8.04 connection troubles

[hwttdz]

I just upgraded (reformatted and clean installed) 8.04. I now have 0 internet connection. I don't even know where to start with getting things going. I have tried dhcp, and choosing my own ip address (just typed in what I got from window's ipconfig) and whatever the other option there is (I'm typing from windows now so I can't look). In network tools it seems to be sending pings from eth0, at least the bytes sent increments when I ping something. I've entered the open dns servers as my dns servers (I deleted an empty dns server there). I don't know what to do. Any help would be appreciated. Thank you.

[superprash2003]

are you getting an ip from your router? type ifconfig and check if you are getting an ip.. if possible post the results here

[hwttdz]

The results of ifconfig in ubuntu are:

Try blacklisting the IPv6 router by typing


sudo nautilas

Once nautilas opens go to etc/modprobe.d add this to the file


blacklist ipv6

In the same folder "etc" go the the aliases file and press [space] once next to IPv6 add this


disable=true

I installed 8.04 on my grandpas computer and he had a sis191 ehternet adapter this is how I got it to work. It wasn't using ipv4 on its own.

[viceroy]

After you do all that then take your connection down and back up with this


sudo ifdown eth0

sudo ifup eth0

and then do this


sudo dhclient eth0

don't forget to enable dhcp.

[hwttdz]

Do I enable DHCP in a place other than network manager?

[viceroy]

network manager is fine

[hwttdz]

Still no luck.

you don't happen to be using wireless do you?

[hwttdz]

Nope, when I post I'm posting from windows of a dual boot.

[viceroy]

Can you post the results to this for me

I'd love to update my drivers, but it's harder without a connection.

[superprash2003]

have you tried manually entering the ip address in the network manager?

[hwttdz]

Yup, I did that copying the address that windows had assigned me and that seems to work there.

[superprash2003]

have you tried pinging the router when it is manually assigned?assign ip manually and then post ifconfig results and also type ping 192.168.1.1 if 192.168.1.1 is your router ip and post results here

[GreatSunJester]

Did a full install on my crappy Compaq laptop (using a generic Atheros wireless and the default HP wired). Everything installed perfectly but I ended up with the same issue you report.
Even looking at my router (Buffalo with tomato firmware) I can see both devices being assigned IPs but I could do nothing with the connections. Restarting networking and even the whole machine never helped.
Until I specified my DNS -- both connections immediately began working. For some reason the networking in 8.04 is not getting all the info my router was providing. Vista and XP get it correctly. I have not tried this machine on other networks yet to see if it is an issue with my router or with the networking itself.

[hwttdz]

As I have already stated I have been using open dns dns servers, entered into the dns servers, I have also tried using a manually assigned ip address.

What exactly are you looking from ifconfig, as I would like to provide just that information using a second computer rather that having to reboot just to copy and paste.

[josel777]

I am having the same problem. Updated from Gutsy to Hardy and have no internet connection (wired or wireless). I reinstalled my wireless drivers and now my wireless light is blue, yet when I try connecting to my router I can't get an IP address.

This is incredibly frustrating.

Update, I can connect to the Internet as long as I manually enter the IP.

[al-fil]

Same thing here. Updated from Gutsy 7.10 to hardy 8.04 and no internet. When I first installed Gutsy two months ago I had to do nothing to get my wired connection running-
Anyway, I've tried going through connection manager but had no luck. I'm using my windows laptop (yuck!](*,)) and I can't find a decent procedure to get my connection back. I've read other posts that talk about b43-fwcutter and broadcom but I've no idea what those are for.. Please help me get back to my ubuntu box!

Same here, the advice given is a repeat of the advice given to others with same/similar problems.

Here is my problem reposted: hope this helps someone to get to the root of problem.

I have just installed kubuntu hardy and now have issues connecting to internet.

Konqueror displays "ubuntuforums.org contacted. waiting for reply"

I can ping above web address and ifconfig shows:

knetworkmanager shows that I am receiving and transmitting data.

On occasions konqueror progress bar shows 75% and then freezes but no info is shown on screen.

Any one got an idea whats going on

[joes_meat]

I am having this problem too.

I've tried booting with acpi=noirq on a recommendation with no luck (made the system run really slowly too.)

I've tried with a Via Rhine VT6107 and another generic Ethernet card. Exactly the same results.

On roaming and DHCP, it gets a private ip address: 169.x.x.x
On static, I use 192.168.1.2, it can ping itself but not the router or internet.

Worked fine in Dapper, Edgy, Feisty, and Gutsy.

[hwttdz]

I can get a connection if at the prompt I call

sudo modprobe -r forcedeth
sudo modprobe forcedeth msi=0 msix=0
sudo /etc/init.d/networking restart

Right now I am unable to get this to work at startup. So I am still looking for a way to do that.

[joes_meat]

Add those commands to bootup.

[hwttdz]

Can you please elaborate?

[al-fil]

Adding to boot up is not working... But in case you want to try, see post #57 by sam_delta

[josel777]

For those with Broadcom cards, this worked for me:

http://ubuntuforums.org/showthread.php?t=766560

[v.s]

I don't know if anyone else has this problem, but anyway, here it goes:

When I leave the network setting at roaming, it recognizes a connection, but I get no IP address. Then, when I change it to DHCP, it doesn't recognize a connection, at all.

I've already blacklisted IPv6, by the way.

[Dutchmaster]

All these attempts to solve this require a Ph.D in command line ... :mad:. Repeatedly they're not working. It's obviously a major showkiller bug for a user. I suggest the team prioritize coming up with a more automated fix if you're ever going to hope to attract Windows users.

I'll just wait for Linux Mint Elyssa - they'll fix it.

This does not happen in other distros - not even one - of the scores of distros I've tried.

found my solution!

Using a belkin Wirless G usb network adapter:

1. no problem with the right driver.
2. able to get wireless by entering commands in the terminal
3. I have my essid hidden
4. I use WEP 128 bit encryption
5. I followed the instructions in this thread, helpful, but no connection.

http://ubuntuforums.org/showthread.php?t=571188

I tried for hours using the instructions on that thread. It was helpful towards my final
solution. Using the Network manager just kept getting me into dead ends.


$ sudo gedit /etc/rc.local showed this:


#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0
I added this to the rc.local:


ifconfig eth0 down
ifconfig eth1 down
dhclient -r eth1
ifconfig eth1 up
iwconfig eth1 essid "linksys"
iwconfig eth1 encryption on
iwconfig eth1 key 1a2b3c4d5e ASCII
dhclient eth1

rebooted and still nothing. I wondered why that would not get my a connection on boot. I got desperate. I remembered my simple bin bash command. I commented out #!/bin/sh -e, added #!/bin/bash. saved rc.local and rebooted. And I had an internet connection on boot. #!/bin/sh -e should have worked, but not for me.

Make sure you don't have any driver conflicts. I Installed rt73 rt 2500 with ndiswrapper, and it did nothing. I finally deleted rt73,rt2500, and ndiswrapper. It seems that 8.04 and 7.10 have the drivers native that are compatible with this Belkin.

Try entering first from the command line to see if you can get a connection:

ifconfig eth1 down
sudo dhclient -r eth1
sudo ifconfig eth1 up
sudo iwconfig eth1 essid "your routername"
sudo iwconfig eth1 encryption on #I don't know if you need this
sudo iwconfig eth1 key 1a2b3c4d5e ASCII
sudo dhclient eth1

Yes, it should be easier than this!

[hwttdz]

I know I'm awful for not sharing earlier, but I found (and now refound a solution to this).

Add the following line to /etc/modprobe.d/options

options forcedeth msi=0 msix=0
Then rebuild initramfs like this

sudo update-initramfs -u

If you read down further I see msi=1, which may work for some, but I have not tested it.
