Hardware Trouble

Hi, Im having problems with ndiswrapper and ALSA. The problem with ndiswrapper is it refuses to associate with the access point despite the fact I know it is within range.

After running 'iwconfig wlan0 essid "AccessPoint"' it says the access point is not Non-Associated and the essid is Off/Any

The problem with ALSA is after successfully loading the module (snd-hda-intel) it refuses to play any sound from it. I can set the controls for it but thats all. Any program using ALSA freezes up such as amarok, mplayer etc

I have the feeling that these two problems are related but I don't know how or whats causing it.

I'm using Gentoo with kernel gentoo-sources-2.6.17-r8 and my motherboard is ALiveNFG-DVI with AMD 64 X2 4200+ running in 32 bit mode. The adapter is a usb netgear wg111v2

By the way I've had both the wireless adapter and ALSA running on it. It is only recently this has happened and it may be kernel related as I have been changing a few things quite a lot

what does iwlist wlan0 scan show you for available access points ? does it confirm the error you are getting ?

Is a Neighbors Access point stepping on yours ? (this is the most common issue I run into when helping people with their wireless)

You may have to rebuild your kernel use the gentoo guides on how to setup alsa and ndiswrapper make sure you have all the proper utilities.
Are there any errors at boot like modules missing, if this is the case you may have updated your kernel neglecting the separate modules. I have and asus a8n-vm csm running with the alsa module you use and it works fine (my mythtv box)

I hope this is of some help
