I have just finished installation of arch on my laptop. Wired ethernet connection was not possible here but I managed to complete the installation process using WiFi and wifi-menu command. On launching the OS, I noticed wifi-menu doesn't work anymore and installing it from Pacman would require an internet connection. So, can I use the live USB stick or some command to install a desktop environment on WiFi?
I tried to use my phone's connection using USB tethring but it didn't work initially because of missing dhcpcd command. So, I used a live USB to chroot into the system by $mount /dev/sdx /mnt $arch-chroot /mnt After this, I fixed the broken packages and installed dhcpcd by $pacman -Syy $pacman -S dhcpcd $exit Then after rebooting into arch and turning on my phone's USB tethring, everything worked fine. To test your connection, use $ping -c 3 google.com
