I am not quite sure I understand what you are wanting to do? Are you wanting to connect to a wireless network that you just created? or are you just not being to connect to any network at all?

I want to create wireless network, so that other notebook can connect to it by wireless.

I may be wrong, but I am not sure that in ubuntu you can create a wireless network from your own laptop and then share it with other computers. I have never heard of that being done on ubuntu before just on Macs. I think it is because they have something called the Mac Airport built-in to their laptops; im just speculating here though, I do not know for sure.

To create a wireless network you will need a wireless router in your home connected to your internet connection (DSL or cable modem usually). From there you can share with whomever you want.


To answer your last post, ubuntu 8.10 comes with kernel 2.6.27.7 and if you have the lastest update your 8.10 setup should have 2.6.27.9. I do not think updating to ubuntu 9.04 will help your problem at all seeing as it in its alpha state and more than likely unstable with little driver support.

I stand corrected. I found this thread here that will show you how to setup such a connection from your laptop. Go here (http://ubuntuforums.org/showthread.php?t=398771) to read it: http://ubuntuforums.org/showthread.php?t=398771

Basically you need to left click on the network manager applet in the top right of your screen. From there go down to "Create Wireless network" and it will be created.

Though just creating the network and sharing it is not enough. Now you have to setup a dhcp server on your laptop. (I personally have no experience setting up a dhcp server on linux; I found an article here (http://www.linuxtopia.org/online_books/linux_beginner_books/unofficial_ubuntu_starter_guide/index_192.html) that explains how to do that.)

From there you other computers should be able to connect. Post back here if you have any issues and I will try to help.
