WIfi device, no scan results

[Azhariq]

I have a Tp-link wn321g V4 wifi device...

lsusb 
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 148f:2070 Ralink Technology, Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I downloaded drivers from Ralinktech website

2010_0709_RT2870_Linux_STA_v2.4.0.1

and installed it with instructions in Readme_STA.

The device is blinking, and is listed under wireless networks...but it doesn't scans for any networks.

iwlist scan

[root@laptop linux]# iwlist scan

You don't mention anything about your computer hardware, operating system (what distribution+version+kernel) you are running, etc. The kernel makes a big difference, as do other issuse, such as do you have wpa_supplicant (if you are trying to access WPA protected connections). Also, have you tried manually configuring the WiFi connection? That may work, even if it doesn't see anything by scanning, or is not scanning. After all, the access point may not be publishing/broadcasting its SSID.

The network doesnt has any encryption or secret key, its an open network. And it is broadcasting its ssid.

And yes, i tried connecting manually, but it didnt worked.

[Rubberman]

One presumes that you tried to use this before you installed the driver? There are ralink driver modules with the standard kernel.

Sorry for the late reply, am outa city.

well i tried the built in rt2800usb driver, but i still get the same result. Wifi device cannot scan, or no scan results. Please help, its been almost two weeks that i am tryin to get this work.
