My version of Edison/Yocto is: 201603141535 (hmmm Pi Day
When I ping elsewhere I get network unreachable.
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 usb0
192.168.42.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
No 0.0.0.0 for the Gateway.
Question: should do the following: route add default gw 192.168.42.0 wlan0
Thank you for reaching out! Let me try to help you with this issue.
First, I would like to know if you need to use the image you're currently using or if you are able to update to the latest image. In case you have no problem with that, here's the link: https://software.intel.com/en-us/iot/hardware/edison/downloads https://software.intel.com/en-us/iot/hardware/edison/downloads.
Now regarding the issue:
Executing configure_edison --wifi solved the problem. I thought I had done this last spring.
Now I have good netstat -rn output. Edison can ping the router and the PC host and the PC host can ping edison.
Regarding: do I need the current image?
I don't need it. I am in experiment mode trying various things. WiFi was next on my list. I could update to the current image but I am afraid something will go wrong and then I'll spend time dealing with that.
Regarding: your other questions.
No need to answer those questions. Especially about the 192.168.42.0 wlan0 in the route command. That was absolutely stupid on my part.
This was not a good use of your time.
