看坛子里都说wifi模块不稳定,容易掉线或崩掉。我把我测试过的发出来,希望大家测试过的跟帖
RTL8723BS 连续ping 10小时,无异常
离线
那我连续传数据试试。奔溃后rmmod,重新insmod行不行
离线
我用zero测试过在线听歌,没注意多长时间,会出错
用的什么模块
离线
用的RTL8723BS模块,但是出错后不影响在线听歌。
什么错,出错后通信没问题?
离线
连续ping正常,但大量传输数据,过一段时间会崩溃,时间没规律,有时10分钟出错,有时20分钟,崩溃后禁用网卡不行,必须重启,我是用udp包方式传数据,传输速率大约140Kb/s
可以把信号强度打印出来,会不会发热导致信号强度衰减
离线
可能不是zero对wifi的干扰,2.4G频段本来就环境干扰多。UDP协议是不可靠传输。我觉得你在zero的测试是正常的
但是同样的模块,比如8723bs,在zero正常,在nano崩溃,就奇怪了,两边的驱动是完全一样的吗?
离线
对比一下驱动,或者发一份上来我也对比一下

RTL8188CUS不一会就崩了
