How do I get connected to the internet?

I over wrote my wired computer with Ubuntu. I've put the HD aside, hoping I can rescue stuff off it. I have installed an SSD instead and loaded Ubuntu, but can't get it to connect to the internet. The router is a fritzbox and other computers in the house are connected wirelessly ok.
I've looked for linux drivers for my network adaptors - for my stand alone network adaptor TG-3468, and for my motherboard - Gigabyte GA-H67MA-D2H - which has a built in network adaptor. But neither seem to have linux drivers. I wondered if I should buy another network adaptor that is good for linux but had trouble locating anything except a Sisco-Lynx that couldn't be sent to Australia.
What should I do please?

On a quick googling, your board seems to have an r8111 chip, which I think it's supported by the r8169 (or r8168) in-kernel module. But I haven't one of those to test.

It seems your external card uses the same chip (according to this). So the problem must be that your distro doesn't ship that driver by default, for some reason.

Anyway, you can check yourself by using "lsmod" as root in your terminal. Depending on the distro one of these might work.

Code:

$ sudo lsmod

### or

$ su -c 'lsmod'  <then enter password when prompted>

thanks i92guboj

When I typed in "$ sudo lsmod" I got a lot of lines, one of which said, "r8169 56321 0"

Does this mean the Alternate CD of Ubuntu 12.04 that I used to load the OS(=distro?), was deficient in the driver I need?

[When I typed in "su -c 'lsmod'" it returned "su: Authentication failure" (I repeated this twice).]

That means that the driver is loaded. Can you post the output of these commands?

Code:

$ ifconfig

$ dmesg | grep -i net

If they don't work, put "sudo" in front of each line as you did above.

also this information mite be helpful in diagnosing:

Code:

echo uname: && uname -a -m -p && echo lspci: && lspci && echo lsusb: && lsusb && echo lsmod: && lsmod && echo ifconfig: && ifconfig && echo ifconfig -a: && ifconfig -a && echo iwconfig: && iwconfig && echo resolv.conf: && cat /etc/resolv.conf && echo route: && route -n

some of this may suffer translation loss because I saved it in Word format so that I could copy and paste it to this Windows computer.

I came across this last night http://ubuntuforums.org/showthread.php?t=1964200 I wonder if it had relevance... what do you think schneidz?

Most of that info is useless. However, it's strange that you said this above:

But now, in your lsmod output I can't see the network module:

And no network module, of course, means no network at all. That's it, unless you have it compiled statically into your kernel. I am still interested in seeing the output of "sudo dmesg | grep -i net" that I asked for above ;)

Sorry about that! I half-followed the previously mentioned link which said to blacklist the old r8169 and install a new one (I couldn't manage to install the new driver.) So now I've unblacklisted and rebooted: I've also included the other info you asked for which I accidentally deleted last time without realising it. Thanks for your patience! :)

I didn't see the link you are referring to, can you paste it here? As said, i don't own one of those so there might be any issue with it that i am not aware of.

Another thing. Now that you have the module loaded, what does ifconfig says? Also, please, pastte the whole dmesg if you can.

google(02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01))[1] = http://askubuntu.com/questions/19861...n-ubuntu-12-04

My current thought is: is there any chance for a kernel upgrade in ubuntu or whatever distro you are using? 3.2 is quite old by now, and before complicating yourself with 3rd party stuff that will break every two weeks, I suggest that you try an up-to-date kernel. Since there's a driver for your hardware in the kernel there's a very high chance that any bug affecting this concrete driver has been fixed.

I can't test myself, as said, but it seems that this chip has been problematic.

I've seen reports of some people that managed to get this 8111/8168 chip by using the r8169 driver AND having the correct firmware installed (dmesg should report something about missing firmware when loading the r8169 driver).

If not, then that guide that you posted should help, but before downloading random drivers from anywhere, I'd check if there are packages with the string "8168" in synaptic or whatever package manager you're using. In any case, whatever solution you try, stick to it and ask back here when in doubt. If you go bouncing between many ways it's difficult to keep track of what you are doing, besides the fact that one action in one of the ways might invalidate the others, like the issue I detected above about the r8169 driver not being loaded.

So far, your options are (to summarize):

r8169 from the kernel + the correct firmware,
r8168, if possible, from your package manager, for this you need to blacklist r8169 it seems

Pick one, proceed, in any case, the procedure to check what's failing is the same.

lsmod, look for the driver you are working with, and double check that the other driver IS NOT loaded, two drivers fighting for the same hardware is no good
check the output for dmesg, specially for things about "eth0", "net" and "r8168" (or 8169), if in doubt, paste the relevant lines here and we'll try to give you some advice on how to proceed
if everyting is right, check ifconfig, eth0 should show up in there, here you need to check if you have an inet address, if not then you should probably use dhclient, dhcpcd or whatever ubuntu uses these days to get an ip address via dhcp

Please run "sudo modinfo r8169". This will print out info on whether firmware is loaded, and what the firmware files are in /lib/firmware/.

If the device is working, you still need to configure wpa2 and networking before connecting to the internet. The latter may be as simple as selecting DHCP.

a couple of suggestions, if I may...

run the dmesg without grep -i net.

Then carefully look thru the verbose dmesg output for the stanzas where the kernel initializes the wifi driver for the 8111. There should should be an assigned device nmemonic shown (ie: wlan0 or ath0 or rausb0 etc.).

Now, Realtek wifi devices typically require firmware to be loaded. It is likely that the driver is detecting that firmware is required but is NOT loaded. You may have to find the appropriate firmware file, download and install it into the firmware subdirectory.

Also, when you run the ifconfig command, be sure and turn that device on first (ie: ifconfig wlan0 up) and then repeat the ifconfig command without arguments (ie: ifconfig) This should show information about that device with various details (ie: MAC address, recieve/transmit byte counts, memory-mapped I/O ports, and IRQ). If you attain this point in the device initialization, it is ready for use. NetworkManager (or wicd) should then initialize it with an IP address and proper routing.

As an alternate example, so you can view what sorts of messages you can expect to appear in the system messages file when a WiFi device is detected and initialized, I plugged in a Edimax USB WiFi that I have here. It is not a Realtek device, but is a Ralink device, but the messages will be quite similiar. I then extracted the kernel messages which appeared in the messages file for your viewing pleasure:

My system runs CentOS 6.2 with kernel 2.6.32-279.2.1.el6.x86_64 #1 SMP instead of Ubuntu but the kernel messages should be quite similiar.

thanks guys for your suggestions and interest...

I think I've made progress. Here are some edited current lsmod, ifconfig and dmesg printouts after a fresh reboot - below. I think I've got the new driver in there working - have I?? In which case, maybe I 'm up to configuring my network connection? if so can I get ubuntu 12.04 to set up my connection automatically?

So your network card is detected, and it even gained an ip.

Can you ping some external server? Please, post the output for these:

Code:

$ ping -c 2 google.com

$ ping -c 2 8.8.8.8

If this works, you should already have internet access. If the first command fails but the second works, then you surely have a DNS resolution problem which we will address shortly.

By the way, I assume you are connecting to the internet via an ADSL modem or a router, right?
