[Bug 1114948] Re: unable to access server on lan by hostname on wi-fi

[Stéphane Graber]

.local is using avahi which relies on working multicast.
Changes are that your wifi is somehow breaking multicast leading to resolution failure.

If .local is actually operated by an actual DNS server and not through
avahi, then you should move away from .local and use anything else.


I'm marking this bug as Invalid on the basis that it relies on avahi/mdns and so isn't even remotely going through the standard DNS resolving process and so can't be a resolvconf bug. I'd highly recommend reviewing your access point settings, looking for anything related to multicast in there as that's the most likely problem, additionally, those routers don't typically route multicast, so if your wifi is on a different subnet than your wired network, .local resolution won't work either.

** Changed in: resolvconf (Ubuntu)
       Status: New => Invalid

Title:
  unable to access server on lan by hostname on wi-fi

Status in “resolvconf” package in Ubuntu:
  Invalid

Bug description:
  When using wi-fi, i'm unable to access my server by its hostname. It
  works fine on an ethernet cable. On wi-fi, I'm only able to access my
  server by IP address. The server can ping any computer on the network.
  The server is hardwired, and the laptop is on wi-fi.
