Batch file for Windows - problem with goto

Question

I'm writing a Windows batch file which starts an executable file depending on the status of the wifi connection, and a user choice.

The script uses an infinite loop with a for.

echo off
SETLOCAL EnableDelayedExpansion
timeout /t 300
for /l %%n in (1,0,10) do (
    netsh wlan connect ssid="xxxx" name="xxxx"
    if errorlevel 1 (
        echo error
    )
    choice /c sna /d n /t 30 /m "Text"
    if errorlevel 3 (
        echo Choice A
        exit
    ) else if errorlevel 2 (
        echo choiche N
    ) else if errorlevel 1 (
        echo choiche S
    ) else if errorlevel 0 (
        echo Default
        exit
    )
)

After the first if, that checks the connection is established, I would like to insert a goto to skip the choice part and go directly to the end of the loop and restart the iteration.

I tried to put a simple goto end and label :end but the batch doesn't work properly.

echo off
SETLOCAL EnableDelayedExpansion
timeout /t 300
for /l %%n in (1,0,10) do (
    netsh wlan connect ssid="xxxx" name="xxxx"
    if errorlevel 1 (
        echo error
        goto end   <<<<-----------------------
    )
    choice /c sna /d n /t 30 /m "Text"
    if errorlevel 3 (
        echo Choice A
        exit
    ) else if errorlevel 2 (
        echo choiche N
    ) else if errorlevel 1 (
        echo choiche S
    ) else if errorlevel 0 (
        echo Default
        exit
    )
    :end
)

I don't know if it's a matter of environment variables or something else.

What about using conditionals, e.g. && (echo success) || echo fail, for the first command. This has the effect of reversing your initial if/else structure, and thus removes the need for a goto.

@Echo Off
SetLocal EnableExtensions
%SystemRoot%\System32\timeout.exe /T 300
For /L %%G In (1,0,10) Do (
    %SystemRoot%\System32\netsh.exe WLAN Connect SSID="xxxx" Name="xxxx" && (
        %SystemRoot%\System32\choice.exe /C sna /D n /T 30 /M "Text"
        If ErrorLevel 3 (
            Echo Choice A
        )
        If Errorlevel 2 (
            Echo Choice N
        )
        If ErrorLevel 1 (
            Echo Choice S
        )
    ) || (
        Echo Error
    )
)

This is just a simple IF-THEN-ELSE, isn't it?

echo off
SETLOCAL EnableDelayedExpansion
timeout /t 300
for /l %%n in (1,0,10) do (
    netsh wlan connect ssid="xxxx" name="xxxx"
    if errorlevel 1 (
        echo error
    ) else (
       choice /c sna /d n /t 30 /m "Text"
       if errorlevel 3 (
           echo Choice A
           exit
       ) else if errorlevel 2 (
           echo choiche N
       ) else if errorlevel 1 (
           echo choiche S
       ) else if errorlevel 0 (
           echo Default
           exit
       )
   )
)

If the netsh command gives an errorlevel geq 1 you want to show an error, ELSE you want to ask the user...
