During installation, I input a simple password like what I always used.
After finished update, when I wanted to change password back, it said the new password is alike with the old one.
To solve this problem, just give root a password, then use root to change user’s password.
1. sudo passwd root
2. su -
3. passwd xxxx
4. exit
After Ubuntu 8.04 updating to Kernel 2.6.24-19-generic, my wireless card is lost and WLAN configuration is invalid.
It spent my 4 hours to solve this problem, the following is summary:
1. Install b43-fwcutter,
sudo apt-get install b43-fwcutter
2. Run b43-fwcutter
sudo /usr/share/b43-fwcutter/install_bcm43xx_firmware.sh
3.rmmod
rmmod ndiswrapper
rmmod ssb
rmmod b43
4.modprobe
modprobe ndiswrapper
modprobe ssb
modprobe b43
5. To check wlan0, OK
ifconfig -a
6. Config WLAN
Ubuntu Status bar, left click “Network”, Mannual configuration, unlock, Wireless connection, Properties, WPA, DHCP or IP (depend on your AP), disable LAN, save as a new network location.
Before these steps,
I have updated ndiswrapper to V1.9, both common and util, and found no ndiswrapper in /usr/sbin, so make a link(ln -s).
Reinstall DELL Wireless bcmw15.inf
The posts I have read,

It works, so I post this article by WLAN.
Why Microsoft Windows hasn’t the function like “grep”? When analysing application logs, the question will always be asked.
Fortunately, we can find some tools, such as AstroGrep(opensource freeware), which can do same thing under Windows just like Unix or Linux.
The following content is copied from: http://astrogrep.sourceforge.net
“AstroGrep is a Microsoft Windows grep utility. Grep is a UNIX command-line program which searches within files for keywords. AstroGrep supports regular expressions, versatile printing options, stores most recently used paths and has a “context” feature which is very nice for looking at source code.”
AstroGrep includes the following features
- Regular expressions
- Concurrent multiple file types
- Recursive directory searching
- A “context” feature that selects the lines above and below your search expression
- Most Recently Used list for search paths
- Somewhat versatile printing options
- Double click to open file with editor of your choice
- Store Most Recently Used file names and search expressions
- Match Whole Word Only
- Syntax highlighing
- Free of charge and Open Source
I like Filezilla, because it has both Windows version and Linux version. FTP sites can Imported/Exported between the two OS platform. The XML file exported can be modified by a text editor, such as Notepad.exe or gedit.
