Windows 7: Laptop Samsung RV409 cannot detect wireless network

Laptop Samsung RV409 cannot detect wireless network

My laptop cannot detect any wireless right now, though the others are connecting normally. But when I plugged the cable network in, my laptop can connect to wired network. Previously, it could be able to connect to wifi, but suddenly, the wifi is like hidden from it. I also tried to check the wireless drivers but I couldn't find any.
Please help me fix this problem.

I hope that this does not sound silly, but does the WiFi have a on/off switch that you know of?
Check to see that it is on.

Can you try pressing Fn+F9

No it doesn't. In fact, I hadn't known about that Fn+F9 thing at first, but then, my friend had told me about that and I've tried it already. Unfortunately, it still didn't work.
That's why I have to ask here.
And FYI, it's so strange, but the Wifi switch is always on, no matter how many times I press Fn+F9 (and the wifi is still hidden).
Could you tell me more about solution to fix this problem, please?

below touchpad you see 5 icons. The third one is sort of triangle. What color has it?

Try Fn+F9 (the key with triangle)
You can only use this function after installing Windows XP/
Windows Vista/Windows 7 and installing the
Easy Display Manager

program and the wireless LAN driver with the
system software

media disk
.

What happens exactly if you press Fn+F9 ? Do you see something on screen?

wireless driver isn't in device manager. Also no "other devices". Not in ipconfig output as well. Do you know what wireless adapter it is?

Please check in the bios that the Wlan adapter is enabled under built in devices.

Sorry you guys for replying late.
The third light below the touchpad is always on, whether I press Fn+F9 or not. And when I do that, there is nothing happen on the screen as well.

For the device manager, I understand that there has been no wireless driver there. The problem is that, I have uninstalled and re-installed all the wireless driver so many times (Atheros - WLAN_Atheros_32bit_8.0.0.366 and Broadcom - WLAN_Broadcom_32bit_5.60.350.21), but nothing changed.

I don't know what is going on with my laptop. Now, the wireless driver is back on the device manager, but I cannot understand why? Because, after two days of installing the driver without any success, now it suddenly appears and my wifi is back.

Some says that it is because my hardware is unstable, is that true?

Anyway, thank you guys for all your concern. My wifi is back now, but does anyone know about my problem? I'm really worried, because this thing happened three times in the past 2 months, and I couldn't figure out what the cause is. Do I need to fix the hardware?
