I haven't seen that before.
Is it still grabbing the stats every minute (even though the results are null)?
I presume you haven't changed anything in any of the batch file(s).
Is Teststats2.BAT still generating Current stats O.K. (bit-loading etc.)?
Is the null data still showing in the modem's GUI O.K?
EDIT:
In getstats.BAT, curl should obtain this data & store it in a temporary file (gdata$$).
curl -s %URL% >> %WORKING_FOLDER%\data$$"
var DSLCfg = new Array(new stDsl("InternetGatewayDevice.WANDevice.1.WANDSLInterfaceConfig","Up","VDSL2","","6142","23367","0","0","6321","31180","66","98","0","0","62","121","G.992.3_Annex_K_PTM"),null);
var DSLStats = new Array(new stStats("InternetGatewayDevice.WANDevice.1.WANDSLInterfaceConfig.Stats.Showtime","5546","0","21115","0","1117","261","0","0","0","0","0","0"),null);
var DslUpTime = "231632";
var time = 1;
Then it is munged in temporary files TEMP & temp2 to get rid of commas & speech marks & add spaces etc.
You could try temporarily disabling the 3 temporary text files' deletion so that you view them in a text editor (& hopefully see where the null data starts) by adding rem in front of the relevant commands.
rem del %WORKING_FOLDER%\TEMP"
rem del %WORKING_FOLDER%\temp2"
rem del %WORKING_FOLDER%\data$$"
EDIT 2:
Just another thought.........
Getstats.BAT uses the modem’s IP address, the default being 192.168.1.1
From memory, didn’t you change the default address?
If so, is it possible that you need to re-edit this near the top of getstats.BAT:-
rem ********** Set the URL for obtaining the stats **********
set URL=http://192.168.1.1/html/status/xdslStatus.asp
The 2nd part of data grabbing in getstats.BAT uses xdslcmd info –stats
This part still seems to be working O.K.
..........& echo xdslcmd info --stats & echo ********5>CON & sleep 1 & echo exit & echo *********6>CON & sleep 1 & echo exit & echo **********7>CON & sleep 2 & echo ***********8>CON ) ^| Plink -telnet -P 23 192.168.1.1
The actual address is used here rather than %URL%:-
^| Plink -telnet -P 23 192.168.1.1 >> %WORKING_FOLDER%\data$$
