Signal level, Failed to get request

Hi all!

I have RUT955 with firmware version RUT9_R_00.07.06.16.
I scan the Modbus register of the Modbus router, which shows the signal level.
but I don’t get an answer for every request.
I tried to get signal level from CLI and also I don’t get an answer for every my command:

After this I tried two more routers RUT955 RUT9_R_00.07.06.16 - the same behavior!
Then I tried RUT906 07.10.2 and I didn`t get error: “Failed to get request. ERR: Failed to parse response”

What can this mean?
Thank you.

Hello,

Thank you for reaching out.

Based on the data you shared, the reported RSRP level of -112 indicates a very poor signal strength. This could significantly impact the router’s ability to maintain a stable connection and may also explain the intermittent responses to your commands.

Does your router currently have a stable internet connection, or are you experiencing frequent disconnections?

To improve signal quality and connectivity, I recommend reviewing and implementing the signal improvement suggestions provided here.

If the issue persists after improving signal strength, feel free to provide additional details for further troubleshooting.

Best regards,
