My system is Xubuntu 16.04 LTS. Recently a new fiber router has been installed, but even though I'm connected to it via WiFi, I can neither browse nor use any command that requires an internet connection. The odd thing is that other computers connected to this same point and my own cellphone can browse normally.

I am using DHCP:

The command netstat -rn shows the following:

  • You are talking about a WLAN access point that is also your router? And other devices get routed over this access point, while your computer works with other access points and only the combination of the new AP and your computer doesn't work? Everything right so far? Now step by step: do you use DHCP? Do you receive an IP at all?

  • Yes, we all connect but only I cannot browser anything. Yes, it is all DHCP and I also receive an IP by executing ip route show | grep -i 'default via'| awk '{print $3 }'

  • Okay, I suggest to put this information in the question (someone already downvoted). And also include the answer on netstat -rn

  • Check if IPv6 is in use (-6) and not shown here. Where does the APIPA(169.254.*.*) address come from? Can you ping the gateway? Can you ping google-dns( What is you nameserver? nslookup bbc.co.uk May 23 '17 at 6:40

As mentioned in the comments you are able to ping but can't ping google.com. The problem resides in your DNS-settings. Some of your four DNS won't resolve addresses correctly. You might try an other DNS-server e.g. by entering, or in your Network-Manager in the IPv4-pane.

Prior to this you might check if this works out by trying: host nature.com For me the result was something like

  • Oh, you're Filipino? I am living in the Philippines.

  • @mfgabriel92 Rarely Linux/FreeBSD seem to not like the DNS server/proxy provided by the cable modem while the other devices seem happy with it; I have seen the behaviour yet not had the time to debug it yet. btw, magandang umaga. The same is happening at my father´s house with my Lenovo, however I do visit rarely. May 23 '17 at 7:47

    @mfgabriel92 I do not live there, but I have a Filipina wife. I know enough to recognize the PLDT name. They are (in)famous. I would change the default SSID, and the default password, they can be easily cracked, the algorithm is supposed to be known. However, if at the office, the filipinos are not able to say no when neighbours ask for the password, so I do not know if it is worth wasting the time in that case... May 23 '17 at 8:09

    @mfgabriel92 If you are not situated in EU/USA, there are better suited DNS-servers for you: bestdns.org/for/ph this should speed up resolution. May 23 '17 at 8:18

    @sebastianwagner There are local CDN google mirrors near in Sidney; beware of the quality and security implications of using random DNS servers. myphilippinelife.com/globe-internet-dns-problems May 23 '17 at 8:21
