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 :???:
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
This is all I got using LXTerminal,

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. :confused:
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.zip
This 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 )

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 issueQuote:
Hi, 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.cfg
Place 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=localtime
Save 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.
I haven't tested if the Wifi still works with a reboot though.Quote:

Whats happened now is the old comp I have been testing this on had a moment and wiped the USB stick.
So I reloaded the stick again but now it won't boot? Reformatted a second time and reloaded but still no go?? Boot order is still set for USB 1st.
Tried on another comp with boot order USB 1st and it didn't work on that either??
Ok, I have got this thing going again, but after reboot the Wifi stops working, so I need to get this cheat code working.
So im back to this step,

How did you create your bootable USB stick?
What happens if you issueandCode:find /mnt-system -iname syslinux.cfg
Code:find /mnt-system -iname menu.lst
Those two commands didn't do anything.
Im using unetbootin to create.
You will find a file called syslinux.cfg in the root directory of your bootable USB stick. If you use Windows open this file with wordpad. If you are running Knopix use Leafpad text editor.
Search for a section with 'menu label knoppix' like the following:Move the cursor to end of the line starting with 'append' and add your cheat code there. In my case the new line looks likeCode:label ubnentry2
menu label knoppix
kernel /boot/isolinux/linux
append initrd=/boot/isolinux/minirt.gz ramdisk_size=100000 lang=de apm=power-off nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime
Save the file and reboot.Code:append initrd=/boot/isolinux/minirt.gz ramdisk_size=100000 lang=de apm=power-off nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime modprobe.blacklist=rtl8192cu
Tried that but still no go?
Code:label ubnentry2
menu label knoppix
kernel /boot/isolinux/linux
append initrd=/boot/isolinux/minirt.gz ramdisk_size=100000 lang=en apm=power-off nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime modprobe.blacklist=rtl8192cu
I thought you would choose the menu entry 'knoppix' from the menu at boot time, but if you want to use 'Default' (the first entry in the boot menu) you have to edit the 'append' line of the 'Default' section. On my system I have gotCode:label unetbootindefault
menu label Default
kernel /ubnkern
append initrd=/ubninit ramdisk_size=100000 lang=de apm=power-off nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime modprobe.blacklist=rtl8192cu
Yes that's got it going now. :)
I just use 'default' so I only have to hit enter to boot. :)
Ahh now I see now how it works, so if I want to use Knoppix64 in the 'boot menu' at start up with Wifi, I would have to add it to that line as well.
Thanks so much klaus2008 for your help to get this working.
