Unable to access wired or wireless ethernet connections

rmcellig · 04-23-2014, 06:54 PM

I have a dv6 laptop that has been working fine up until today. I cannot access the internet wired or wireless. I tried different cables. No dice. Could this be a driver issue?

What can I do to check if it is that I can post back? If it is driver related how can I update it seeing that I am running Linux?

I tried booting from a Puppy Linux CD, booted from my Peppermint 4, Ubuntu 14.04 partitions as well from my HD with the same result.

What do you mean by "the internet doesn't work"? Can you access any local computers? Can you ping your router? Can you access the internet from other computers? Can you ping localhost? If you see that the internet is accessible in principle, it's likely something is wrong with your network configuration.

Simple steps to start troubleshooting your network configuration (not necessarily in this order, and probably not complete):

The commands ifconfig or ip a tell what state your network interfaces are in. What do they say?
Basic network configuration is in the file /etc/network/interfaces on Ubuntu (don't know how it's done on Puppy). What does it look like?
Your wired interface is named in the interfaces file. Probably eth0. Do you see anything in the system log /var/log/syslog about eth0?

All other computers on my LAN access the internet with no problems.

I cannot access any shared devices on the HP either. I will post back the results from the list of things to check.

Note how eth0 has no IP address. The loopback interface lo, on the other hand, has one:

Your network devices are managed by NetworkManager. I don't see any other device mentioned than eth0 - are you sure your WLAN interface is enabled at all?

r8169 0000:03:00.0: eth0: link down indicates that there is something wrong with the ethernet interface. You get such a message when the cable is disconnected, for example, but it could also be that the wrong driver is used. r8169 is the driver for a Realtek 8169 interface.

What interface does your PC have? You can figure this out from the BIOS (most reliable) or by checking the quickspecs for dv6 on the HP web site.

It would also be interesting to see other r8169 messages in your syslog, or messages containing the word Realtek.

rmcellig · 04-23-2014, 09:34 PM

WLAN must be enabled because my other computers work fine accessing the internet.

I mean WLAN on your notebook. I don't know the dv6, but my notebook (also HP) has a button that switches WLAN off. And I am sure this can be done from the BIOS as well. From the limited information I have, it seems to me that your kernel doesn't see a WLAN device. Or perhaps it's missing the driver.

How to find out? One would have to look through syslog for messages indicating an unknown device, or a configuration failure.

Something I forgot: lspci -v would be another useful tool. It dumps a verbose listing of all devices on your PCI bus and should tell you what wired or wireless devices currently exist. lspci -k shows what drivers are connected to the devices (and lspci -vk does both). This is what I get on my system:

Code:

Take a look in your BIOS and see if your network chip or card is enabled.

I just rebooted my computer into Linux Mint 16 and was able to get a wireless connection with full access to the internet.

I still need to get the actual wired internet connection going. I don't carry this laptop around. It sits stationary in my house all the time and I would much rather use a hard wireed connection like the rest of the computers on my LAN.

Well, according to the Realtek web site, that looks like the right driver for this device.

It's a pity I don't have direct access to your PC. I would have another look at the syslog file (perhaps you can just attach it to your next reply?).

Another test I would perform is disabling NetworkManager, thereby removing one potential source for error, setting up a static IP address for the wired connection and seeing what, if any, error messages pop up.

Are you able to set up a static IP address? I don't know if Ubuntu has a GUI for that task; it can however be done by modifying the /etc/network/interfaces file. You would then temporarily stop NetworkManager (service NetworkManager stop, I believe) and initialize your interface with ifup eth0. I would then hope you get an error message, or a new message in the syslog, which would give us more clues. Or perhaps it would just work, which might indicate a problem with NetworkManager.

For some reason, I now have full internet access wired and wireless. I also did something drastic but I think its a good idea. A while ago I ordered the system restore CD's from HP. After all these years I decided to use them so that the HP is now exactly like it was when I first got it. The OS is Windows 7. So from here I plan on installing Linux again into a couple of partitions which I will use more than win7 but at least I have windows on it in case something goes wonky or in those very rare instances where I need to use Windows.

I would like to thank everyone in this thread for your very informative suggestions which I learned a lot from. Very impressed!!
