从12.10升级到13.04后的WiFi问题 – HP Envy dv6四核与rt2800pci
这在大约2天前升级后开始发生。
我有一台Verizon FIOS（无线）路由器……当我离开房间（大约20英尺远）时，我的无线连接断电……
我已粘贴下面的syslog输出。 底线是它断开连接然后不断弹出无线validation对话框，输入密码后无法连接，最后放弃了wifi连接。
我已经看到13.04升级报告了很多wifi问题…感谢您的帮助。
请注意，对于12.10，偶尔会发生这种情况（可能每周一次），但似乎与路由器的距离没有关联……我会重新启动以修复。 但随着13.04，它无法使用。

我在12.10遇到了这个问题，我解决了它删除Kwalletmanager并删除在Knetworkmanager上分配的无线配置，这样做后效果很好
