Could anybody help to figure out what the problem is in the following batch code?
I want to check if the device with ip 192.168.0.1 is ready to connect.
I power off the device and power on it after executed the batch.
It seems the %errorlevel% is not working if first check is not 0

@echo off

set "host=192.168.0.1"

for /l %%i in (1,1,255) do (
    ping -n 1 "%host%" | findstr /r /c:"[0-9] *ms"
    if %errorlevel% == 0 (
        echo ping %host% ok.
        goto :endLoop
    ) else (
        echo ping %host% fail count %%i
        REM "ping -n 6 -w 1000 " sleep 5 seconds
        ping 127.0.0.1 -n 6 -w 1000 > nul
    )
)

:endLoop
echo Done

I got the following log, it can’t stop when ping response successfully.

^CTerminate batch job (Y/N)? Y

I tried the batch on windows 10 machine.
I expect the code can stop after ping response successfully.
