Re: [SLOVED]could not connect to network

What does this mean?

could not connect to the network again

You've got an interface which is up and has an IP assigned, so maybe start with *HOW* you attempt to "connect to the network" - and how you determine the failure.
Also read up https://wiki.archlinux.org/index.php/Wi … nual_setup to produce some usable output for various connection steps.

Sidenote: please wrap output in "code" tags, also edit your initial post itr.

Re: [SLOVED]could not connect to network

thank very much, i found the problem. files under /var/lib/pacman/local/linux-firmware-20180314.4c0bf11-1 were lost because of the forced shutdown, then there was problem with the driver...
