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>
recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtu expire
0 0 0 0 0 0 1500 0
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为
eth0 no wireless extensions
lo no wireless extensions
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=16 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
输出lspci为
