I seem to be having a weird issue on OS X Yosemite (10.10.5) - When I have my wifi connection set to DHCP, everything works fine. But, when I switch to manual IP (even with the exact same IP config that I get from DHCP), routing to internet sites fails. I can ping local computers, but, pinging other sites results in "No route to host". I would appreciate any ideas on how to fix this. Thanks

Edit: The routes that I have after setting a manual ip are

Routing tables

  • I'd just switch it to DHCP + manual address, then the DHCP server is still in charge. – Tetsujin Jan 7 '16 at 12:26
  • I actually need to use a different router/gateway than the main one which does the DHCP. However, any kind of manual setting - even with router as the main DHCP one - fails – georgemp Jan 7 '16 at 12:28
  • 2 routers on the same subnet? – Tetsujin Jan 7 '16 at 12:46
  • Only one does DHCP. The other is a Linux VM that uses a VPN to connect to the internet. Other devices don't have an issue connecting to either – georgemp Jan 7 '16 at 13:05
  • The Linux VM is on a different machine – georgemp Jan 7 '16 at 13:17

Looks like I am affected by the issue posted here. The proposed solution of adding a new default route works. If anybody else, has a better solution, where I don't have to do that everytime - when I switch between DHCP and Manual - I would love to try it. Thanks

Solution posted there is to add a default route to the router IP

sudo route add default 192.168.x.x
