I am new to this LTE stuff , so I am just learning all the commands and codes...
My router and modem seem to not want a good connection between them.
I have used putty to make the adjustmrnts as stated on some of the threads on here other have on here, and the first time I did that , I got my connection back,, working 100%
Example:
PUTTY:
echo 1199 9091 > /sys/bus/usb-serial/drivers/option1/new_id
picocom -b 115200 /dev/ttyUSB0
Then going into the AT commands below
at!entercnd="A710"
at!usbcomp=1,3,1009
at!reset
logged back into the router the next day, and I am back at the same issue.
I tried the above once more and , I am getting nowhere.
Putty comes back with "mismatched settings" when I re enter the above.
I have tried reseting the modem and router, also tried the simm card installed and removed
I do have access to the AT command line, so the modem is trying yo connect in some way.
If I am not connected to the modem, how is it, That I have a working AT command ? seems weird.
Below is my modem de-bug data

Update - all of this was due to a bad sim card not making contact correctly. When i used a friends sim out of her phone. I was able to connect to the modem with no issues.
