Hi there,

I am in need of some help here.

I got my WG511 v3 made in China WiFi PCMCIA card up and running using ndiwrapper and the smc drivers mentioned in most of the tutorials.

I have a connection to my Linksys WRT54G WiFi router and can surf the internet.
Only problem is, that I could only connect to the router whithout any encryption. So no WEP or WPA setup at the moment.

I need some sort of protection setup, but nothing has worked till now.
I would be fine for the beginning, if I could at least get WEP setup, but I havn`t gotten any connection yet with WEP.

Could somebody guide me through setting up the WiFi card with Encryption. I would prefer WPA, but if that dosn`t work, WEP would do aswell.

This is kind of getting urgent.

Thank`s in advance.
Ken

Encription is not all that tough. You have to set up your router too. Set up a wep key there, and then set up the same key on your lappy.

What distro? Have a look to see if there are any config tools, or if you have to do it command line.

Hi,

thank`s for youre answer.

I am running Ubuntu drapper drake.

I had WEP setup on my Router and wanted to set it up on my laptop, but the laptop didn`t connect. First after I took out all the encpytion from router and laptop I could connect.

I will give it another try, setting it up and then rebooting.
Will let you know in a few minutes.

o.k. I setup WEP on my router and entered my code.

Then I setup the WiFi card for WEP and entered the code there answell. But it won`t connect.

I don`t know, if the Networl Tool that is standard in ubuntu is passing on the information or not, to the matching configuration file.

I think we should try to set it up by hand to see what happens.

Could somebody tell me how and what I need to enter in the command window?

Cheers
Ken

Try iwconfig wlan0 key FEFEFEFEFE where FEFEFEFEFE is the WEP key in hexadecimal. Add the line to /etc/network/interfaces .

o.k.

I entered iwconfig wlan0 key FEFEFEFEFE
and added the line key FEFEFEFEFE to /etc/network/interfaces.
Then I put this key into my router, but nothing is happening.
How can I get that key back out, so I can connect back up to the router?

Ken

No that was just an example, set up wep on your router first with a passphrase then use the resulting hex key in the iwconfig wlan0 key FEFEFEFEFE line replacing FEFEFEFEFE with your new key.

You can do WPA with that card - I had the same one. You have done the hard bit getting it to work with ndiswrapper. I've lent the laptop out now so don't have the details anymore.

Have you tried network-manager? It's a gui for wireless networks and it works for both WEP and WPA. If it asks you to set up a 'wallet' and if you don't want to be typing in a password everytime you connect, then give it no password. It will object, but accept.

Another method for WPA is with wpasupplicant.

I'm sorry I have no details. Both network-manager and wpasupplicant are available through the repositories, though you may need to enable universe (or even multiverse). Just google them and see what you can find. network-manager is a bit disturbing for it's lack of configurability, but it does work.

Sorry, but I forgot, that I posted here.

I tried all wikis and tutorials for setting up WPA and none work with my card.

I am going absolutely bonkers here.

Ken

There is more to getting a wireless connection working than just matching the keys. Yes, they have to match, but also have a look at:

ESSID: This parameter is set in your router, and some won't accept a connection unless this matches.

Mode: can be ad-hoc, master, repeater, or secondary ( most PC's would be secondary ).

Channel: This setting is set in the router, and controls the carrier frequency your card puts out. If they don't match, you won't connect.

Encryption: This is the keys, they must match, exactly. This can be a 64 bit or a 128 bit key. The longer the key the more secure.

There are more parameters, like RTS etc, my guess is the defaults will at least work most of the time.

At this point I don't know what tools you are using to configure your card, or what distro. A lot of this information is stored in the router.

Are you running DHCP? If yes, did you run a pump command to cause the system to try and aquire a IP address?

@ cammori,

as I mentioned, I am using ubuntu drapper.
In the german wikki`s there are tons of tutorials for the netgear wg511 v3 made in china WiFi card.

But for some reason, the tutorials I have tried, don`t want to work on my system.
Either I am doing something wrong, or I`m to stupid or I simply havn`t tried it long enough...

I tried a dhcp poll and I can see, that the card is trying t5o get an adress, but I have the feeling it is lloking in the wrong subnet.
Mine is 255.255.255.0 and the dhcp poll is going to 255.255.255.255

But I don`t know, if that ist the problem, since I also tried it with a atstic IP adress.

The card itself is blinking and trying to connect to my router.
I pulled the hex key from the router with a command, don`t which one, can`t remember at the moment, but I copy pasted it into the script (/etc/network/interface) according to the tutorial I went after.

But it just dosn`t want to connect.

I am going to reinstall everything this evening and give it a newe try.

Hi

This should help you determine if it is possible.

Set up your router to use WPA-PSK and put in your network key.

On your laptop make sure that you have your network drivers installed for the card (Hint: use iwconfig). Make sure that you have wpasupplicant installed as well (This does the WPA).

From a command shell and as root type (Obviously subsitute your network ID and key here:-);

wpa_passphrase ESSID NetworkKey >> /etc/wpa_supplicant.conf



Then type (I'm presuming its the Prism chipset);

wpa_supplicant -Dprism54 -iwlan0 -c /etc/wpa_supplicant.conf -dd

I am presuming that it is a prism chipset and that iwconfig show its as wlan0.

From another root terminal, type "dhclient wlan0". This should give you a IP address.

If this all works, install networkmanager. It can cope with most of this automatically.

Regards

Richard

As I recall, this card does not use the prism chipset, and blacklisting the prism driver module was key to getting the thing to work (which has been successfully done, right?). So that -D option would be different. Is it -Dndiswrapper ?

And check all your spelling - one wrong letter or upper/lower case error will stop you from getting through. Change your WPA passphrase to something simple, all in the same case, until you know that it works.

o.k.

I am just reinstalling the System again.

Then I will give this a try and let you know what is happening.

my passphrase is all lowercase and nothing special in there.

But I will keep you guys posted.

@ bernied

The card is based on the prism54 chipset, but will not work with the prism drivers. That is why I have do install it unsing ndiswrapper.
It dosn`t reall ymatter wich distri is involved, there are always problems with that specific card model. And the prism54 files need to be blacklisted.

Ken

o.k.

I got the connection established between the router and my WiFi car, but at the moment whithout security.

Here some outputs:

iwconfig wlan0

So we know, the card works.

What should I do next?
