GL-E750 OpenWRT官方源码编译概率性无网络

OpenWRT官方源码编译概率性无网络
1|使用官方源码编译默认配置+Luci；
2|编译固件刷机后网络概率性丢失；

刷机后有WiFi+网口无问题，重启后网口连接不上+无WiFi,等待一段时间20-30分钟后有1/3的概率恢复正常

你要给配置跟log，才有可能看是什么问题。

这是编译时配置，由于出问题时无法连接设备，未能记录到有效log；

另外这个设备有TTL接口吗？

OLED显示时间部分也发现一些问题，会显示00：00，log如下：

这个看起来麻烦了。ttl串口给了mcu了。应该是mcu程序跟固件没有对接好。
不是很乐观解决。

设备使用官方固件出现的无网络问题已经初步定位为5GWiFi部分的异常，拆除qca9887后故障未再复现；另外我还有两个问题，
1、GL-E750是否提供TTL口，主板上没有看到明显标识；
2、MCU部分禁用通电开机固件哪里可以获取到；（是否有提供这个固件，或者是否能公开MCU代码）

你这个log没看出哪里有异常呀！能否标示一下？

Hnmtc · 2021-11-02T11:54:49.364Z

log只有mcu异常部分；网络不可用的log未收集到，正准备通过ttl获取，拆机后没有看到ttl接口；（通过拆除硬件的方式发现，问题是出现在安装好qca9887模块的情况下，未安装此模块的情况下问题不会复现）

如果你手头上有硬件你可以复现一下问题；（刷openwrt官方附件，刷好后设置好网络，重启几次设备看看，很大概率问题会复现）

Hnmtc · 2021-11-02T17:55:14.447Z

问题已经初步解决，产生的原因与5 GHz 无线设备有关/ ath10K，不知何时能修复；
问题出现原因:修改了驱动程序默认值（国家/地区）；

ath10k_pci 0000:00:00.0: could not read board ext data addr (-145)

你的校准数据是怎么获取的？
你可以尝试使用ATH10K-CT看一下。
