udev[286]: renamed network interface eth0 to eth0-eth2 -> DISABLED Wireless Network controller [0280]: Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter [8086:1043] (rev 04) can detect but cannot connect to wireless access points using Dell Latitude D600 in Ubuntu 11.04 and when using kernel 2.6.38-xx
Basically the wifi on my Dell D600 laptop works fine if I stick with kernel 2.6.35-28. But it won't work with recent versions such as 2.6.38-8 or 2.6.38-10. The network manager icon in Gnome is displayed as an empty pie segment (i.e. no curved signal bars). There are no wifi access points listed when I click on this icon.
Running:-
iwlist {interface} scan
...returns information about local access points including my own. So I think hardware & ipw2100 driver are OK.

Hi,
Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).
In order to gather essential troubleshooting information about your wireless card, please follow this procedure:
Step 1:
If you are using the Gnome interface, open the Terminal console via "Applications-
If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.
So the methods in Unity are:
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal
Step 2: Please copy-paste the following command from https:/
Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!
sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/
Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.
Step 4: Please also clarify if you installed Ubuntu to the harddisk and are running from a harddisk install OR if you are only testing Ubuntu in a LiveCD session.
Regards,
Mark

The following output in your dmesg log is very strange and may be causing issues here:
udev[286]: renamed network interface eth0 to eth0-eth2
I can only suggest the following action steps at the moment:
In your wireless router settings (not on your pc, but on the router itself), change the wireless transmission channel to channel 1 in order to avoid wireless interference from the other wireless access points.
Also make sure that the SSID name of your wireless access point does not contain any spaces in it.
Copy-paste the following command into the Linux Terminal:
sudo apt-get update && sudo apt-get install wicd
Then reboot and retest wireless using wicd network manager.
