描述
我使用 Panda Wireless PAU09 连接我家的无线网络。几个月前，连接开始频繁断开，大约每天一次（通常是在我离开电脑一段时间后 - 从未在我使用浏览器时发生过这种情况）。内核日志抱怨“帧大小错误”，并且每当我尝试在连接断开后重新连接时，我都会看到标准身份验证/拒绝关联舞动。通常我可以通过拔下适配器并重新插入并反复运行来使其重新连接systemctl restart network-manager，但这通常至少需要几分钟，并且已经成为一个彻头彻尾的头痛问题。有人对此有见解吗？

是的，我正在使用 Ubuntu 20.04...尝试修复 BSSID，nm-connection-editor幸运的是，日志现在显示相同的超时模式仅在一个频段上发生，我想这是一种改进。
退出暂停状态后，我得到了以下信息dmesg：
