ubuntu 10.10 64 bit - wired connection ok in live CD, not after full install


Thanks to anyone willing to help me. Did search, tried installing drivers, no luck.

I'm a Linux newb, but have successfully installed and run (all 32 bit) Mandrake, Ubuntu, Fedora and Puppy Linux on other machines. I know just enough to be dangerous but I found I like Ubuntu the most so...

I just built up a computer and want to run Windows 7 Pro 64 bit and Ubuntu 10.10 64 bit. I partitioned the drive in 2 equal sections, installed Windows 7. When I boot in the Ubuntu CD following POST, I originally had some very weird issues with the mouse acting erratic - jumping around and creating windows at random - almost like the scrolling action was a command to open a window.

Frustrated, I decided to try Fedora 14, 64 bit. I did not have the mouse issues, so I installed it to the HD (including swap partition). However, I could never figure out how to get the network adapter to work following full install.

Yesterday, I decided to give Ubuntu 10.10 64bit another try. I booted, kicked the tires again in Live CD, surfed the web - all worked well. So. I decided to install it over the Fedora, which I did.

Now, I'm in the same situation as Fedora - it says eth0 and eth1 are disconnected. eth0 is connected, eth1 is not. WTF?

I've never had this issue with 32 bit versions (yes, I realize I should probably try 32 bit) but I just can't get over the fact everything works in Live mode, but I can't get an internet connection when installed.

Wouldn't it install the appropriate driver? Most posts when I searched refer to wireless issues; not sure if same issue with wired. I did download, unpack and install the Realtek linux driver, but still no go.

Intel Core i7 870
4GB (low, I know)
Asus 1156 P7P55 WS Supercomputer mobo w/integrated dual ethernet
EVGA geForce GTX460 768MB VC
Seagate Barracuda 1TB 32mb cache 7200rpm
OCZ ModXStream-Pro 600w PS
ANTEC 300 Case
Logitech Wireless M570 trackball
$3 keyboard (working on a real one)...

Thanks,
Troy

I suggest checking your network connection settings. I've seen this kind of problem once or twice before, and the solution was to change IPv6 settings. I don't know why it works on the live cd but not on an installed system.

To change IPv6 settings in Ubuntu: Right-click on the Network Manager icon in the upper right of the screen. This will bring up a menu. From the menu, click on "Edit connections". In the window that pops up, make sure you are on the "Wired" tab and select the "Auto eth0" connection, and click the "Edit" button. Click the IPv6 tab. If the "Method" is set to Automatic, the try setting it to Ignore; if it is set to Ignore then try setting it to Automatic. Then click on Apply.

everest - thanks for the post. I am running 10.10 64 bit from the CD at this very moment. No issues like I said. The network settings are all standard (connect automatically, no 802.1x security, IPv4 method on Automatic (DHCP) and IPv6 method on IGNORE.

I went into the installed version earlier, changed some settings with no net gain. And my 32 bit download failed, so I'll try that one more time before giving up for a while.

Thanks,
Z

Hi,

I downloaded and installed ubuntu 10.10 today, using the windows installer, to a clean partition and I have the same problem. The network setting are exactly the same. I tried deleting the connection and setting up a new one, even tried reinstalling the whole thing but it still did not work.

FWIW, I ran uname -r in various scenarios. All came back 2.6.35-22-generic

This goes for 10.10 64bit live, 10.10 64 bit install and 10.10 32bit live. The install failed on two machines for 32bit, so I scrapped it and reinstalled 64 bit. I may try Mandrake or another distro, but if it continues I'll just take my lumps and go 7 across the board.

I also ran lsmod and had solid page of stuff to look at for each version. Nothing obvious, but I didn't go line by line yet.

Thanks in advance for any advice.

My problem is solved. Not sure exactly how, but I did the following:

After re-installing 10.10 onto the partition, I booted into it and had the same issues. I then deleted both autoEth0 and autoEth1 and added a new wired connection. However, that seemed to do no good. So then I thought I should poke around in the BIOS.

Once in BIOS, I didn't find any obvious clues as to what to do. But I did enable the "check LAN cable on POST".

Next boot up, I have internet.

Neither option seemed to make sense, but I'm surfing now. And up on 1440x900 resolution since I could download the graphics driver.

FWIW.
