4G/LTE Modem not connecting to the internet

hi, i sucessfully installed QMI on a TL-MR6400 V5.3 and it isnt connecting to the internet via 4G (i use swisscom) can someone give me settings for it?

You will also need to disable DHCP as advised on the device page.

okay it worked. now i only have a minor issue (isnt a problem) it doesnt show the internet connected icon even tho it is. its not showing signal strength either

search the forum for mr6400 led.

tried everything i could find. didnt work. the best i could do was show RSRP and set the LED manually. i could not get anything automatic
