I've just attempted to install the following product: http://www.tenda.cn/product/show.php?productid-349.html.

lsusb lists it as:

Bus 002 Device 002: ID 148f:3072 Ralink Technology, Corp.

After plugging it in, iwconfig showed:

no wireless extensions.

I was advised to, and did, compile compat-wireless. Since doing this, iwconfig now shows this:


wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on


However, the adapter still does not work. It has been suggested to me that it is a firmware issue, and dmesg seems to confirm this:


[ 12.267067] phy0 -> rt2x00lib_request_firmware: Error - Current firmware does not support detected chipset.
[ 12.337226] phy0 -> rt2x00lib_request_firmware: Error - Current firmware does not support detected chipset.

Can anyone suggest how I may be able to remedy this so that I can connect to wireless networks?

I'm inexperienced with Linux, so please don't assume any knowledge!

Thanks,

Tom.

The problem may actually be that this device is claimed by two different drivers that conflict. Let's do some diagnostics and see what's happening. Please post:
dmesg | grep -e rt2 -e rt3
lsmod | grep -e rt2 -e rt3Thanks.

I'm having pretty much exactly the same issue, I don't know if you can help, but
1) I -JUST- updated to 11.04 (it worked in 10)
2) The dongle still works in Win 7
3) I'm LOST! :-(
