[SOLVED] Can't connect to wifi during Arch Linux install

I'm trying to install Arch Linux from scratch following the official installation guide. Although an Ethernet connection is recommended, my computer doesn't have an Ethernet port, so I must use wifi. I successfully connected to wifi using the wifi-menu command, but when I try to ping any site this happens:

ping google.com
ping: google.com: Name or service not known

Any help is appreciated.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

Can you "ping 8.8.8.8"?

What's the output of

ip a
ip r
stat /etc/resolv.conf
cat /etc/resolv.conf

?

I get the same result as any domain name (ping: connect: Name or service not known)

What's the output of [...]

This image is the best I can do without resorting to manual copying... which I would really like to use as a last resort. Of course I would be glad to know if there's a more efficient way of extracting text from the terminal.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

You don't seem to have run the wifi-menu command (successfully) as there are no IP addresses configured on the device nor appropriate routes.
Either that or your local network does not have a (working) DHCP server. Do you set IP addresses manually?

Re: [SOLVED] Can't connect to wifi during Arch Linux install

Why is resolve.conf the systemd-resolved'ohh symlink? Does the installation iso now use systemd-networkd or networkmanager instead of wifi-menu/netctl?

Something brought the interface up, that was probably not wifi-menu (because it should™ have brought it down with the failure) and in that case: wifi-menu will not try to control an active NIC.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

@seth: The latest Arch ISO was migrated from dhcpcd to systemd-networkd.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

You don't seem to have run the wifi-menu command (successfully) as there are no IP addresses configured on the device nor appropriate routes.

I don't know how to determine weather wifi-menu worked or not... (on the installation guide it said only to check it with the ping command). I tried to document my usage of wifi-menu below in hope it will give an insight into the problem:

Either that or your local network does not have a (working) DHCP server.

I read the beginning sections of https://wiki.archlinux.org/index.php/dh … stallation and tried to start dhcpcd with

systemctl start dhcpcd.service

before running wifi-menu, but nothing changed...

This is the output of

systemctl status dhcpcd.service

, in case it helps at all:

Do you set IP addresses manually?

I never had to manually configure any ip address (wifi works on my previous Ubuntu desktop).

Re: [SOLVED] Can't connect to wifi during Arch Linux install

You don't need to start dhcpcd on the live iso, since it's been replaced by systemd-networkd as mentioned.
That being said, now that it's up and running on your live system according to the status output you posted and it'd handling then wlan0 interface, which is waiting for a carrier.
If the wifi_menu connection failed, you most likely entered a wrong passphrase for the network.
What happens if you try to connect via wifi-menu now?
Maybe also try to connect via wpa_cli.

Yeah, my bad for not noticing. Would you like it if I rebooted the system and tried to get status info on systemd-netword/resolved?

So, to summerize my process until now:

- wifi-menu (I have now noticed that I get a frowny face on the far right of my screen, is it important?).
- ping doesn't work
- systemctl start dhcpcd.service
- wifi-menu
- select my network

output of wifi-menu:

Maybe also try to connect via wpa_cli.

Do I need to reboot or can I do this after performing the steps mentioned above?

Re: [SOLVED] Can't connect to wifi during Arch Linux install

The face is a zsh-grml feature telling you that the command failed w/ an error.

- systemctl start dhcpcd.service
- wifi-menu

Don't do that. dhcpcd takes control over the NIC and wifi-menu will refuse to operate it.

I assume what happens is systemd-networkd tries to configure the network, fails but at least brings up the NIC and blocks wifi-menu.

=> Output of

systemctl list-unit-files --state=enabled

Re: [SOLVED] Can't connect to wifi during Arch Linux install

I rebooted the system and just ran wifi-menu wiithout starting dhcpcd.

=> Output of

systemctl list-unit-files --state=enabled

output after running wifi-menu:

Re: [SOLVED] Can't connect to wifi during Arch Linux install

As predicted.
"systemctl stop ..." everything systemd-networkd* and systemd-resolved (they might implicitly stop each other and yell errors because you're stopping a non-running service. that's ok) - start wit the socket.
Then remove the /etc.resole.conf symlink an retry wifi-menu.

Unfortunately I still get the same error... here's what I did in details:

- systemctl stop systemd-networkd.socket
- systemctl stop systemd-networkd.service
- systemctl stop systemd-resolved.service
- rm -rf /etc.resole.conf
- wifi-menu

Are you sure you did not make a spelling mistake when mentioning the /etc.resole.conf file? In assuming that you did, I also tried the steps above, but deleting /etc/resolv.conf instead. Still the result was the same.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

Yes, mega-typo, sorry.

After stopping all those services, was the interface still up?
In case you'd also have to bring it down first.

Honestly, just pick a slightly older iso (the may one is ok according to #6) w/o systemd-networkd getting in the way.
This is getting ridiculous.

Alternatively don't do any of this (you cannot use wifi-menu nor dhcpcd) and see whether systemd-networkd actually works if you establish a carrier w/ wpa_cli or wpa_passphrase, https://wiki.archlinux.org/index.php/Wpa_supplicant
Not as convenient as wifi-menu, though.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

ikr i have this issue too, i've been looking for 4 days straight and none of the guide makes me ping into domain, but it can ping to dns like 8.8.8.8.
ping domain just leave empty and stuck there forever.

so i go back to my old iso image which is 2017 on feb, it can easily connected with wifi-menu no more shit, but i can't install archlinux due to invalid archlinux-keyring, upgrading doesn't help because old archlinux use xz while new use zstd.

it's so weird, it's like i''m looping into no where just to install archlinux again.

New ISO image problem with internet.
Old ISO image problem with keyring while internet works perfectly fine.

Re: [SOLVED] Can't connect to wifi during Arch Linux install

Try the 2020.07.01 release when it's out as there have been a lot of changes to archiso https://gitlab.archlinux.org/archlinux/ … ts/master/

Re: [SOLVED] Can't connect to wifi during Arch Linux install

Or use the 2020.05.01 image (should have functional wifi-menu and not suffer from the keyring issues)

I tried this first and ping finally worked after running wifi-menu! Thanks to everyone for the help.
