Motherboard M2N32-SLI Deluxe
I believe I know what the problem is, and perhaps how to fix it.
I was using RTL8187 for the on-board wireless card, which I know does not work, but also had no idea how to replace it. I may now know how to fix this problem.

Okay. I lied. I have no clue what to use instead of RTL8187. Can someone point me in the right direction.

[Terratoch]

Problem partially solved I have a new driver that works. I am going to try again with luck I may be setup.

[Terratoch]

Okay I am now positive I have the correct drivers. It is still not working. I have tried countless configuration settings.
Please help.

This plus no scan results = bad news. So where did you get the driver from eventually? Are you on a 64-bit Ubuntu installation by chance?

What again is the chipset of your wireless adapter?

And does the Windows driver that you are using support PEAP?

[Terratoch]

Chipset: RTL8187
I have several options available as to what windows driver to use.
They all came on the CD for my Motherboard
Which version would you recommend (98/ME/XP/Vista?)
Or something totally different.

[wieman01]

I recommend the XP version, 32-bit if you are running Ubuntu 32-bit.

Also, is your adapter listed anywhere here?

http://ndiswrapper.sourceforge.net/j...id,33/id,list/

[Terratoch]

Unfortunately the adapter doesn't really have a 'name', as it is built into the motherboard. but I can check the list and see.

But, the board is the M2N32 SLI Deluxe Wifi edition.

[Terratoch]

It looks like I could try the 8187B, L or one of the others from the site. that may do the trick. Ill just have to get it to my computer.

[wieman01]

OK, let me know how you go.
