No Internet (eth0 or WiFi)

Help and Support Vero 4K / Vero 4K +
1

Hi all,

Firstly, i know there are a number of topics around internet connection issues, and I’ve trawled through many of them in vain. So I’m hoping that someone can help me, as non of the other posts have helped resolve my issue thus far.

I have a 200Mbps fibre connection and I have 2 Vero 4k devices (one in my lounge and one in the master bedroom). One is connected via WiFi and the other via Ethernet cable. Both are running the November 2019 release. Neither devices are able to connect to the internet. they both say that they are connected to the network and are able to display content from my content server (which is in my office), but neither of them are able to update (OSMC or library) as they cannot connect to the internet. All other devices on my network are able to connect regardless of connection mode (wifi / ethernet).

What I’ve tried so far:

  1. Changed from wifi to ethernet (both devices)
  2. Changed from DHCP to static IP and back.
  3. Checked the /etc/resolv.conf file (entry looks correct, pointing to my router - 10.0.0.2).
  4. Reset the .kodi file (ssh, stop media center, mv .kodi file, start media center).
  5. Complete re-install of OSMC on the Vero. I downloaded the Nov 2019 version.

Is there a known issue with this version? all other devices (mobile, desktops, tablets, TVs) are all able to connect to the internet (some are running on DHCP and others have a static IP). And if not, what else can I try to resolve this issue?

Thank in advance for any assistance.
Michael

Since you can SSH in, try a few things:

ping 8.8.8.8
traceroute 8.8.8.8

That will give an idea of if it’s a DNS problem or not.

I haven’t tried a traceroute. but i did try a ping.

i am able to ping my router 10.0.0.2
when trying to ping 8.8.8.8 the request simply times out.
i did this vis SSH (Putty) from my laptop. at the same time my laptop was also connected to then same wifi SSID and was able to ping 8.8.8.8 without any issue

If you can’t ping 8.8.8.8, then you have a network problem. Something in your router is blocking the Vero. Check your firewall rules.

What does the output of

ifconfig

show?

5

what is output of:
ip addr
ip ro

6

I’ll have a look when i get home.
does the Vero use any special protocols or ports that the default firewall on my router might be blocking?

7

No

Looks right.
So ping 10.0.0.2 works but ping 8.8.8.8
How about traceroute 8.8.8.8?

so it looks like the router is blocking traffic. but i don’t understand. because every other device on my network has no issue. like i said in my original post, i have smart TVs, laptops, servers, AV receivers and mobile devices all connected via ethernet and wifi. so i’m lost.

12

Me too. What router do you have?
Do you have different firewall rules for IP segments?

13

its a Zyxel VMG3625-T20A

i’ve tried turning the firewall on the router off, no change.

14

Well maybe just for testing temporary switch of one of the device that are working (and assign that IP to the Vero for testing).

15

I’ll give it a shot. i did try changing the Vero to DHCP but i’ll try a different static IP

16

I tried on a completely different IP address. also no difference.

My last resort is to try restoring an older version of OSMC like like october 2019 and see if that works… not sure though

17

Could my switch be causing an issue. i replaced my 10/100MB swtches with 2 tp-link gigabit switches

18

I wonder about the gateway address 10.0.0.2 … what is 10.0.0.1 in your network? Is 10.0.0.2 the right gateway to use?

19

10.0.0.2 is my router address.

nothing is on 10.0.0.1

and my router is configured to lease out addresses from 10.0.0.3 - 10.0.0.254

subnet is 255.255.255.0

all other devices connected to the router are all able to connect to the internet

20

The switch shouldn’t affect the WiFi connection, though it might be worth excluding it from the wired test.

It’s unlikely to be an error on both of your OSMC devices. A quick test is try to reboot the router and see if there is any QoS enabled.
