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). :D
Could you tell me more about solution to fix this problem, please?

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. :D

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?

If the wireless button is not being touched after it is switched on and then the wireless adapter is disapearing from device manager and drivers have been updated from computer manufacturer's website then it is possibly a hardware issue.

Can you post an ipconfig /all for review when connected to the wireless.

I've also installed easy display manager as well. But there is only the combination Fn+F9 is not working, while the others are normal (Fn+F6 to active sound, Fn+F10 to turn on/off numlock, etc...). And as I have said before, the wireless light below the touchpad is always on (blue light).

Here is the ipconfig /all after the wireless network is detected.

So, if it is the hardware issue, what is the part exactly?

" Wireless LAN adapter Wireless Network Connection" wasn't in the output when wireless wasn't working. Wireless adapter wasn't in device manager as well. Computer simply didn't see the adapter at all

Yes, that's right. As soon as the wireless adapter was in the device manager, the wifi signal was detected.

Now I just want to know that if it is a hardware issue or not? Since this problem happened 3 times lately, and someone told me that it is because the hardware is unstable.

And about the F9 key, it works normally on MS Word.

Fn+F9 not working...whio cares (unless it's related to another problem).

If wireless not working (totally disappeard from device manager):
The problem does only appear on booting up the machine? Or also if you are already browsing the internet wirelessly?
