conected to router but no internet

[sd3782]

Hi,

I've seen lots of other issues similar to mine on this forum and others, but had no joy in resolving this problem.

I can connect to my router web interface, using both wireless and ethernet cable, but cannot connect to the internet with either.

I can't ping any IP address or hostname.

When I type route into the terminal, I get:

Destination Gateway     Genmask       Flags Metric Ref Use Iface
default     192.168.1.1 255.255.255.0 UG    0      0   0   eth0
192.168.1.0 *           255.255.255.0 U     1      0   0   eth0
loopback    *           255.0.0.0     U     0      0   0   lo
default     192.168.1.1 0.0.0.0       UG    0      0   0   eth0
default     192.168.1.1 0.0.0.0       UG    0      0   0   eth0

There are extra 'default' destinations in there, because of things I have tried from other posts.

I have had internet working. It was working for months, but it all stopped working when I installed Skype, vpnc and kvpnc (VPN Client GUI).

I don't know if this is just coincidence. I did get connected to my VPN, but shortly after installing Skype, everything outside my local network (i.e. internet and VPN) stopped working.

I'm writing this from another laptop on the local network, so the internet obviously working fine - just not from my own laptop.

I'm running openSUSE 11.1 (i586), KDE 4.1.3 "release 4.10.4". And in "sysinfo:/" it says Network Status: "You are online"

Like I said, internet doesn't work for both ethernet and wireless. Can't ping anything. I can access router web interface at 192.168.1.1

Any help would be greatly appreciated!

Thank you.

Hi, thanks for your reply, but that didn't help. Any other advice?

It was working for months, it's only just stopped working for the last couple of days.

Thanks,

Thank you.

The first 'default' route must be deleted. It being the first one it is used (and it is wrong) and not the other two (which are correct and equal to each other, so only one is needed).

Why has 192.168.1.0 got a metric of 1 - usually this would be zero. Are you sure you don't have a problem with your internal firewall blocking everything?
Also 192.168.1.1 appears 3 times.

OK, thanks all for your help, but still no joy.

I have restarted, and the output of route, with no messing around to it, is as follows:

Destination Gateway     Genmask       Flags Metric Ref Use Iface
192.168.1.0 *           255.255.255.0 U     1      0   0   eth0
192.168.1.0 *           255.255.255.0 U     2      0   0   wlan0
loopback    *           255.0.0.0     U     0      0   0   lo
default     192.168.1.1 0.0.0.0       UG    0      0   0   eth0

I don't know what the metric is or why it's non-zero where it is. Any more advice? Any ideas why it just stopped working two days ago?

Thanks,
Sam

This is still strange, bercause now wlan0 emerged with was not in your original story. Normaly only one NIC accesses one network. You have two NICs connecting to 192.168.1.0/24.

While I admit that it is a bit strange that the metric is used here, I am not sure if it matters. In any case we should first be certain that the routing table is correcet, so please tell us more about the popping up of wlan0.

[sd3782]

I use 192.168.1.1 to login to the router web interface.

I don't know why the wireless wlan0 was there in the route table. It's not there anymore... although when I click on the NetworkManager tray icon, it says my eth0 (DHCP) and wlan0 are connected, but shows the picture of the ethernet cable.

So now it's just:

Destination Gateway     Genmask       Flags Metric Ref Use Iface
192.168.1.0 *           255.255.255.0 U     1      0   0   eth0
loopback    *           255.0.0.0     U     0      0   0   lo
default     192.168.1.1 0.0.0.0       UG    0      0   0   eth0

Also, it takes a long time to return the routing table when i type in route. In fact when I type 'time route', it takes real 0m45.039s. Is that normal?

Thanks again for all your help.

The routing table now looks nice. But try get rid of all references to wlan0 so it does not return somewhere.

About the long time of route: Does this also happen with route -n? Because route -n does not consult DNS and when DNS is a problem it takes time to time out on every IP address in the routing list.

And what about trying to ping to 130.57.4.15. This is the IP address of forums.opensuse.org, but of course the using the IP address DNS is not consulted.
