no internet connection (wifi+ethernet doesn't work) (iwl 5100)

same here, while trying to test karmic alpha 5.
On a toshiba satellite P300-1HO, wifi doesn't work. and neither does wired ethernet.

ifconfig just shows the loopback device.

And moreover the wired ethernet device doesn't show up either, but I don't see related messages in the logs. (But I have to investigate further.)

it's with the x64 kernel.

works fine with jaunty, kernel 2.6.28-15.

@Andy

when this fix will be committed in kernel karmic?

Hello, we have another, but SIGNED solution here:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=15b812f1d0a5ca8f5efe7f5882f468af10682ca8

Signed-off-by: Yinghai Lu <email address hidden>
Signed-off-by: Linus Torvalds <email address hidden>

This is solution without revert previsous Yinghai Lus patch (it create this problem)

Both solutions (revert problematic patch or this commint without revert) works for me. But this is signed by Linus.

When this fix will be committed in kernel karmic?

i hope that this fix will be in ubuntu RC or final edition...

This should be critical for Karmic. It affects many laptops (2 or three models of acers), has a quick fix, and also kills at least both ethernet and wifi for me, making a post-release fix very difficult.

Both fixes are working for me, btw.

I've got a Acer Extensa 7630G
07:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100
09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5764M Gigabit Ethernet PCIe (rev 10)

I upgraded from Jaunty to Karmic yesterday. Same problem here. (64bit)
Same problem on a LiveCD (same kernel).

Also tried http://people.canonical.com/~apw/lp386468-karmic/ and it's working much better!

I have the same problems with Intel 5100 wireless and Marvel Yukon ethernet.

Any idea when Karmic will receive an update for this? My only alternatives at the moment are using a usb wireless adapter or going back to using Windows Vista.

it's incredible that there is code fix and karmis has been released with this important bug unsolved...it's incredible!

agreed, I am very disappointed with this. This is a critical bug that affects a large number of users. This should have made it into the final version of what is otherwise a fairly good release.

Couldn't agree more. Several laptop models with a fresh karmic install
will now be without internet access. And all users who don't find the
acpi=off workaround will be having some trouble upgrading their systems.

HI guys

Same issue for Toshiba satellite pro U400 laptop.
Will try acpi=off now.

Probably same issue on final version Kubuntu 9.10 Karmic - notebook HP Probook 4510s. I installed
http://people.canonical.com/~apw/lp386468-karmic/linux-image-2.6.31-12-generic_2.6.31-12.41lp386468apw1_amd64.deb
from http://people.canonical.com/~apw/lp386468-karmic/ but same problem after reboot and selection this kernel to start - it hangs on startup. Do I need to use the patch or just install the package with kernel?

Same issue here on Acer Aspire 7730G. Network only available with acpi=off. Quick implementation of available bugfix would be really helpful! (Why is the bug report's importance set to "low" only?)

I am not sure if this information is useful. I have the same problem (2.6.31-14-generic). wlan did not work on my Dell Vostro 1520 with a hardware wlan switch.
In my case It seems to be similar to
https://bugs.launchpad.net/ubuntu/karmic/+source/linux/+bug/395358

When I switch my wlan on ( killswitch=off) before I boot, wlan will not work. checked rfkill list:

>rfkill list
0: dell-wifi: Wireless LAN
 Soft blocked: no
 Hard blocked: yes
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no

Next I switch the wlan off - >

>rfkill list
0: dell-wifi: Wireless LAN
 Soft blocked: no
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes

So this seems to be wrong.
But when I switch wlan off ( killswitch=on) before I boot with I can enable the wifi adapter after login and wlan works perfect.
And it also works if I boot with older kernel 2.6.28-16-generic.

So for my understanding the default setting of the rfkillswitch in kernel 2.6.31-14 seems to be wrong

Same problem here (Acer Aspire 6930, Intel WiFi 5100). Please increase the priority of this bug!!! It is already known since August!

I have the problem, too (Acer Travelmate 7730 iwlagn and tg3 driver). The workaround with acpi=off is not really usefull when using a notebook. I hope a fix will come soon, actually i won't use such a OS for working.

Here is all dmesg output

I had the same issue, I have an Acer Aspire 6930G.

Karmic didn't even start installing with the live cd without acpi=off, I guess it needs net connection to get along.

I have tested both 32 and 64 bit fixed kernels from http://people.canonical.com/~apw/lp386468-karmic/ and they work just fine.

I second importance of this bug being raised please? And hopefully resolving in the next update?

Same bug here Acer Aspire 6930. This is my wifes laptop. She hates Windows with a passion, but this bug has driven her back as it renders her laptop unusable.

Could someone please explain the reasoning behind giving this bug low priority when it renders entire series of laptops close to unusable and there already is a confirmed fix for it? I really do not understand this...

Same here on two laptops. Wifi is just fine, but wired network reaches to the PC's and printers in my home-network, but no internet thru the gateway. Using the older kernel solves that problem.

BTW, had to reconfigure GRUB in order to boot from /dev/sda1 instead from the UUID because it seems that UDEV doesn't recognise /dev/disk/by-uuid at all. Kept dropping to to BusyBox!

@steff: I am sorry but it must be different error. I this case, network adapter still uninitialized and not working absolutely. It not depend to local or internet.

Ok there seems to be an attempt upstream to resolve the issues introduced by the fix reverted in the previous test patch. I have pulled this fix back to the Karmic kernel and produced some test kernels. If those who are affected by this could test these kernels and report back here. Thanks! The kernels are at the URL below:

    http://people.canonical.com/~apw/lp418933-karmic/

This test version (http://people.canonical.com/~apw/lp418933-karmic/ )
SOLVE problem on Acer Extensa 5635G

For others, this solution not revert problematic patch, but it is same Linus signed patch for 2.6.32. See
http://people.canonical.com/~apw/lp418933-karmic/0002-pci-increase-alignment-to-make-more-space-for-hidden.patch

Thanks for the update Andy.

I tried the 64 bit kernel from http://people.canonical.com/~apw/lp418933-karmic/ and it works fine on my Acer Aspire 6930G. Wired / wireless both functional.

Hope this fix becomes mainstream in next kernel update from Karmic
=)

Tried the kernel from http://people.canonical.com/~apw/lp418933-karmic/.

Worked great! Solved my problems.

I tried the 64 bit kernel from http://people.canonical.com/~apw/lp418933-karmic/ and it works fine on my Acer Aspire 6930G.

Thanks all for the testing feedback. This fix is now in 2.6.31.6 stable updates which is being reviewed for inclusion. I will add this testing result to that.

I tried the 2.6.31-15 kernel from
http://people.canonical.com/~apw/lp418933-karmic/
But this did not solve the wifi problem on my vostro 1520. There is still the killswitch in the wrong state after boot.
Can anybody give me a feedback if my posting (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/418933/comments/94) should be related to the new kernel (2.6.31-15)?

When I test the rfkill list it shows still wrong result if the hardware WLAN switch is on before booting:

rfkill list
0: dell-wifi: Wireless LAN
 Soft blocked: no
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes

I need to boot with deactivated wlan to be able to activate wlan after laptop was booted.

@rsoika

There are several wlan "killswitch" problems reported as a bugs.
I think that might be your problem.

This bug is about no internet connection at all :
No wireless , No wired connection.

Ok testing confirms that this is the same bug as bug #407824, which also confirms the same fix as resolving the issue there. I am therefore nominating the older one as the tracking bug for this issue with iwl 5100 and ethernet not working.
