GL-XE300C4 multi network band/cell scanning

Hi folks,
I have tried searching for my enquiry but have not been able to find a definitive answer so am turning to the hive mind for assistance.

I am doing some validation testing for RF shielded enclosures and (without going into a long backstory) and using a methodology that with the XE300C4 and a connected device inside an enclosure, a scan for all available networks, bands and cells will be undertaken so show that no signals are able to be found.

However, I am running into difficulty with how to get a plain view of what is able to be found. I have been able to scan without issue but can someone spell out a very simple workflow (I am old and senile so it needs to be non technical) that would enable me to do 1 scan and find all networks that might be present. Currently I can only locate 1 network. However, I know that in my location multiple networks are present.

Part of my research leads me to think that one way might be to get an international SIM card that could/would allow multi mobile networks to be used. I don’t need to connect to any of the networks at all, I just need to be able to show that no networks are found while in the enclosure.

I’d really appreciate any help.

Hi @ph329ph
AT command AT+QSCAN can be used to scan for available network.

  1. log in to the ssh terminal as per SSH log in to the Router - GL.iNet Router Docs 4
  2. in the ssh terminal, enter the following command to search for available network
    gl_modem AT AT+QSCAN

Hi Cathy, thank you so much for getting back to me.
When I try to log in using that ssh command I receive the following message.

“Unable to negotiate with 192.168.8.1 port 22: no matching host key type found. Their offer: ssh-rsa”

I have tried a windows machine and also a Mac and get the same response.

Please try this on windows CMD:

ssh -oHostKeyAlgorithms=+ssh-rsa root@192.168.8.1

For macOS, please refer to the last section of the shared document—“Troubleshooting”:

So I am at another hurdle.

I have managed to successfully log in however when I use the command gl_modem AT AT+QSCAN the reply is ERROR

Please try using the following command to search the network (without band info):

gl_modem AT AT+COPS=?

Hi Will,
I’m really sorry but the AT+COPS=? command produces: +CME ERROR: 3

Please try rebooting the modem first, then run the network search commands:

gl_modem AT AT+CFUN=1,1
sleep 10
gl_modem AT AT+COPS=?

If the issue persists, could you please follow the guide and share your device with us via GoodCloud so we can check it remotely?

Kindly note to send us the MAC address and the router password via private message so we can access it
