[SOLVED] No networking after upgrade to 14.1

mattca · 11-10-2013, 03:16 PM

Hey guys, the update seems to mostly gone well, except my networking is no longer working at all. At first I thought I just had to reinstall my wireless drivers, but wired isn't working either. It reports a connection and receives an ip address from my router, but nothing is working.

Any ideas?

What kind of wireless card do you have? Do you have a firewall script installed?

ReaperX7 · 11-10-2013, 03:28 PM

Run netconfig and try resetting the network configuration.

No firewall, and I'm trying to get wired working before looking at the wireless.

Thanks for the suggestion, it unfortunately did not help

What do you mean by "nothing"? Could you provide output of "route"? does the "ping" command with an external IP address as argument work? And with a domain name? What if you simply type "dhcpcd eth0"?

Also, please provide output of "ifconfig"

Is it possible that your card is at eth1 instead of eth0? When I booted after a fresh install I had no internet either, so I needed to modify inet1.conf for this reason.

Something funny with /etc/udev/rules.d/70-persistent-net.rules?

Hey,

I had a problem with my Wired Network connection, I changed DHCP[0]="no" in rc.inetd.conf and that solved my problem with Network Manager in KDE.

# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="no"
DHCP_HOSTNAME[0]=""

Hope that helps.

Bertman123 · 11-10-2013, 07:24 PM

try iwconfig and see what connections are listed.

Thanks for the response. Here's the output requested:

route

Code:

ifconfig

Code:

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Pinging an ip address and domain name both produce the same result - 100% packet loss. Oddly enough, when pinging a domain name there is a pause at first, then it shows that it is pinging the associated ip address. I don't know a lot about networking, but it seems odd that it would be able to find the ip address without a connection.

Typing "dhcpcd eth0" produces a message that tells me dhcpcd is already running.

I'm hoping I've done something stupid here, and that it's a simple fix.

Didier Spaier · 11-12-2013, 07:05 PM

I'm not that good in networking, but here I have 192.168.0.254, not 192.168.0.1, as gateway.

You could try this:

Run netconfig, choose 'loopback' and confirm. This will reset any specific configuration
Run netconfig again, but this time choose 'NetworkManager'
type: /etc/rc.d/rc.networkmanager restart

What kind of ethernet card do you have? Can you post the output of lspci?

On 14 did everything work out of the box? Or did you have to install any proprietary drivers?

What kind of wireless card do you have (just curious)? It's odd that things would just stop working.

Wired internet has always worked out of the box on this machine - on 13.0, 13.37 and 14.0. Wireless never does, but I don't expect it to.

As an update, I did a fresh install and am having the same issue. I was hoping that I missed something when I was updating, but it appears to do this out of the box. I'm also trying KDE for the first time (I usually use ratpoison), hoping that the automated tools would make it easier. But, network manager doesn't report any connections or devices. Under the "wired" tab, all options are greyed out.

Any ideas anyone?

perbh · 11-12-2013, 09:57 PM

/etc/resolv.conf ??
I have seen funny results if this is empty (though it _should_ be populated by networkmanager)
At least make sure that the following are present:

Quote:

nameserver 192.168.0.1
nameserver 8.8.8.8

From ifconfig (above), you obviously have an ip-address, so it must be the name resolution that's not working.
Have you tried to ping a numeric ip-address? (eg. ping 8.8.8.8)

mattca · 11-12-2013, 10:18 PM

/etc/resolv.conf was populated by NetworkManager, at least with 192.168.0.1. I added 8.8.8.8, but it disappeared after restarting. It didn't seem to help, in any case.

I thought name resolution might be the issue, but I can't ping by ip address either. I can ping my router (192.168.0.1) as expected, but pinging 8.8.8.8 just hangs.

Also if it was just the name resolution, I would expect network manager to recognize that I have networking interfaces...

I'm really confused, my wired connection always *just works*
