SO....

I got 2 Laptop

On the first one , ( P3 650 + 384Mo RAM + 30Go ) I boot on live CD, Mount Usb HD, Go to Ndiswrapper and filling with Wireless parameter ( path to driver, ssid, wep )
When i Clic on OK, it's working, i got an IP address, and all is fine.

On the second laptop ( P1 266 + 32Mo RAM + 30Go ) I boot on live Cd, and I do EXACTLY the same thing.....but.... It won't work.
Everything i got is : "Connection failed"

I do NOT understand.

Please help, i don't want to install win2k on this laptop.

Does the system see the card?
Check dmesg for any potential problems.

Some older laptops do not support cardbus.
Many times you can tell by the newer pcmcia cards have a gold colored edge/strip. My old laptop will not work with those cards.
The older pcmcia silver colored edge work fine.

Sometimes pci=assign-busses boot option will make it work.

Look in the DSLpanel and the PCMCIA tool to see if your card is listed there.

If your card is seen then..

Second thing, ndiswrapper requires much ram, watch for that too.
You may want to stop torsmo and some other utils from running.

Yes the pcmcia card is present in the control panel, so it may work.

I'll try to stop some util to have enought ram for ndiswrapper ( ? )

Edit : Still have problem. Now booting from Hd install so Ndiswrapper tell me connection failed much more quickly but that's all

ndiswrapper -l show driver well installed...

Edit 2 :

This is what i get with dmesg :

I tried with pci=assign-busses => The same error.

When I launch ndiswrapper I have 15Mo of RAM free

I tried with no security encryption : The same error again...

Any hint ?

Error :

From the error posted, looks like not enough cached DMA memory.

* DMA memory: this memory is located under the 16 MB limit and is cached by the L1 and L2 caches
* 'normal' memory: this memory is located above the DMA limit and is cached by the L1 and L2 caches, it can not be used for DMA buffers
* slow memory: this memory is not cached or present on an add-on board, it can not be used for DMA buffers and using it for time critical kernel stack and SLAB would be disastrous for performance; we also don't want to use it for CPU intensive user applications

That doesn't look well for your small memory machine and using ndiswrapper.

So it's dead ?

Hello,

Have you tried creating/activating a swap file before running ndiswrapper?

Good Luck.

Posted by deadyoda on Dec. 24 2006,14:20

Yes, i got a 512Mo Swap partition.

Dsl is really fast with it
