Get wireless networking going?

[Lilt]

I'm trying to run Knoppix on a machine (windows HD died could get virtually nothing from it) with a DWL-510 wireless network card. Essentially: It's not working, I'll give you the various diagnostic outputs in a minute. Right now I have it connected via a cable to the motherboard's own network card, but this is causing a fair bit of clutter which I'd like to remove if possible.

The card itself has been the bane of my Linux use, as it thwarted my first few attempts to get Linux running as my primary OS back in 2000 or so. I'm thus fully willing to consider the possibility of getting a new card, if someone can name for me an exact card type that will work under Knoppix. This is partially also due to the fact that the windows drivers for the card crashed some software I used to run.

I had a look at the Networking FAQ and was a little intimidated and disheartened. Getting the drivers from the windows seems unlikely, as that drive is really quite far gone... Sometimes I can get scraps, but after a little access it just locks-up and is inaccessible until a reboot is done.

Here are what I hope are appropriate diagnostics, I don't know how much they'll help:

If you are making any wireless choices based on Knoppix, you are likely in for trouble. I have a wireless card that worked under 4.02 but stopped working under all versions of 5.x. I also find that several other wireless cards that I have that Knoppix never worked with work find under other hard disk installed versions of Linux and even other Live CD versions. I suggest trying a few alternate Live CD versions to see if you current card isn't now well supported after all (I would start with BackTrack 2, Mandriva and Puppy Linux, in that order). If you do come to the conclusion that your old card just isn't going to be supported, I would suggest either finding something that will work with a more wifi-friendly version of Linux or at the very least waiting until the next release of Knoppix (expected "real soon now"(tm)), otherwise you might get something that somehow does work with the current version but stops working when things change again.

[Lilt]

Thanks for your insight. perhaps it is a bit hasty to buy a network card based on Knoppix's compatibilities, but if you haven't gathered I don't really like this wireless network card. It's given me nothing but hassle whenever I try and use it, and I didn't manage to get it working at-all under Linux the last time I tried either. Meanwhile, I'm sure there are cards out there with the most common chipsets, which would have a much higher chance of being focused on.

Still, you're right that Knoppix isn't the only LiveCD out there. I'll try downloading some others and seeing if they can find it.

BTW: What's the difference between the CD and DVD versions? Would the DVD version be likely to contain drivers for more obscure model chip-sets?

Right now I'm still on the process of trying to figure-out what's still usable HD-wise. I'm willing to try and get the card running whilst I'm waiting for the various diagnostic/recovery programs I'm using to run/recover, perhaps more if I get somewhere. The program had a secondary disk with 2 partitions, and I just got a .5 TB SATA drive which I might put into that machine and see what I can get of the other disks contents'.

Hmm... After a few hours of poking around, I've finally gotten ndiswrapper to say that there's a card there, but it doesn't show-up under iwconfig. Ideas?

[Harry Kuhman]

BTW: What's the difference between the CD and DVD versions? Would the DVD version be likely to contain drivers for more obscure model chip-sets?

AFAIK the DVD version has lots more programs but I believe the kernel and drivers are the same. And I have no insight to offer on what your next step should be under Knoppix, since I can't get my card working either.

As to a card to buy, I can't make any recommendation. In part because I find wireless so messed up in 5.x that I wouldn't want to see anyone spend money on my recommendation and hope to get knoppix wireless working, and in part because of a tremd by almost all manufacturers to release cards based on different chip sets under the same model number (slipping in a different "version" number). You often can't get trhe version number from the outside of the package and will likely never find it when buying mail order, so if you still want to go with a new card I suggest dealing with a local retailer who will let you try before you buy, or who at least has a return policy that doesn't involve a restocking fee.

There are many websites that claim to tell you which chip set is in which card and how well each is supported under Linux. I can't speak to how accurate any of them are. If you want to find that information then I suggest starting with Google and searching for linux and chipset and wifi or wireless.

Hmm... I've managed to get a step further, and it's now reporting that it can intermittently see someone's wireless router. Sadly, it's still not seeing my linksys router... Possibly a signal strength thing, I might have to try and secure the aerial a bit more firmly (another reason to want a new card - the aerial is a bit loose and falls off if not secured).

I've also been trying to get WPA working, with no luck, so it is disabled on my router for the time being.

The issue that I was having was that the guides I was reading seemed to be expecting that I would not have the ndiswrapper already running. When I ran "modprobe ndiswraper", it was thus doing nothing. With "modprobe -r ndiswrapper" then "modprobe ndiswrapper", it finally reported finding wlan0.

Got BackTrack 2 downloaded and burnt, going to try and use it today.

[Lilt]

Update: BackTrack 2 finds the card, and I can get it doing a basic scan that shows-up the other router (not mine) it doesn't seem to be able to obtain an IP address. Might probe more later, right now I'm burning Mandriva.

[noobtolinux]

Try wpa_supplicant -c /etc/wpa_supplicant.conf -i wlan0 -D wext -dd where wlan0 is the wireless card. There seems to be an issue with calling ndiswrapper, as I used, but I got it to work with wext. It might help. Also, make sure that your wpa_supplicant.conf file is configured correctly. I am using WPA AES. For that to work I had to set up pairwise and group as CCMP only. Plus, make sure that the password is entered in hex format and without quotes. Here's what I have:

ctrl_interface=/var/run/wpa_supplicant

#COFFEE SHOP - Using simple WEP
network={
ssid="COFFESHOP"
key_mgmt=NONE
wep_tx_keyidx=0
wep_key0=6644565378
}

#HOME - Using WPA AES
network={
ssid="HOME"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
#psk="willubethere4ever"
psk=365342f8362524e1834abbd953edaf8979c4de38d7601f abb30a84d769953bb3
priority=2
}

Obviously the ESSID and PSK are not what I actually use, but these are to demonstrate my setup. Let me know if it helps.
