[SOLVED] Wifi not working on base system

Hi all, I install clear Arch first time and have this issue...
When i use live-iso - wifi works well with

wifi-menu

After installing (with dialog , iw , wpa_supplicant depencies) base system and reloading to it - wifi dont work.
Wifi-menu see my network, but write "CONNECTING FAILED"

ip link

says that wlp2s0 is down.

ip link set wlp2s0 up

did not change the state of wlp2s0

When i try to check my device and drivers with this command:

 lspci 

the system stuck with messages:

 
NMI watchdog: Watchdog detected hard LOCKUP on cpu 1
INFO: rcu_preempt detected stalls on CPU/tasks:
k1-....0: (1 GPs behind) idle=41a/140000000000000/0 softirq=3104/3106 fqs=15001 last_accelerate: 1920/437c, nonlazy_posted: 0, L.

INFO: task jbd2/sda4-8:213 blocked for more than 120 seconds.
Not tained 4.15.4-1-ARCH #1

repeating it much time and after about 10 minutes:

watchdog: BUG: soft lookup - CPU#0 stuck for 22s! [systemd:1]

ps: sorry for my english, it is not my native language.

Re: [SOLVED] Wifi not working on base system

I believe he was asking about your wireless hardware

Re: [SOLVED] Wifi not working on base system

I can't speculate on what Mr.E  really intended, but I doubt the wireless hardware is relevant.  Despite the title, this thread is no longer about a wireless issue: that is working, and the OP just took it in a different direction.

OP, this should be marked as SOLVED, and you should open a new thread for your new issue.  The watchdog lockups seem to come from a variety of causes, but issues with nvidia drivers seem to be among them.  So in your new thread you may want to start with more details of your hardware and drivers (e.g. nvidia) that you are using and whether you've tried any alternative graphics driver(s).
