A more reliable ping error checking method:

@echo off
set "host=192.168.1.1"

ping -n 1 "%host%" | findstr /r /c:"[0-9] *ms"

if %errorlevel% == 0 (
    echo Success.
) else (
    echo FAILURE.
)

This works by checking whether a string such as 69 ms or 314ms is printed by ping.

(Translated versions of Windows may print 42 ms (with the space), hence we check for that.)

Reason:

Other proposals, such as matching time= or TTL are not as reliable, because pinging IPv6 addresses doesn't show TTL (at least not on my Windows 7 machine) and translated versions of Windows may show a translated version of the string time=. Also, not only may time= be translated, but sometimes it may be time< rather than time=, as in the case of time<1ms.
