![13.04 无法连接无线](https://linux22.com/image/968458/13.04%20%E6%97%A0%E6%B3%95%E8%BF%9E%E6%8E%A5%E6%97%A0%E7%BA%BF.png)
网络管理员可以看到我的家庭网络,并表示信号强度正常甚至很好,但就是无法连接。有时它会反复询问我的密码,但通常它只会尝试连接一会儿,然后给出“已断开连接 - 您现在处于离线状态”的消息。其他计算机连接没有问题,我的计算机连接到其他网络也没有问题。
我试过了:
- 关闭路由器并重新打开
- 关闭并重新打开计算机
- 删除连接信息,停止并重新启动网络管理器,然后重新输入信息,就像是新连接一样
- 删除连接,重启,重新添加
- 确保密码正确
- 切换“所有用户可用”和“自动连接”等设置
- 编辑:将以下行添加
blacklist acer_wmi
到文件 blacklist.conf 中,如下所示这个答案
...但这些都无济于事。
编辑2我目前无法通过以太网电缆访问我的路由器,因此route -n
目前无法通过命令行进行操作。我使用的 Mac 可以毫无问题地连接到互联网,因此请遵循以下已接受的答案https://stackoverflow.com/questions/6782658/how-to-get-default-gateway-in-mac-osx,我route -n get default
从 Mac 运行。这是否提供了所需的信息?输出是
$ route -n get default
route to: default
destination: default
mask: default
gateway: 192.168.1.1
interface: en1
flags: <UP,GATEWAY,DONE,STATIC,PRCLONING>

我已经使用这个网络几个月了,这个问题似乎每隔几周就会出现一次,每次持续几天,然后突然又开始工作,没有任何明显的原因。
一些可能相关的命令的输出:
输出iwconfig
