一个无法理解的微果投影仪 Wi-Fi 断连问题

    这是一个创建于 502 天前的主题,其中的信息可能已经有所发展或是发生改变。

    22 年 6 月京东入手一台微果 C1 ,在卧室投影看柯南和小新当背景音非常满意,期间有更新几个系统版本,出问题时检测为最新。 这是一台只能搜索到 2.4G 的设备,我用 K2P 放了一个 2.4G 只有投影仪使用,从入手到 12 月都正常在用,未发现连接问题。问题出在 12 月 28 号的时候,说来也巧,这天中招了开始请假,发现投影仪一直提示 xxx Wi-Fi 认证失败,反复连上几秒到几十秒就断开出现提示,然后我就去捣鼓了一下路由器,修改 SSID 名称密码、手动改信道、改加密逻辑、改为无密码认证、重置等,还是无法正常使用,然后尝试更换了路由器并执行以上操作,也依然如此。然后使用 iPhone 、一加放了热点,都还是不行。期间尝试了重置投影仪系统也是一样。 就这样搞了两天最后我笃定是投影仪坏了,因为人不舒服就躺了几天。申请了京东售后,京东很爽快的给我寄来一台新的,1 月 4 号收到,快快乐乐打开连接,不到 5 秒,立马就弹窗了,我人都麻了,不太理解这个情况,尝试联系坚果客服(是坚果的子品牌),说没有遇过这样的情况。 因为微果 C1 的系统无线能连上 ADB (非常良心),我判断系统可能也带有调试控制台,在点击系统版本后果然出现了一个 log 页面,在 log 页面开启日志后,在 Wi-Fi 反复断开的间隙中艰难的导出 log ,我截取了应该是触发了断开的 log 片段,有没有大佬能看明白为啥。

    试过路由器 WiFi 先隐藏 ssid ,然后换个 ssid 名字吗?

    看到 log 里有 Deauthentication ,搞不好是有人闲得无聊在搞断网攻击

    感觉是你附近有人一直在发 deauth, 导致 station 认为自己断网

    @ju5t4fun 试过隐藏,然后在投影仪直接添加,也会这样。
    Deauthentication 这个攻击是针对 2.4G 的吗?手机连接 2.4G 没有影响。

    很多人是闲得无聊拿 esp8266 之类的物联网模块做的,一般是只有 2.4G 的,因为便宜

    手机没问题的话可能是能防这种攻击,我之前试过路由器上跑 mdk3 模拟 SSID 来实现模拟定位,三星 S5 是能搜到这些 SSID ,定位也变了,但是小米 6 就搜不到。
