板子接入sim卡網(wǎng)絡(luò)注冊(cè)和上下文激活已經(jīng)成功,從wap網(wǎng)關(guān)處也可以獲取ip了.

我從板子里ping百度的ip地址(115.239.211.112,115.239.210.27)是可以成功的,但是ping公司外網(wǎng)(180.168.27.58)死活不行呢.我從PC是可以ping通的,就是板子上不行.

老是返回ping: unknown host,理論上是不需要設(shè)置DNS了的,暫時(shí)也不需要域名...

目前板子射頻只支持2G網(wǎng)絡(luò),注冊(cè)時(shí)是UNINET.

這個(gè)會(huì)是什么情況呢?
