New install - wireless works in liveusb, but not the system.

I just installed Arch on my desktop (it's been running on my laptop for a couple years) and I'm really struggling with the wireless internet. As it says in my title, the wifi works great when I boot from the liveusb. I use wifi-menu and connect no problem. But when I boot into my new install, wireless doesn't work at all. I've installed all the tools. Actually, I installed everything that was installed in the liveusb environment and then everything that was on my laptop. I copied over the netctl profile from the live environment to my PC, but it still fails.

The card is a Rosewill RNX-N300X and all the drivers are loaded.

Here's the output from 'systemctl status netctl@home'

And here's the output from dmesg

I've looked through the netctl and wireless pages on the wiki, but haven't seen anything that can help.

Re: New install - wireless works in liveusb, but not the system.

Does the device listed in your /etc/netctl/<profile> is the same than the listed from "ip link" command?

"i have similar issues ... my wifi works only when i type dhcpcd wlp3s0 ( wlp3s0 my device)  and i dont know why ..."
Does your profile have dhcpcd enabled?

Re: New install - wireless works in liveusb, but not the system.

try to connect by using wifi-menu (you also need "dialog"), it will create a profile and rename it e.g "home". and then try to connect : netctl start home.

Re: New install - wireless works in liveusb, but not the system.

Let's take a look at the output of systemctl --type=service --no-pager
Also, maybe post your netctl home profile.
