I have Lubuntu 16.04. I can ping whatever via Ethernet. WiFi does obtain IP, but I can't ping 192.168.10.1 which is the same router as for Ethernet

sudo rout -n:

0.0.0.0  192.168.10.1  0.0.0.0  UG  100  0 0  enp1s0

0.0.0.0  192.168.10.1  0.0.0.0  UG  600  0 0  wlp2s0

192.168.10.0  0.0.0.0  255.255.255.0  U  100  0 0  enp1s0

192.168.10.0  0.0.0.0  255.255.255.0  U  600  0 0  wlp2s0

The only difference is the Metric. Could that be a problem?

Thanks

    Which PCI ID and kernel module? See lspci -nnk. – wxl Jul 29 at 17:41
  • Updated above. Thanks. – Rastio Jul 29 at 18:41
  • Maybe router prevents ping from wifi. Check in router admin if there is such option enabled. – Michal Przybylowicz Jul 29 at 19:54
  • I can ping router from my main laptop via WiFi no problem. From Lubuntu, via WiFi I can't ping nothing and cannot do even appt-get install – Rastio Jul 29 at 20:09

    I included the k so we could get info on kernel modules. You can trim out everything except the last bit, which is the "Network controller." – wxl Jul 29 at 20:38
