Can't use wifi after installing

So I recently installed arch and booted into it.
During the install my wifi was working. Now after installation. iwctl shows that I'm connected to a wifi . I have also enabled network manager but doing ping google.com
shows this:
ping temporary failure in name resolution
and ping 8.8.8.8 shows:
ping connect network is unreachable
doing a pacman -S gives many lines of error with failed to retrieve file.
I would like to know what's causing this issue and if there is any fix.

Re: Can't use wifi after installing

What module was used for the wireless interface during installation?  Wireless#Check_the_driver_status.

Re: Can't use wifi after installing

Did you configure iwd to do dhcp or use a separate dhcp client?

Edit: or maybe a static config? Anyway, how did you setup the IP?

Re: Can't use wifi after installing

Installing a desktop environment has certainly not fixed your wifi-setup…
