Wifi is connected but can't access network.

I have had this problem since fresh install of arch. My notebook is connected to wifi.

ip addr:

3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 10:0b:a9:ab:73:cc brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.121/24 brd 192.168.2.255 scope global noprefixroute wlp3s0
       valid_lft forever preferred_lft forever
    inet6 fe80::120b:a9ff:feab:73cc/64 scope link 
       valid_lft forever preferred_lft forever

But i can't ping any addresses, not even my router at 192.168.2.1.
I then proceed to systemctl restart netctl-auto@wlp3s0.service a couple of times and then it works again. Any ideas what the problem might be?
Thanks for your help.

Re: Wifi is connected but can't access network.

Please post the output of

systemctl list-unit-files --state=enabled

What is the exact error message when you attempt your ping commands?

Is there anything relevant in the journal?

Re: Wifi is connected but can't access network.

Hi. Mine is different from yours:)  Yours have additional paramaters. See the difference. Maybe it is related?

Try to connect via raw (i meaning directly) wpa_supplicant command. Are you able to connect as such?

I am using raw wpa_supplicant to connect. I think it is best for simple cases.

2: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff
    inet 192.168.**.**/24 scope global wlan0
       valid_lft forever preferred_lft forever
    inet6 ****::**:****:****:****/64 scope link 
       valid_lft forever preferred_lft forever

Thanks for your replies. The problem is very inconsistent. I'll try your tips the next time it happens and will post here.

^ This would suggest that the problem may be hardware related, check if the card is seated properly.

Re: Wifi is connected but can't access network.

Not if there's a race conditon due to competing services.

@archiemarshall, is the "ip a" output from a situation where the network was "unavailable"?
