I have two Routers, the 2nd a tp-link with dd-wrt. I configure it with the same SSID and other options to have one big wifi network. It worked well. But from one moment to another I was not getting internet.
At first I though I was being hacked. Then I found https://superuser.com/a/1145468/273358 And it turn out my ethernet cable was connected on a different port. Switched it, solve it.
EDIT: the strange IPs were: It was usually 192.168.100.1 for the 2nd router and 192.168.100.4 for my laptop.
But then I got
inet 169.254.83.125 netmask 0xffff0000 broadcast 169.254.255.255
And I made a ping:
ping 220.127.116.11 PING 18.104.22.168 (22.214.171.124): 56 data bytes 64 bytes from 169.254.83.125: icmp_seq=0 ttl=255 time=0.108 ms 64 bytes from 169.254.193.60: icmp_seq=0 ttl=255 time=92.558 ms

But I want to know what happened.
