4G Signal Strength on MR6400

Hi @spamcop and all,

I installed curl and ran this command in your script. It seems like is not responding

root@OpenWrt:~# curl -v -d '{"module":"status", "action":"0"}' -H "Content-Type:
* Failed to connect to port 80 after 131855 ms: Error
curl: (28) Failed to connect to port 80 after 131855 ms: Error

ping is not responding either

My router is tp-link mr6400 and it's very similar to mr200

My version of curl is:

root@OpenWrt:~# curl -V
curl 8.8.0 (mipsel-openwrt-linux-gnu) libcurl/8.8.0 mbedTLS/3.6.0 nghttp2/1.62.1
Release-Date: 2024-05-22
Protocols: file ftp ftps http https ipfs ipns mqtt
Features: alt-svc HSTS HTTP2 HTTPS-proxy IPv6 Largefile SSL threadsafe UnixSockets

I appreciate any help here

and it's the IP of your LTE modem ?

My LTE IP address is

Tried this and the web server returned 404 :frowning:

root@OpenWrt:~# curl -v -d '{"module":"status", "action":"0"}' -H "Content-Type:
>  application/json"
> POST /cgi-bin/qcmap_web_cgi HTTP/1.1
> Host:

not similar enough, it seems.

Calling uqmi -s -d /dev/cdc-wdm0 --get-signal-info in a script that loops will crash the script if another process calls uqmi according to this:
