Hello,
I am currently working with the RG255C 5G RedCap module, and I’m exploring the ECM mode with the AT+QCFG=“usbnet”,1 command. Then i define my PDP context using the AT+CGDCONT=1,“IP”,“my_apn” command. The registration to network is OK :
AT+CEREG?
+CEREG: 0,1
AT+COPS?
+COPS: 0,0,“Orange F”,7
AT+QCSQ
+QCSQ: “LTE”,-72,-100,12,-8
I got an IP with: udhcpc -i usb0
, but my ping to 8.8.8.8 is not working
It’s possible that I might have missed out on certain essential steps to ensure a connection in ECM mode.
Thanks,
silvia

Dear @hmaied
Please check the response of route -n and check the default route.
Hello,
I am facing a similar Issue. I have the RG255C-GL in ECM Mode and cannot ping from the linux device (Raspberry pi)
AT+CEREG?
+CEREG: 0,1
AT+COPS?
+COPS: 0,0,“o2 - de”,7
AT+QPING=1,“8.8.8.8”
+QPING: 0,“8.8.8.8”,32,53,255
+QPING: 0,“8.8.8.8”,32,36,255
+QPING: 0,“8.8.8.8”,32,36,255
+QPING: 0,“8.8.8.8”,32,37,255
+QPING: 0,4,4,0,36,53,40
So from my point of view, the modem is connecting and working. However from the pi I am not able to to send any data through the modem.
ip r:
default via 192.168.224.1 dev usb0
192.168.224.0/22 dev usb0 proto kernel scope link src 192.168.226.62
ping 192.168.224.1
works
ping 8.8.8.8
does not
Any ideas?
You need set
AT+QMAPWAC=1
It takes effect after reboot.
