Wifi working, but no internet connection

I have wired and also wifi connection.

Wired connection internet works, while the internet of wifi not working

If connected to wired and also wifi the following is the output of ifconfig.

If using only wifi it pings to 192.168.0.1

$ ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
64 bytes from 192.168.0.1: icmp_seq=1 ttl=64 time=10.7 ms
64 bytes from 192.168.0.1: icmp_seq=2 ttl=64 time=7.82 ms
64 bytes from 192.168.0.1: icmp_seq=3 ttl=64 time=12.0 ms
64 bytes from 192.168.0.1: icmp_seq=4 ttl=64 time=7.14 ms

whereas ping to google.com it does not show anything. it does not go further.

/etc/resolv.conf is

nameserver 192.168.0.1

route when on wifi:

simha@gauranga ~ % ip route show
default via 192.168.0.1 dev wlp3s0  proto static  metric 600 
192.168.0.0/21 dev wlp3s0  proto kernel  scope link  src 192.168.5.245  metric 600 

route  when on wired:

simha@gauranga ~ % ip route show
default via 192.168.0.1 dev enp2s0  proto static  metric 100 
192.168.0.0/21 dev enp2s0  proto kernel  scope link  src 192.168.5.113  metric 100 

I am not able to understand the problem.

All this happened, after i upgraded archlinux.

Re: Wifi working, but no internet connection

This is just for my interest: can you show your

route

and did you make the subnet yourself?

as for the problem:
What are you using for connecting. networkmanager or wicd or manual?

Re: Wifi working, but no internet connection

How about `ping 8.8.8.8`?

Are you infected with Wetiko?

I am using networkmanager. I edited my question and shown the output of the route.

Re: Wifi working, but no internet connection

see if your wifi mod is loaded in the kernel mods

ip addr
ip link show dev wlp2s0 
lspci -vvv |grep wifi
sudo lspci -knn | grep -i net -A2
lsmod|grep YOUR_WIFI_MOD

systemctl status NetworkManager?

Aside from this problem, do you really need NetworkManager. I use Wicd which seems not so complicated.
If you want try uninstall Networkmanager:

pacman -R networkmanager networkmanager-dispatcher-ntpd

Install wicd and follow the archwiki for wicd(you know where)

Re: Wifi working, but no internet connection

I dont know it worked on its own, didnt do any changes.

In wifi setting: there is cloned Mac address. I deleted and kept it empty. then it worked
