB/s download and 0,06 MB/s upload. Then I have tried the same tool with wired ethenet connection and I get good results: 64,65 MB/s download and 91,90 MB/s upload. That's what is appearing in ifconfig command wwan0 part: And that's the result of mmcli -m 0 command: I have configured these on "sudo nmcli connection edit cellular-4g": set gsm.apn i.euskaltel.mobi set connection.autoconnect yes set connection.autoconnect-retries 0 save quit I think that some configuration will be wrong, because otherwise I don't understand this speed problems. Can someone help me? Thanks! Attachmentattachments.zip (302 Downloads) |
