Can't ping after fresh install

I have a netctl profile and I've authenticated with wifi-menu however I still get

temporary failure in name resolution.

I'm able to use wifi-menu when I chroot but not if I boot in normally

Re: Can't ping after fresh install

Care to share it?

I'd speculate that perhaps you didn't update the interface name.

But to avoid speculation, post your network configuration and the output of `ip a`.

EDIT: and I'd gather some of your previous threads, like this one must have seen progress.  Please do not abandon them.  If they are solved, mark them as solved.

I'm not sure how I'd post the output as I can only use my phone.

Is there anything in particular I should look for?

Re: Can't ping after fresh install

@860lacov, if you set the device up, netctl will refuse to manage it.

@aura, which profile do you try to start?
Are the blank lines in either?

Anyway, the error means you've no working dns server.
1. the "ip a" output doesn't cover an established network connecion (no link is up and you've no carrier nor IP either) - is this supposed after an attempted connection w/ wifi-menu?
2. After connecting w/ wifi-menu, can you "ping 8.8.8.8"?

I have run

netctl start myNetwork

and

netctl enable myNetwork

so it should connect at boot correct? Plus I try connecting with wifi-menu. Yes the ip a output is after using wifi-menu.

ping 8.8.8.8

ping: connect: Network is unreachable

Re: Can't ping after fresh install

The "ip a" output does not suggest a successful interface configuration.

netctl status myNetwork
