[SOLVED] no internet after fresh install

Hi,
So i just installed arch.
after i chrooted out and rebooted i lost my internet connection.
Wifi and ethernet doesnt work.
i did

 lspci -v 

and it says that my network controller and my ethernet controller both have a kernel driver in use (wish i could post the putput of

lspci -v

but i havnt installed a desktop desktop environment so i dont know how to copy/past it).
i tried

 systemctl enable dhcpcd@myinterface
ip link set myinterface up

Re: [SOLVED] no internet after fresh install

Enabling it does not immediately start it.  It will start it on the next boot.

Try:

systemctl start dhcpcd@myinterface

Edit:  More importantly, which tool sets do you plan to use to manage your network interfaces?

I think the one included in kde plasma 5.
But during installation i installed iw wpa_supplicant dialog wpa_actiond.

Re: [SOLVED] no internet after fresh install

The important thing is to pick one, or at the very least, only one for each interface.   You will want NetworkManager for KDE.  Note that Network manager will fight with the dhcpcd service as NwtworkManager will launch its own dhcpcd daemon when it needs it.

Re: [SOLVED] no internet after fresh install

oke so i did

systemctl enable dhcpcd@enp4s0 

and

systemctl start dhcpcd@enp4s0 

and both says

 failed to enable unit : the name org.freedesktop.policykit1 was not provided by any .service files

enp4s0 is my ethernet.

Re: [SOLVED] no internet after fresh install

Those need to be run as root (if you don't have polkit configured/running):

sudo systemctl start dhcpcd@enp4s0

Re: [SOLVED] no internet after fresh install

No.   You need to have something manage associating with an access point.

wpa_supplicant is a dependency of networkmanager,  the other packages presence should not cause issues.

i also installed wicd and wifi radar but i uninstalled them because they where not working but they installed some dependencies is that and issue?
