我在无线路由器后面的局域网中有两台计算机。
一个有 ip 192.168.1.2 的 XP
这个有 W7 和 ip 192.168.1.7
如果我尝试从这台计算机 ping 另一台计算机，我会得到：
C:\Users\Srekel>ping 192.168.1.2
Pinging 192.168.1.2 with 32 bytes of data:
Reply from 192.168.1.7: Destination host unreachable.
Reply from 192.168.1.7: Destination host unreachable.
Reply from 192.168.1.7: Destination host unreachable.
Reply from 192.168.1.7: Destination host unreachable.
Ping statistics for 192.168.1.2:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Tracert 给出了相同的结果：
C:\Users\Srekel>tracert 192.168.1.2
Tracing route to 192.168.1.2 over a maximum of 30 hops
1 Kakburken4 [192.168.1.7] reports: Destination host unreachable.
Trace complete.
虽然我可以毫无问题地 ping 和跟踪路由器。我已禁用两台计算机上的防火墙。路由器设置为使用 DHCP（如果重要的话）。
这是“路线”的输出。

我已经建立并调试了一些网络，但我并不是真正的高级网络用户，所以我不确定可能出了什么问题。有任何想法吗？哦，从另一台计算机 ping 这台计算机也不起作用。
编辑：添加 arp 输出：
