Hi!
You did not write enough about your USB WLAN adapter. I think you should plug in your USB wireless adapter and open an LXTerminal. Then issue the commandand tell us all about the wireless adapter.Code:lsusb
Hi, I have Knoppix 7.0.5 DVD on USB stick, and USB Wireless N 802.11n/g/b adapter.
Knoppix's can see my wireless network, the box comes up to put the wifi pass in then tries to connect for a while, but the box comes back up to connect again but never connects.
I have the CD with the drivers and there is a folder on there with drivers for Linux if that's of any use??
Also I am new to Linux based op systems

It is a well known bug. Look at https://bugs.launchpad.net/ubuntu/+s...x/+bug/1030858
I use an wireless LAN adapter by Edimax with the same chipset. In post #73 of the thread mentioned above you will find a link for the latest Linux driver. If you are curious you can install this driver and boot up your system using the additional cheat code 'modprobe.blacklist=rtl8192cu'.
Ok, I have got the updated drivers for this.
So how do I go about installing this driver??
And also the "additional cheat code 'modprobe.blacklist=rtl8192cu", how do I boot up the system using that?? Where do I type that??
Like I said, I am new to Linux based op systems.
In the following I suppose you downloaded the driver archive file to you desktop.
You have to open an LXTerminal, change to the directory with the driver archive file and unzip the file. IssueThe files will be extracted to a new subdirectory. IssueCode:cd /home/knoppix/Desktop unzip RTL8192xC_USB_linux_v3.4.4_4749.20121105.zipThis will compile and install the new driver files.Code:cd RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105 sudo bash install.sh
Now you can edit GRUB's configuration file. IssueThis will load the configuration file into the leafpad text editor. Search for the line starting with 'kernel /boot/vmlinuz' and append the cheat code modprobe.blacklist=rtl8192cu at the end of the line. Save the file and close leafpad text editor.Code:sudo leafpad /boot/grub/menu.lst
The you should be ready to reboot your system. After reboot connect your USB wireless LAN adapter and try connecting to your wireless network.
I have installed the driver but im not sure where to put the "modprobe.blacklist=rtl8192cu"
Here is the menu.lst file,
# menu.lst - See: grub( 8 ), info grub, update-grub( 8 )

## default num

# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your

I see I made a little mistake. I read your first post again and foundYou are using syslinux as bootloader. Thus you have to edit /mnt-system/boot/syslinux/syslinux.cfg and append the cheat code at the right place. Open an LXTerminal and issueHi, I have Knoppix 7.0.5 DVD on USB stick, and USB Wireless N 802.11n/g/b adapter.Search for a section that looks likeCode:sudo leafpad /mnt-system/boot/syslinux/syslinux.cfgPlace the cursor at the end of the line that starts with 'APPEND' and add the cheat code.Code:LABEL knoppix KERNEL linux APPEND ramdisk_size=100000 lang=de apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtimeSave the file and close the text editor. Then reboot the system. Of course the cheat code 'lang=de' could be 'lang=en' if you are using english language.Code:APPEND ramdisk_size=100000 lang=de apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime modprobe.blacklist=rtl8192cu

When I open "sudo leafpad /mnt-system/boot/syslinux/syslinux.cfg" there is nothing in there, its just a empty file??
Something happened to my USB Knoppix where Leafpad would not open anymore and also the text files wouldn't open anymore either.
So I reloaded the USB stick with a fresh install of Knoppix , reinstalled the new Wifi driver, and now Wifi IS working with no cheat code??
Thanks for your help with this klaus2008.
