.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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1114948 Title: unable to access server on lan by hostname on wi-fi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1114948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
