之前使用wpa_supplicant是可以认证成功的，但是过一段时间会掉线。。。

这个问题普遍是因为你的树莓派网卡MAC地址和IP地址没有设置正确。校园网内经过首次登录后会记录首次使用设备的网卡MAC地址，校园网为每个用户也分配了静态IP。所以请检查树莓派网卡的MAC地址是否已经克隆成你之前设备的网卡MAC地址，同时还要设置校园网分配的静态IP地址，通过 ifconfig 可以查看MAC和IP信息。

我只在这个树莓派上认证过，用mentohust和wpa_supplicant都是可以通过的，IP那些应该没有设置错吧。。。

这个拨号器主要是针对DrCom 5.2.1(X)版，建议你先用校园原版DrCom 5.2.1的拨号器测试拨号情况，mentohust和wpa_supplicant我没有使用过，我也不了解里面的协议是否与我这里面的一致。

解绑IP后重新连接，问题解决了。
