Hi,

Im a first time linux user and have always wanted to give ubuntu a go, so i installed it when i recently formatted windows.

Basically the problem im having, is that whenever i boot into ubuntu i cant get any network connectivity, although the network manager says that im connected to my home network. I can't ping my router, or connect to my routers web interface via firefox.

Ive tried to do the powerdown with the plug out thing twice to no avail, i also used a script i found to default the use of the r8168 drivers instead of the r8169 drivers. Ive also tried DHCP, manually assigned settings and still nothing works.

So yeah, im completely lost, and also a bit annoyed

any help would be appreciated.

cheers,

Glen.

Erm... hopefully error10 can take a look. It might just be a simple driver issue.

Is that the script you ran?

Is your ethernet controller, so do

Code:

Code:

lsmod | grep -i r81 && lsmod | grep -i rtl81

to see what modules are loaded.

Code:

Code:

r8168                  41104  0

I assume that means im using the correct driver?

Ok you may need to update the kernel, do
Code:

Code:

uname -a

to see what it is at currently.

Ah that kernel is slightly outdated, but I can't seem to find a link on the Ubuntu site to the kernel deb.

Do you have another NIC you could use to get connectivity and update the kernel?

Well, that also doesnt work.

Compaq NC3121 Fast Ethernet NIC

^^ Thats the other one i had lying around, but that has the exact same symptoms. on boot, it says that its connected to the wired network, but it has absolutly no connectivity at all.

About ready to give up

That is strange, maybe the network daemon is failing somewhere. Try
Code:

Code:

sudo /etc/init.d/networking restart

hmmm said something along the lines of:

ignoring unknown device eth0=eth0
[OK]

Ive had enough for today though, far too annoyed to keep trying (been trying most of today and last night when i first installed ubuntu) so im gonna just play some games or something. If you think of anything, post it here, and ill try it later and post back the results.

Yeah I know the feeling, it sucks with something goes wrong with your main rig. If the kernel update doesn't work then I'd suggest blacklisting the current r8168 module and building it from source, trouble is I can't find the source code for it on Realtek's terrible site.

I may end up trying mint instead...download the latest version etc, hopefully it will work...

gill

Discussion Starter · #20 · Mar 3, 2009

Ok well im downloading mint, which has the latest kernel ( i think ) so atleast that problem will be out of the way. Still has a while to go, downloads from the mint site is rather slow, so ill get it up and running and post back here with the result and questions if needed.

Cheers for the help so far Digital Sonata
