Wireless How to for Knoppix 5.3.1
Dear all,
Some time ago, I promised an user (I forgot who) to try to find a way to use wireless connection on Knoppix 5.3.1. He mentioned that if we can make wireless working on the 5.3.1 may help some blind people. So I am very happy to have it done.
It took me a while to download the DVD and have it working.
I spent the past weekend on 3 network cards on three machines and have them wireless connect to the network successfully.
I put up all the three cases on the FAQ page so you can take a look at it if you are interested.
Case 1, wireless card recognized by Knoppix 5.3.1 : see FAQ question 11.
Case 2, wireless card not recognized by Knoppix 5.3.1 : see FAQ question 12.
Case 3, Broadcom B43 wireless card on Dell Latitude D610 and D600. Wrong bcm43xx driver loaded plus missing firmware : see FAQ question 13.

Chip Ling,
Glad that you have prepared a howto procedure for beginners to work with.
Though I have followed this wireless LAN step-by-step guide (case 1) for a D-Link GWL122 adapter (802.11g) installed on a desktop PC running Knoppix 5.3.1 (HDD version) intended to connect to a D-link 724+ (with encryption OFF) wireless router but I failed to bring the wireless LAN up and running.
I first booted Knoppix 5.3.1 without the D-Link DWL122 plugged into the usb slot. I plugged the adapter into its place when I am about to issue the iwconfig and ifconfig commands. Appended is the test log:
==juliantchan@KNX-Host:~$ su
==Password:

==root@KNX-Host:/home/juliantchan# pump -i wlan0

==failed to connect to localhost:bootpc: Network is unreachable
==There might be another pump running!
==Operation failed.
==root@KNX-Host:/home/juliantchan# ifconfig
==root@KNX-Host:/home/juliantchan#
On a second try, I have have put the D-link GWL122 adapter into the usb slot before the booting.
Result is the same except pump command only returns "Operation" failed (without "There might..............).
On a third try, I have been consistently and successfully bringing the wireless LAN up with the same hardware combination except using Knoppix the latest Knoppix (version 6.0.1 CD) - even with WPA encryption ON.
Lastly, I failed to bring the Wireless LAN up with a PROLINK WN2200 usb draft 802.11n adapter - iwconfig and ifconfig command (or Knoppix 6.0.1) seems can't even detect the existence of this adapter. The vendor website provides a driver which is called "RT2870 Wireless Lan Linux Driver". I am new, so dare not to do something screw up the entire system.
In summary, I have two (2) problems:
1. Not able to bring wlan0 up and running with 5.3.1
Further, how encryption is being implemented
2. Not able to detect draft N adapter with 6.0.1
Looks like problem is with the standard driver/configuaration
I am very new to Linux/Knoppix (2 weeks old) but have been working with PCs for quite some time.
I am able to follow (detailed) instructions but not sure what could be wrong in causing above problems.
Appreciate if you can help identifying (my) problems.
Regards,
Julian
