WNDA 4100 (NetGear N900) Wireless Dual Band USB Adapter

[chili555]

I have this device as well and I've trying to compile the same driver but to no avail. Modprobe -l shows that the driver is installed, but that hasn't helped me.
I would love to get this working, has anyone had any luck with this?

I know there are other supported devices out there, but I haven't found any other dual band 450mps usb adapters that work either.

Do you have the same device?

Is the driver you compiled called rt5572sta? Please show us:

lsmod | grep rt5
dmesg | grep rt5

Thanks.

[lkbrow1]

I was able to compile and install the driver. But I still have no functionality.
I did a [user]>make
[user]>su
>make install

driver appears as a ra0 under ifconfig.

Now remove your current profile and create a new one. Check then:

iwconfig
rfkill list
lsmod
dmesg | grep rt5

Did you make the changes mentioned in the README?

I purchased one of these today. I will post my results.

I honestly cannot remember the last time I had a hardware issue with linux, but this is the 2nd Netgear device in week that probably isn't going to work.

I wish my dog hadn't chewed up my alfa =/

Any new info on this? I'm trying to get it working too.

I've compiled the package from Ralink just fine, and the module "rt3572sta" shows up when I do lsmod.

But it never shows up under 'ifconfig'

Any tips?

I'm not sure why it says RT2870 at the top, the Makefile says Chipset = 3572.

Maybe there's another place I need to set it to 3572 before compiling?

[chili555]

Ralink rewrites a lot of their USB drivers using the RT2870 driver as a template. Its mention here is meaningless.

The reason I asked for modinfo was so you and I could look in the alias fields for your device, xx:9012. I don't see it. That's because rt3572sta is not correct for your device. Please see: http://www.wikidevi.com/wiki/Netgear_WNDA4100

Chip 1: Ralink RT3573

Also please see here: http://ubuntuforums.org/showthread.p...ht=3573&page=2

Your device is also not mentioned in the files for rt3573sta, so you'll need to follow the same process as I outlined in post #13:

#endif /* RT35xx */
#ifdef RT3573
	{USB_DEVICE(0x148F,0x3573)}, /* Ralink 3573 */
	{USB_DEVICE(0x7392,0x7733)}, /* Edimax */
	{USB_DEVICE(0x0846,0x9012)}, /* Netgear */
	{USB_DEVICE(0x0B05,0x17AD)}, /*ASUS */
#endif /* RT3573 */
	{ }/* Terminating entry */

It may or may not work; if not, we'll try the rt5572sta package.

Please post back if you need more detailed instructions.

[ericosaurus]

That is fantastic, I got the 3573 driver and added the line you mentioned and it's up now!

But, it isn't connecting to the router. It gets a Mac address for the AP, but never gets an ip address. Is this probably an authentication problem?

I'm using WPA2PSK security mode in the rt2870sta.dat configuration file, should I be using WPA2 + wpa supplicant instead? How do I know when to use wpa supplicant?

Thanks so much for your help
