Yes, in my case it is:
static routers=192.168.0.1
The line is towards the top of /etc/dhcpcd.conv just after the static ip_address line. I have also tried putting the added lines at the bottom of the file with no obvious difference in behavior. The service dhcpcd is running.
It does seem to be an issue with the gateway setting, but I am not sure where exactly it gets set. When running “ping website.com”, ping will accurately report the IP address of website.com so the nameserver setting is ok, but then cannot reach it so no packets are returned. However ping does work going to 192.168.0.x addresses.
Running ifconfig on the Shake and Boom gives very similar results, with neither one reporting a gateway setting for eth0 . The route command also gives essentially the same information on the Shake and Boom, but maybe I don’t know how to spot the gateway setting in the output. Is there some way to display and change the gateway address on a running system?
