请大神们赐教ENC28J60模块的问题

ENC28J60模块作为客户端，为什么不能获取局域网网页的内容；
ENC28J60模块能ping的通，自己电脑能打得开，却获取不到内容；

提示的很清楚，dns failed，解析服务器的ip地址错。
手工设置下试试。

我只是访问局域网里的web，应该不用设置DNS也可以访问的啊，为何response_callback没输出信息呢？

真的很高科技，还没玩过网卡这部分。 帮你出点搜主义，试试其他网页的内容，比如外网的？这样至少排除了，你网卡盾和程序的问题，如果外网也出不来那就找程序的问题呗？

如果网线接在路由器上（路由器可以连接外网），这样可以输出web内容的，但是我需要没有外网的情况下输出局域网web的内容，好像不行，不知道能不能解决呢

端口问题吧。可能在enc28j60上设置端口不是这样的。表追问，我不懂，猜的。可以自己去看下库。

这是因为<EtherCard.h>在以太网层，总是先向网关发数据，我的方法是内网服务器和网关设置成同一IP
