"Temporary failure in name resolution" during installation

At the beginning of the installation I run

ip link

that gives

 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000
    link/ether d8:f2:ca:e8:6a:07 brd ff:ff:ff:ff:ff:ff

than

 ping archlinux.org 

gives

 ping: archlinux.org: Temporary failure in name resolution 

So I run

 wifi-menu 

and choose my wifi, enter name and wpa key. Than the output of the

 ping -c 10 archlinux.org 

says that 0% packet loss which is good as far as I understand.
Than at the point where I should download and install all the packages I run

 pacstrap /mnt base base-devel linux linux-firmware vim intel-ucode 

installation begins but after some time it gives an output like (with multiple error messages)

error: failed retrieving file 'package name' from 'server name': Could not resolve host 'server name' 
warning: failed to retrieve some files
error: failed to commit transaction (invalid url for server)
Errors occurred, no packages were upgraded.
==> ERROR: Failed to install packages to new root

After this I tried again

 ping archlinux.org 

and it gives

 ping: archlinux.org: Temporary failure in name resolution 

so it is like I am disconnected but after running

 ip link 

I get

 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

So I don't see wlan0 anymore. What might be the reason of this?
(a few things that are probably worth mention: 1. I am new to linux and 2.  I had problems on this laptop with wifi previously (I had Ubuntu and occasionally wifi disappears and it stated "Wifi adapter not found" though after reboot it was there again).

Re: "Temporary failure in name resolution" during installation

Welcome to Arch!
Is this just a DNS issue? Can you ping an ip like 8.8.8.8 ?

Re: "Temporary failure in name resolution" during installation

ping 8.8.8.8

gives

ping: connect: Network is unreachable

It seems like i can't connect to my wifi. And in router settings I also don't see my laptop being connected(though it was for some time after I've connected via wifi-menu).

Re: "Temporary failure in name resolution" during installation

Judging from what you've posted , I'm guessing you need to manipulate some DHCP client after you connect with wifi-menu.

Re: "Temporary failure in name resolution" during installation

are you connected to internet?
try wifi-menu
if it doesn't work run rfkill unblock all before run again the above command

Re: "Temporary failure in name resolution" during installation

Thanks for your answers. A small update on my issue. I have started over the whole installation and now ip link gives the following

 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether d8:f2:ca:e8:6a:07 brd ff:ff:ff:ff:ff:ff

As you can see it says BROADCAST and state UP. and ping archlinux.org was with 0 losses. So I have proceeded with installation.

pacstrap /mnt base base-devel linux linux-firmware vim man-db man-pages intel-ucode

works fine this time but during boot loader installation (systemd-boot) when I was making boot loader file i.e. esp/loader/entries/arch.conf (using vim) there appeared a long message with a lot of lines like

[ 4407.061637] iwlwifi 0000:00:14.3: Firmware error during reconfiguration - reprobe!

and many other similar messages from which I understand only that something is wrong with iwlwifi driver. But I ignored this message and finished the installation. And after reboot I get this

[ 2.999180] iwlwifi 0000:00:14.3: Firmware not running - cannot dump error
[ 3.005693] iwlwifi 0000:00:14.3: Failed to run INIT ucode: -5

I can log in using password and it looks like arch is installed but I don't have the connection.
It seems like I am losing wireless connection after some time and I don't know why.

are you connected to internet?
try wifi-menu

wifi-menu does work and I am connected for some time but than it disappears.

I'm guessing you need to manipulate some DHCP client after you connect with wifi-menu.

Sorry, but can you be more specific please?
