Can't connect to wireless after 11.10 upgrade

[Bubb2112]

Yes, it's there. I only installed one ubuntu, so the boot menu doesn't load, it just loads my only instance of ubuntu 11.10.

How do I boot from the older kernel?

Hold down the "shift key" while machine is booting will bring up the grub boot menu.
It defaults to bypass the menu when only one install.

You can download this app to select kernel I do believe, with or in graphics to make new kernel selected now default:

sudo apt-get install startupmanager

rick@rick:~$ aptitude show startupmanager

GavinRick4,

That did it. I appreciate your help, I would have never figured that one out myself. You're a hell of an ubuntu addict, lol.

Is the old kernel going to cause other problems, or will it just be ok until the next distribution upgrade?

I am happy it worked out for you. You will see a post in
these Forums where the "iwlagn" driver problem will be worked out and you can upgrade
your kernel. Not all Intel cards using "iwlagn" is having the problem but will be figured out
eventually. Here is link of kernels when needed. Enjoy your Ubuntu Bubb2112.

Hi pro.gangster, rihgt now the only way that we know for sure to get this card working is to downgrade your kernel, you can follow the directions in post 42 to do that if you want too.
Thank you

I couldn't understand the process, because I'm a new ubuntu user

Is downgrading the kernel,downgrade my ubuntu too?

[wildmanne39]

Hi pro.gangster, yes that is the only choice that we now of at this time,garvinrick4 can help you with that if needed, I am not on much right now I am helping right some documentation for the forum.

No, it does not downgrade your ubuntu too.

Thank yougarvinrick4
I am not quite awake yet.

Run this in a terminal to tell if you have 32 or 64 bit.

uname -a

If it says this below in the line then you have 64 bit any thing else you have 32 bit
x86_64 x86_64
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38-natty/
Now going to link above you will see in bottom 5 lines two that say 32 bit and 2 that say 64 bit.
Take the 2 that are yours in 64 or 32 bit and the 1 that says all.deb and that is 3 of them to download.
all.deb ( for both 32 or 64 bit)
headers (32 or 64 bit)
image (32 or 64 bit)
Now Download them the 3 of them.
Click on them in same order and they will install through Ubuntu software center and give you the 2.6.38 kernel to choose from when you boot at the menu.
If you do not get a menu at boot it is because you only have 1 install, it takes 2 installs to show the boot menu screen (by default). So to see the boot menu entry screen hold down the shift key
at boot and will show you screen to choose 2.6.38 kernel.
If you want to make it permanent install this application and choose the kernel for it and will always open in 2.6.38 kernel.

sudo apt-get install startupmanager

Is there a bug on launchpad or any other page that we can follow to check whether they have solved the issue? I solved my problems by reverting to 11.04 as I had other issues with Oniric anyway, but it would be nice to know when it's safe to move forward. Thanks anyway!

Is not on all machines using iwlagn driver with Intel Network card, I have the same driver and works fine. No one has found common denominator as of yet. Might be smart to look around launchpad.net bugs again to see if problem with kernel and driver has been discovered. Get back here and give report if you can. Have a nice day.

i have the same issue here with Intel Corporation PRO/Wireless 3945ABG card and it sometimes connect and disconnect after while i have usb wireless adapter which i am using now but it also has problem with this new kernel its really sucks i use tp-link TL-WN722NC, so i think 11.10 have serious issue with networking. since i have another 2 friends who has same issue and with different hardware. i think ubuntu developers should seriously look in this. please help us soon i like the new ubuntu but need to go back to 10.4 now.
