newly installed ubuntu 8.10 cannot connect to the internet

Asked by willd

Hi.

I have an HP Pavilion Desktop running a WinXP Media Center.

I have just installed ubuntu 8.10 desktop via wubi in the WinXP. The wubi install seems complete except that the installed ubuntu 8.10 is unable to connect to the internet. I believe It is currently timing out. Two days ago the network manager in the ubuntu 8.10 cannot establish a connection with the wired eth0.

The network controllers in the HP Pav are:
o Intel Corporation 82562V 10/100 Network Connection (rev 02)
o Atheros Communications Inc. AR5413 802.11abg NIC (rev 01)

The HP Pav is connected to an ADSL Router (Billion) with VOIP capabilities.

I have another PC running Ubuntu 8.04. It is connected to the same ADSL router that the HP Pav is connected to. Because of this I can compare the output from the Network Tools of each PC.

To summarize the results:

o The Network Tools' device tab of ubuntu 8.10, shows a very large number of reception errors. The equivalent information from the Ubuntu 8.04 shows no reception errors.

o Pinging an external address is very slow in ubuntu 8.10 compared to the 8.04 ubuntu.

o Sometimes the ubuntu 8.10 fails to complete a traceroute successfully, when given a proper domain name (eg. www.google.com). It seems to do better with just ip addresses. The ubuntu 8.04 has no problem with any of these.

I am beginning to think that I may have a "broken" network controller in the ubuntu 8.10. But I believe I need to establish that. I also need to explain why the WinXP in the HP Pav, with the Ubunt 8.10 inside it, can access the internet.

Hence, I am not fully convinced that my "broken" hardware hypothesis is correct.

I am attaching the results of the hardware test from ubuntu 8.10.

This sounds worthy of being made into a bug. You have provided a lot of information.

I know nothing about WUBI. I'm assuming you can get to /var/log and look for anything noteworthy in the logs. What about any of the WUBI's network settings?

Hi. Thank you for your response to my post. And sorry I did not not respond
sooner. What happened was that I lost my second Ubuntu in trying to
replicate the WUBI 8.10 install. And then I encountered a few more problems
after that. My priorities have changed: I have to recover this system first.

I will get back to you as soon as I clear up this mess.

Please try to disable ipv6

Please use this official method to disable ipv6 https://help.ubuntu.com/community/WebBrowsingSlowIPv6IPv4

In short, open Applications → Accessories → Terminal and type

sudo sh -c 'echo blacklist ipv6 >> /etc/modprobe.d/blacklist.local'

give your user password when requested, you don't see nothing when you type it, then press enter.

The above command appends a line to the local blacklist configuration. The file will be created if it does not exist.

To restart your computer, type:

sudo reboot

Hope this helps

I suggest you to install Ubuntu NOT using Wubi.

If you have installed Ubuntu via Wubi please uninstall it read http://wubi-installer.org/faq.php

Installing Ubuntu using Wubi make Ubuntu less robust and all problems that you will have to Windows can be affect your Ubuntu partition file.

I strongly suggest you to install Ubuntu+Windows in dual mode creating a real Ubuntu ext3 partition.
In this mode you can use Ubuntu and Windows ad usual and then using installed Ubuntu you can save or repair damaged (due viruses or other issue) Windows partitions data.

- Here the steps to install Ubuntu 8.04.1 https://help.ubuntu.com/community/GraphicalInstall (pretty the same for Ubuntu 8.10)

Is very easy to install, if you need info please ask.

Thank you

Hi. Many thanks to those who responded to my post.

I believe we can close this problem now. New to this, I am not exactly sure
how to close off a post.

I have decided to abandon the wubi install of ubuntu 8.10. Instead I decided
to install ubuntu 8.04 as a dual boot with the winxp. That went well.
marcobra's suggestion to disable the ipv6 did the trick with the slow and
"cranky" internet connection. I also decided to switch off the autoneg
feature, and slow the speed down. Things are working well now with my
internet connection

You've been all a great help.

I thank you all very much
