开发板 无线网络 Android
您好，我于上个月采购了一块贵公司的OK4418C开发板，Wifi连网正常，用speedtest软件测试，速度可以高达50M(我司为100/40M宽频)，但因客户条件无法使用无线网路，在测试有线网路碰到相当的困难，因为个人初次接触Android开发板，经打转了好机个星期了，只好硬着头来请教，还望您不吝赐教。目前使用20190725的镜像，碰到的问题如下：1.开机后eth0的DHCP正常启动，ping区域网路与外部网路都ping的到，但lose都在30%以上2.浏览器无法连网(但改用Wifi测试时就正常)3.网线断开在重新插上后，eth0就无法连线了，ip也无法获取我司都是软体开发人员，但对于Android系统非常陌生，提出这些外行问题，让您见笑了，还望您多帮忙

- 您可以先用网线将开发板和电脑直接连接，看是否还会丢包。如果还有丢包现象，考虑网线问题或者开发板硬件问题。

感谢前辈回应。这两个星期所有网路硬体软体都有尝试过了，虽然Android的应用软件都经完成测试，但公司经过考量到我们自身开发能力不足，又欠缺资源的情况下，还是决定用原来的win7PE+PC。虽然成本较高，毕竟五六十台设备出货以后，后续的维护人力与公司信誉问题，价值应该超过这省下的十几万。
