树莓派3安装最新的Raspbian,启动后在有上角网络链接处,不能搜索wifi热点。显示"No wireless interfaces found" 。然后通过“ifconfig -a”没有发现网卡,是不是判定WiFi和蓝牙已经损坏了?

月入3000的是反美的。收入3万是亲美的。收入30万是移民美国的。收入300万是取得绿卡后回国,教唆那些3000来反美的!

大师来看看,很长一段,现在截取的是有红色的地方。请问要关注什么参数?

openhab是一个开源的项目,打算玩玩,用的是他们做好的镜像,可以去百度了解一下。好像和Home Assistant有类似的地方

没有任何与WIFI相关的信息,这是不是就是说挂了?

看样子是没检测到mmc1设备,你试过用官方raspbian也是检测不到wifi吗?

是的,后来才换其他的镜像,网上也有人遇到wifi不能识别这个问题,反映应该是坏了的

WIFI 不能识别好像是通病,我有一批里出现了几个这样的问题,可能是芯片的缺陷。

我之前一批也有几个,用着用着没的,或是串口不通。。。 他这个东西不好查。日志是没看到的。 电路也不好查。另外一个显现是路由器比树莓派启动晚了。没有网卡。重启就可以。感觉不是那么靠谱。可以外接usb网卡吧
