我感觉是电源管理(驱动?)的问题,是本子吗?我的Debian上网就有时抽风,以前为了降温用laptop工具自动管理电源时会出现这种问题。休眠后恢复也有时无法连wifi,重启网卡也无效只能重启。掉线时可以立即dmesg看看是否是驱动出错了啊

可以贴出问题时候最后一两百行 dmesg的log发上来 我最近也遇到类似问题 频繁断掉 好像是wpa_supplicant相关

我一个USB网卡,N300UM也一样的情况,
测试1连接后收发数据,最多两分钟断流,ping之类的都不通,ifconfig查看只有发包,没收到有数据包。
测试2连接后不收发数据,过10分钟再收发,通一两分钟后断流(情况同上)
测试3断流后不作什么工作,等一段时间(大概有20分钟吧),再收发数据,有时能,有时不能(没规律)。
测试4(在1或2断流后)重新挺拔后,回复正常一两分钟,然后重复。
测试5这USB网卡在win系(xp到7)都正常工作。
至此判断应该是内核驱动问题,没有测试其它驱动。
