Hi, I have an RM500U-CNV, in a waveshare M2 to Ethernet adapter box. I am having trouble getting an internet connection out of it on Ubuntu 24.04.
I am getting a green light in the waveshare, which indicates it has a connection. The sim is unlocked and gets a good 5G connection in a phone.
I am using usbnet=3 as that seems to be the only one that allows the modem to connect (MBIM doesn’t give me a green light).
I see errors from network manager saying that the modem doesn’t support dual stack ipv4/ipv6. If I then disable ipv6, it says the modem doesn’t support ipv4. Other forums are suggesting this is because the (driver? firmware?) isn’t reporting the property IPSupportedFamilies. Sure enough there is IP line in mmcli -m 0:
You can see the firmware version in that mmcli response there. Is there a later version? Could I get the latest firmware and linux driver for RM500U-CNV? Is there a linux flasher for the firmware?
Thanks for the reply. I got your message with the latest firmware but I am not clear on how to load it from linux. What flash utility should I use?
Re ModemManager not fully supporting RM500U, what are you suggesting? Should I disable MM? I run the command AT+QNETDEVCTL=1,1,1 but what exactly does is that supposed to achieve? With MM disabled I don’t get a USB network connection at all. It does list a wired connection but if I connect a cable to the ethernet connection on the waveshare box I still don’t get any internet.
FYI, for anyone coming here with a similar problem. As I suspected, the Waveshare M2 to Ethernet box should have just worked out of the box. I eventually tried (very) long pressing the reset button (10+ seconds) on the box and sure enough everything just started working then. I think the modem card may have been a return and was already messed up when I got it.
By default it goes into router mode and runs its own little DHCP server. So no need for any messing around with AT commands at all! But at least I know more about that side of things than I did before I started Thanks to Bean for the support!
ModemManager will at least not send AT+QNETDEVCTL=1,1,1.
This module has many uses. For example, if you need to dial automatically when the computer is turned on and do not want to actively send AT commands, you can also configure it to set up datacall automatically.
hi, can i also request for the latest firmware for RM500UCNV, the firmware i have is still in 02 and im having issue connecting to the only SA network in my country, it was working perfectly before but it suddenly stop working ang cant search the network. im using windows and qnavigator to send AT command.
Hi, I don’t have any issues connecting to Smart and Globe. What puzzles me is why the DITO network (MCC-MNC 51566) doesn’t appear on the list when running COPS multiple times. It was working perfectly before and is the only true 5G standalone network in the Philippines. help me out please how to fix the issue.
