[网络连接] （已解决）我这个批处理是改网关的，但是碰到网卡名字改变的情况下改不了

@echo off
setlocal enabledelayedexpansion

REM 读取本机网关
for /f "tokens=3" %%a in ('"route print 0.0.0.0|findstr 0.0.0.0"') do (
    set gateway=%%a
)

echo 当前网关为：%gateway%

REM 获取网卡名称
for /f "delims=" %%a in ('netsh interface show interface^|more +3') do (
    set "str=%%a"
    for /f "tokens=*" %%b in ("!str:~46!") do set interfaceName=%%b
)

echo 网卡名称为: %interfaceName%

echo 输入数字1和2来选择网关，选1网关改成1，选2网关改成200 输入Q 退出

set /p "n=请输入选项: "

if /i "%n%"=="q" exit
if %n% equ 1 goto 1
if %n% equ 2 goto 2

echo 无效的选项，请重新输入。
pause
exit /b

:1
netsh interface IP Set Addr "%interfaceName%" Static 192.168.33.33 255.255.255.0 192.168.33.1 gwmetric=1
echo 网关已设置为 192.168.33.1
exit /b

:2
netsh interface IP Set Addr "%interfaceName%" Static 192.168.33.33 255.255.255.0 192.168.33.200 gwmetric=1
echo 网关已设置为 192.168.33.200
exit /b
