这日志大体是什么意思呢？是不是192.168.1.100不正常？？

检查192.168.1.100这台电脑的网卡MAC地址是否真的是00:22:FA:E5:7E:F4
检查192.168.1.100这台电脑的网线和网卡是否异常
不过这个IP是DHCP自动分配的 想找到恐怕不容易
一个局域网内电脑如果比较多 真好还是不要用DHCP服务
维护起来真的太麻烦

可以的，市面上都是108m的无线路由器了20m完全不在话下，108m代表无线速度中最高108mbps（约13.5mb/s）的传输速度，去除信号衰减也能达到50mbps+（约6.25mb/s）的速度，所以20m完全可以使用。另外市面上也有不少54m（约6.75mb/s）的无线路由器，比较早的了，去除信号衰减也可以达到30mbps（约3.75mb/s）左右的速度了。
