hi,

我使用EC200N, 识别设别、分配ip地址,ping这些都没问题。
但是当使用syn_ntp的时候经常会报错:

```
msh />ping baidu.com
ping: not found specified netif, using default netdev ec200x.
32 bytes from 110.242.68.66 icmp_seq=0 ttl=50 time=60 ms

msh />ntp_sync

```
更奇怪的是，我用socket tcp程序写了个简单的连接服务器的程序（这个程序在air724的模组上一切正常）
在ec200n上面，总提示
```
msh />tcp_client
[582593] E/at.skt.ec200x: 566 : Socket connect failed
[582599] D/at.skt.ec200x: ec200x device socket(0) connect failed, the socket was not be closed and now will connect retry

[582701] E/at.skt.ec200x: ec200x device socket(0) connect failed.
Failed to connect to server
```

请问这是咋回事，是EC200N的问题吗?

谢谢
