Re: cannot connect to wifi , wifi inteface not listed

Which DE do you use? you can try a gui graphical wifi manager.
first connect to the internet, using ethernet or usb, and run:

sudo pacman -S networkmanager
sudo systemctl enable NetworkManager.service.

restart your pc it will be on the desktop panel notifications area.

@keepers
What would a GUI or networkmanager help here?
The wireless interface isn't available, so it cannot be used by fancy-stuff™.

@abhi, let's first check what your wifi interface actually is. Please post the outputs of "lspci" and "lsusb".
Also the complete "dmesg" (you can use the tip from https://wiki.archlinux.org/index.php/Pastebin to redirect it into a pastebin service) - maybe there're firmware or bus errors for the device recorded.

Welcome to the forum.
