It is very confused that I cannot connect the hokuyo laser.
I connected the raspberry pi to the router, and I configured linux network.
Then I tryed to ping 192.168.1.10. But I failed. The result is From 192.168.1.100 icmp_seq=12 Destination Host Unreachable.
My linux system version is ubuntu 16.4,ros system is kinetic. I think that it is version which caused that. Because my student can ping successfully use the same equipment. But his system is ubuntu 14.04. Unfortunately, I can't find the solution about that.
Please,I am going to breakdown.

If wireless not working, maybe you can try to to connect a line to the router for testing(not deploying). It will be more stable.

Have you tried to connect a cable and use DHCP to allocate one ip for you? Is this kind of setting able to ping 192.168.1.10?
